+
+Generic basic auth Authorization header field parser for whatever.
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```
+$ npm install basic-auth
+```
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var auth = require('basic-auth')
+```
+
+### auth(req)
+
+Get the basic auth credentials from the given request. The `Authorization`
+header is parsed and if the header is invalid, `undefined` is returned,
+otherwise an object with `name` and `pass` properties.
+
+### auth.parse(string)
+
+Parse a basic auth authorization header string. This will return an object
+with `name` and `pass` properties, or `undefined` if the string is invalid.
+
+## Example
+
+Pass a Node.js request object to the module export. If parsing fails
+`undefined` is returned, otherwise an object with `.name` and `.pass`.
+
+<!-- eslint-disable no-unused-vars, no-undef -->
+
+```js
+var auth = require('basic-auth')
+var user = auth(req)
+// => { name: 'something', pass: 'whatever' }
+```
+
+A header string from any other location can also be parsed with
+`auth.parse`, for example a `Proxy-Authorization` header:
+
+<!-- eslint-disable no-unused-vars, no-undef -->
+
+```js
+var auth = require('basic-auth')
+var user = auth.parse(req.getHeader('Proxy-Authorization'))
+```
+
+### With vanilla node.js http server
+
+```js
+var http = require('http')
+var auth = require('basic-auth')
+var compare = require('tsscmp')
+
+// Create server
+var server = http.createServer(function (req, res) {
+  var credentials = auth(req)
+
+  // Check credentials
+  // The "check" function will typically be against your user store
+  if (!credentials || !check(credentials.name, credentials.pass)) {
+    res.statusCode = 401
+    res.setHeader('WWW-Authenticate', 'Basic realm="example"')
+    res.end('Access denied')
+  } else {
+    res.end('Access granted')
+  }
+})
+
+// Basic function to validate credentials for example
+function check (name, pass) {
+  var valid = true
+
+  // Simple method to prevent short-circut and use timing-safe compare
+  valid = compare(name, 'john') && valid
+  valid = compare(pass, 'secret') && valid
+
+  return valid
+}
+
+// Listen
+server.listen(3000)
+```

+
+
+
+A tiny node.js debugging utility modelled after node core's debugging technique.
+
+**Discussion around the V3 API is under way [here](https://github.com/visionmedia/debug/issues/370)**
+
+## Installation
+
+```bash
+$ npm install debug
+```
+
+## Usage
+
+`debug` exposes a function; simply pass this function the name of your module, and it will return a decorated version of `console.error` for you to pass debug statements to. This will allow you to toggle the debug output for different parts of your module as well as the module as a whole.
+
+Example _app.js_:
+
+```js
+var debug = require('debug')('http')
+  , http = require('http')
+  , name = 'My App';
+
+// fake app
+
+debug('booting %s', name);
+
+http.createServer(function(req, res){
+  debug(req.method + ' ' + req.url);
+  res.end('hello\n');
+}).listen(3000, function(){
+  debug('listening');
+});
+
+// fake worker of some kind
+
+require('./worker');
+```
+
+Example _worker.js_:
+
+```js
+var debug = require('debug')('worker');
+
+setInterval(function(){
+  debug('doing some work');
+}, 1000);
+```
+
+ The __DEBUG__ environment variable is then used to enable these based on space or comma-delimited names. Here are some examples:
+
+  ![debug http and worker](http://f.cl.ly/items/18471z1H402O24072r1J/Screenshot.png)
+
+  ![debug worker](http://f.cl.ly/items/1X413v1a3M0d3C2c1E0i/Screenshot.png)
+
+#### Windows note
+
+ On Windows the environment variable is set using the `set` command.
+
+ ```cmd
+ set DEBUG=*,-not_this
+ ```
+
+ Note that PowerShell uses different syntax to set environment variables.
+
+ ```cmd
+ $env:DEBUG = "*,-not_this"
+  ```
+
+Then, run the program to be debugged as usual.
+
+## Millisecond diff
+
+  When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls.
+
+  ![](http://f.cl.ly/items/2i3h1d3t121M2Z1A3Q0N/Screenshot.png)
+
+  When stdout is not a TTY, `Date#toUTCString()` is used, making it more useful for logging the debug information as shown below:
+
+  ![](http://f.cl.ly/items/112H3i0e0o0P0a2Q2r11/Screenshot.png)
+
+## Conventions
+
+  If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser".
+
+## Wildcards
+
+  The `*` character may be used as a wildcard. Suppose for example your library has debuggers named "connect:bodyParser", "connect:compress", "connect:session", instead of listing all three with `DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do `DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`.
+
+  You can also exclude specific debuggers by prefixing them with a "-" character.  For example, `DEBUG=*,-connect:*` would include all debuggers except those starting with "connect:".
+
+## Environment Variables
+
+  When running through Node.js, you can set a few environment variables that will
+  change the behavior of the debug logging:
+
+| Name      | Purpose                                         |
+|-----------|-------------------------------------------------|
+| `DEBUG`   | Enables/disables specific debugging namespaces. |
+| `DEBUG_COLORS`| Whether or not to use colors in the debug output. |
+| `DEBUG_DEPTH` | Object inspection depth. |
+| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. |
+
+
+  __Note:__ The environment variables beginning with `DEBUG_` end up being
+  converted into an Options object that gets used with `%o`/`%O` formatters.
+  See the Node.js documentation for
+  [`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options)
+  for the complete list.
+
+## Formatters
+
+
+  Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting. Below are the officially supported formatters:
+
+| Formatter | Representation |
+|-----------|----------------|
+| `%O`      | Pretty-print an Object on multiple lines. |
+| `%o`      | Pretty-print an Object all on a single line. |
+| `%s`      | String. |
+| `%d`      | Number (both integer and float). |
+| `%j`      | JSON. Replaced with the string '[Circular]' if the argument contains circular references. |
+| `%%`      | Single percent sign ('%'). This does not consume an argument. |
+
+### Custom formatters
+
+  You can add custom formatters by extending the `debug.formatters` object. For example, if you wanted to add support for rendering a Buffer as hex with `%h`, you could do something like:
+
+```js
+const createDebug = require('debug')
+createDebug.formatters.h = (v) => {
+  return v.toString('hex')
+}
+
+// …elsewhere
+const debug = createDebug('foo')
+debug('this is hex: %h', new Buffer('hello world'))
+//   foo this is hex: 68656c6c6f20776f726c6421 +0ms
+```
+
+## Browser support
+  You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify),
+  or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest),
+  if you don't want to build it yourself.
+
+  Debug's enable state is currently persisted by `localStorage`.
+  Consider the situation shown below where you have `worker:a` and `worker:b`,
+  and wish to debug both. You can enable this using `localStorage.debug`:
+
+```js
+localStorage.debug = 'worker:*'
+```
+
+And then refresh the page.
+
+```js
+a = debug('worker:a');
+b = debug('worker:b');
+
+setInterval(function(){
+  a('doing some work');
+}, 1000);
+
+setInterval(function(){
+  b('doing some work');
+}, 1200);
+```
+
+#### Web Inspector Colors
+
+  Colors are also enabled on "Web Inspectors" that understand the `%c` formatting
+  option. These are WebKit web inspectors, Firefox ([since version
+  31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/))
+  and the Firebug plugin for Firefox (any version).
+
+  Colored output looks something like:
+
+  ![](https://cloud.githubusercontent.com/assets/71256/3139768/b98c5fd8-e8ef-11e3-862a-f7253b6f47c6.png)
+
+
+## Output streams
+
+  By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method:
+
+Example _stdout.js_:
+
+```js
+var debug = require('debug');
+var error = debug('app:error');
+
+// by default stderr is used
+error('goes to stderr!');
+
+var log = debug('app:log');
+// set this namespace to log via console.log
+log.log = console.log.bind(console); // don't forget to bind to console!
+log('goes to stdout');
+error('still goes to stderr!');
+
+// set all output to go via console.info
+// overrides all per-namespace log settings
+debug.log = console.info.bind(console);
+error('now goes to stdout via console.info');
+log('still goes to stdout, but via console.info now');
+```

+Deprecate all the things
+
+> With great modules comes great responsibility; mark things deprecated!
+
+## Install
+
+This module is installed directly using `npm`:
+
+```sh
+$ npm install depd
+```
+
+This module can also be bundled with systems like
+[Browserify](http://browserify.org/) or [webpack](https://webpack.github.io/),
+though by default this module will alter it's API to no longer display or
+track deprecations.
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var deprecate = require('depd')('my-module')
+```
+
+This library allows you to display deprecation messages to your users.
+This library goes above and beyond with deprecation warnings by
+introspection of the call stack (but only the bits that it is interested
+in).
+
+Instead of just warning on the first invocation of a deprecated
+function and never again, this module will warn on the first invocation
+of a deprecated function per unique call site, making it ideal to alert
+users of all deprecated uses across the code base, rather than just
+whatever happens to execute first.
+
+The deprecation warnings from this module also include the file and line
+information for the call into the module that the deprecated function was
+in.
+
+**NOTE** this library has a similar interface to the `debug` module, and
+this module uses the calling file to get the boundary for the call stacks,
+so you should always create a new `deprecate` object in each file and not
+within some central file.
+
+### depd(namespace)
+
+Create a new deprecate function that uses the given namespace name in the
+messages and will display the call site prior to the stack entering the
+file this function was called from. It is highly suggested you use the
+name of your module as the namespace.
+
+### deprecate(message)
+
+Call this function from deprecated code to display a deprecation message.
+This message will appear once per unique caller site. Caller site is the
+first call site in the stack in a different file from the caller of this
+function.
+
+If the message is omitted, a message is generated for you based on the site
+of the `deprecate()` call and will display the name of the function called,
+similar to the name displayed in a stack trace.
+
+### deprecate.function(fn, message)
+
+Call this function to wrap a given function in a deprecation message on any
+call to the function. An optional message can be supplied to provide a custom
+message.
+
+### deprecate.property(obj, prop, message)
+
+Call this function to wrap a given property on object in a deprecation message
+on any accessing or setting of the property. An optional message can be supplied
+to provide a custom message.
+
+The method must be called on the object where the property belongs (not
+inherited from the prototype).
+
+If the property is a data descriptor, it will be converted to an accessor
+descriptor in order to display the deprecation message.
+
+### process.on('deprecation', fn)
+
+This module will allow easy capturing of deprecation errors by emitting the
+errors as the type "deprecation" on the global `process`. If there are no
+listeners for this type, the errors are written to STDERR as normal, but if
+there are any listeners, nothing will be written to STDERR and instead only
+emitted. From there, you can write the errors in a different format or to a
+logging source.
+
+The error represents the deprecation and is emitted only once with the same
+rules as writing to STDERR. The error has the following properties:
+
+  - `message` - This is the message given by the library
+  - `name` - This is always `'DeprecationError'`
+  - `namespace` - This is the namespace the deprecation came from
+  - `stack` - This is the stack of the call to the deprecated thing
+
+Example `error.stack` output:
+
+```
+DeprecationError: my-cool-module deprecated oldfunction
+    at Object.<anonymous> ([eval]-wrapper:6:22)
+    at Module._compile (module.js:456:26)
+    at evalScript (node.js:532:25)
+    at startup (node.js:80:7)
+    at node.js:902:3
+```
+
+### process.env.NO_DEPRECATION
+
+As a user of modules that are deprecated, the environment variable `NO_DEPRECATION`
+is provided as a quick solution to silencing deprecation warnings from being
+output. The format of this is similar to that of `DEBUG`:
+
+```sh
+$ NO_DEPRECATION=my-module,othermod node app.js
+```
+
+This will suppress deprecations from being output for "my-module" and "othermod".
+The value is a list of comma-separated namespaces. To suppress every warning
+across all namespaces, use the value `*` for a namespace.
+
+Providing the argument `--no-deprecation` to the `node` executable will suppress
+all deprecations (only available in Node.js 0.8 or higher).
+
+**NOTE** This will not suppress the deperecations given to any "deprecation"
+event listeners, just the output to STDERR.
+
+### process.env.TRACE_DEPRECATION
+
+As a user of modules that are deprecated, the environment variable `TRACE_DEPRECATION`
+is provided as a solution to getting more detailed location information in deprecation
+warnings by including the entire stack trace. The format of this is the same as
+`NO_DEPRECATION`:
+
+```sh
+$ TRACE_DEPRECATION=my-module,othermod node app.js
+```
+
+This will include stack traces for deprecations being output for "my-module" and
+"othermod". The value is a list of comma-separated namespaces. To trace every
+warning across all namespaces, use the value `*` for a namespace.
+
+Providing the argument `--trace-deprecation` to the `node` executable will trace
+all deprecations (only available in Node.js 0.8 or higher).
+
+**NOTE** This will not trace the deperecations silenced by `NO_DEPRECATION`.
+
+## Display
+
+![message](files/message.png)
+
+When a user calls a function in your library that you mark deprecated, they
+will see the following written to STDERR (in the given colors, similar colors
+and layout to the `debug` module):
+
+```
+bright cyan    bright yellow
+|              |          reset       cyan

+               the word "deprecated"
+```
+
+If the user redirects their STDERR to a file or somewhere that does not support
+colors, they see (similar layout to the `debug` module):
+
+```

+                                             the word "deprecated"
+```
+
+## Examples
+
+### Deprecating all calls to a function
+
+This will display a deprecated message about "oldfunction" being deprecated
+from "my-module" on STDERR.
+
+```js
+var deprecate = require('depd')('my-cool-module')
+
+// message automatically derived from function name
+// Object.oldfunction
+exports.oldfunction = deprecate.function(function oldfunction () {
+  // all calls to function are deprecated
+})
+
+// specific message
+exports.oldfunction = deprecate.function(function () {
+  // all calls to function are deprecated
+}, 'oldfunction')
+```
+
+### Conditionally deprecating a function call
+
+This will display a deprecated message about "weirdfunction" being deprecated
+from "my-module" on STDERR when called with less than 2 arguments.
+
+```js
+var deprecate = require('depd')('my-cool-module')
+
+exports.weirdfunction = function () {
+  if (arguments.length < 2) {
+    // calls with 0 or 1 args are deprecated
+    deprecate('weirdfunction args < 2')
+  }
+}
+```
+
+When calling `deprecate` as a function, the warning is counted per call site
+within your own module, so you can display different deprecations depending
+on different situations and the users will still get all the warnings:
+
+```js
+var deprecate = require('depd')('my-cool-module')
+
+exports.weirdfunction = function () {
+  if (arguments.length < 2) {
+    // calls with 0 or 1 args are deprecated
+    deprecate('weirdfunction args < 2')
+  } else if (typeof arguments[0] !== 'string') {
+    // calls with non-string first argument are deprecated
+    deprecate('weirdfunction non-string first arg')
+  }
+}
+```
+
+### Deprecating property access
+
+This will display a deprecated message about "oldprop" being deprecated
+from "my-module" on STDERR when accessed. A deprecation will be displayed
+when setting the value and when getting the value.
+
+```js
+var deprecate = require('depd')('my-cool-module')
+
+exports.oldprop = 'something'
+
+// message automatically derives from property name
+deprecate.property(exports, 'oldprop')
+
+// explicit message
+deprecate.property(exports, 'oldprop', 'oldprop >= 0.10')
+```

+
+Get the first event in a set of event emitters and event pairs,
+then clean up after itself.
+
+## Install
+
+```sh
+$ npm install ee-first
+```
+
+## API
+
+```js
+var first = require('ee-first')
+```
+
+### first(arr, listener)
+
+Invoke `listener` on the first event from the list specified in `arr`. `arr` is
+an array of arrays, with each array in the format `[ee, ...event]`. `listener`
+will be called only once, the first time any of the given events are emitted. If
+`error` is one of the listened events, then if that fires first, the `listener`
+will be given the `err` argument.
+
+The `listener` is invoked as `listener(err, ee, event, args)`, where `err` is the
+first argument emitted from an `error` event, if applicable; `ee` is the event
+emitter that fired; `event` is the string event name that fired; and `args` is an
+array of the arguments that were emitted on the event.
+
+```js
+var ee1 = new EventEmitter()
+var ee2 = new EventEmitter()
+
+first([
+  [ee1, 'close', 'end', 'error'],
+  [ee2, 'error']
+], function (err, ee, event, args) {
+  // listener invoked
+})
+```
+
+#### .cancel()
+
+The group of listeners can be cancelled before being invoked and have all the event
+listeners removed from the underlying event emitters.
+
+```js
+var thunk = first([
+  [ee1, 'close', 'end', 'error'],
+  [ee2, 'error']
+], function (err, ee, event, args) {
+  // listener invoked
+})
+
+// cancel and clean up
+thunk.cancel()
+```

+
+HTTP request logger middleware for node.js
+
+> Named after [Dexter](http://en.wikipedia.org/wiki/Dexter_Morgan), a show you should not watch until completion.
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var morgan = require('morgan')
+```
+
+### morgan(format, options)
+
+Create a new morgan logger middleware function using the given `format` and `options`.
+The `format` argument may be a string of a predefined name (see below for the names),
+a string of a format string, or a function that will produce a log entry.
+
+The `format` function will be called with three arguments `tokens`, `req`, and `res`,
+where `tokens` is an object with all defined tokens, `req` is the HTTP request and `res`
+is the HTTP response. The function is expected to return a string that will be the log
+line, or `undefined` / `null` to skip logging.
+
+#### Using a predefined format string
+
+<!-- eslint-disable no-undef -->
+
+```js
+morgan('tiny')
+```
+
+#### Using format string of predefined tokens
+
+<!-- eslint-disable no-undef -->
+
+```js
+morgan(':method :url :status :res[content-length] - :response-time ms')
+```
+
+#### Using a custom format function
+
+<!-- eslint-disable no-undef -->
+
+``` js
+morgan(function (tokens, req, res) {
+  return [
+    tokens.method(req, res),
+    tokens.url(req, res),
+    tokens.status(req, res),
+    tokens.res(req, res, 'content-length'), '-',
+    tokens['response-time'](req, res), 'ms'
+  ].join(' ')
+})
+```
+
+#### Options
+
+Morgan accepts these properties in the options object.
+
+##### immediate
+
+Write log line on request instead of response. This means that a requests will
+be logged even if the server crashes, _but data from the response (like the
+response code, content length, etc.) cannot be logged_.
+
+##### skip
+
+Function to determine if logging is skipped, defaults to `false`. This function
+will be called as `skip(req, res)`.
+
+<!-- eslint-disable no-undef -->
+
+```js
+// EXAMPLE: only log error responses
+morgan('combined', {
+  skip: function (req, res) { return res.statusCode < 400 }
+})
+```
+
+##### stream
+
+Output stream for writing log lines, defaults to `process.stdout`.
+
+#### Predefined Formats
+
+There are various pre-defined formats provided:
+
+##### combined
+
+Standard Apache combined log output.
+
+```
+:remote-addr - :remote-user [:date[clf]] ":method :url HTTP/:http-version" :status :res[content-length] ":referrer" ":user-agent"
+```
+
+##### common
+
+Standard Apache common log output.
+
+```
+:remote-addr - :remote-user [:date[clf]] ":method :url HTTP/:http-version" :status :res[content-length]
+```
+
+##### dev
+
+Concise output colored by response status for development use. The `:status`
+token will be colored green for success codes, red for server error codes,
+yellow for client error codes, cyan for redirection codes, and uncolored
+for information codes.
+
+```
+:method :url :status :response-time ms - :res[content-length]
+```
+
+##### short
+
+Shorter than default, also including response time.
+
+```
+:remote-addr :remote-user :method :url HTTP/:http-version :status :res[content-length] - :response-time ms
+```
+
+##### tiny
+
+The minimal output.
+
+```
+:method :url :status :res[content-length] - :response-time ms
+```
+
+#### Tokens
+
+##### Creating new tokens
+
+To define a token, simply invoke `morgan.token()` with the name and a callback function.
+This callback function is expected to return a string value. The value returned is then
+available as ":type" in this case:
+
+<!-- eslint-disable no-undef -->
+
+```js
+morgan.token('type', function (req, res) { return req.headers['content-type'] })
+```
+
+Calling `morgan.token()` using the same name as an existing token will overwrite that
+token definition.
+
+The token function is expected to be called with the arguments `req` and `res`, representing
+the HTTP request and HTTP response. Additionally, the token can accept further arguments of
+it's choosing to customize behavior.
+
+##### :date[format]
+
+The current date and time in UTC. The available formats are:
+
+  - `clf` for the common log format (`"10/Oct/2000:13:55:36 +0000"`)
+  - `iso` for the common ISO 8601 date time format (`2000-10-10T13:55:36.000Z`)
+  - `web` for the common RFC 1123 date time format (`Tue, 10 Oct 2000 13:55:36 GMT`)
+
+If no format is given, then the default is `web`.
+
+##### :http-version
+
+The HTTP version of the request.
+
+##### :method
+
+The HTTP method of the request.
+
+##### :referrer
+
+The Referrer header of the request. This will use the standard mis-spelled Referer header if exists, otherwise Referrer.
+
+##### :remote-addr
+
+The remote address of the request. This will use `req.ip`, otherwise the standard `req.connection.remoteAddress` value (socket address).
+
+##### :remote-user
+
+The user authenticated as part of Basic auth for the request.
+
+##### :req[header]
+
+The given `header` of the request. If the header is not present, the
+value will be displayed as `"-"` in the log.
+
+##### :res[header]
+
+The given `header` of the response. If the header is not present, the
+value will be displayed as `"-"` in the log.
+
+##### :response-time[digits]
+
+The time between the request coming into `morgan` and when the response
+headers are written, in milliseconds.
+
+The `digits` argument is a number that specifies the number of digits to
+include on the number, defaulting to `3`, which provides microsecond precision.
+
+##### :status
+
+The status code of the response.
+
+If the request/response cycle completes before a response was sent to the
+client (for example, the TCP socket closed prematurely by a client aborting
+the request), then the status will be empty (displayed as `"-"` in the log).
+
+##### :total-time[digits]
+
+The time between the request coming into `morgan` and when the response
+has finished being written out to the connection, in milliseconds.
+
+The `digits` argument is a number that specifies the number of digits to
+include on the number, defaulting to `3`, which provides microsecond precision.
+
+##### :url
+
+The URL of the request. This will use `req.originalUrl` if exists, otherwise `req.url`.
+
+##### :user-agent
+
+The contents of the User-Agent header of the request.
+
+### morgan.compile(format)
+
+Compile a format string into a `format` function for use by `morgan`. A format string
+is a string that represents a single log line and can utilize token syntax.
+Tokens are references by `:token-name`. If tokens accept arguments, they can
+be passed using `[]`, for example: `:token-name[pretty]` would pass the string
+`'pretty'` as an argument to the token `token-name`.
+
+The function returned from `morgan.compile` takes three arguments `tokens`, `req`, and
+`res`, where `tokens` is object with all defined tokens, `req` is the HTTP request and
+`res` is the HTTP response. The function will return a string that will be the log line,
+or `undefined` / `null` to skip logging.
+
+Normally formats are defined using `morgan.format(name, format)`, but for certain
+advanced uses, this compile function is directly available.
+
+## Examples
+
+### express/connect
+
+Simple app that will log all request in the Apache combined format to STDOUT
+
+```js
+var express = require('express')
+var morgan = require('morgan')
+
+var app = express()
+
+app.use(morgan('combined'))
+
+app.get('/', function (req, res) {
+  res.send('hello, world!')
+})
+```
+
+### vanilla http server
+
+Simple app that will log all request in the Apache combined format to STDOUT
+
+```js
+var finalhandler = require('finalhandler')
+var http = require('http')
+var morgan = require('morgan')
+
+// create "middleware"
+var logger = morgan('combined')
+
+http.createServer(function (req, res) {
+  var done = finalhandler(req, res)
+  logger(req, res, function (err) {
+    if (err) return done(err)
+
+    // respond to request
+    res.setHeader('content-type', 'text/plain')
+    res.end('hello, world!')
+  })
+})
+```
+
+### write logs to a file
+
+#### single file
+
+Simple app that will log all requests in the Apache combined format to the file
+`access.log`.
+
+```js
+var express = require('express')
+var fs = require('fs')
+var morgan = require('morgan')
+var path = require('path')
+
+var app = express()
+
+// create a write stream (in append mode)
+var accessLogStream = fs.createWriteStream(path.join(__dirname, 'access.log'), { flags: 'a' })
+
+// setup the logger
+app.use(morgan('combined', { stream: accessLogStream }))
+
+app.get('/', function (req, res) {
+  res.send('hello, world!')
+})
+```
+
+#### log file rotation
+
+Simple app that will log all requests in the Apache combined format to one log
+file per day in the `log/` directory using the
+[rotating-file-stream module](https://www.npmjs.com/package/rotating-file-stream).
+
+```js
+var express = require('express')
+var morgan = require('morgan')
+var path = require('path')
+var rfs = require('rotating-file-stream') // version 2.x
+
+var app = express()
+
+// create a rotating write stream
+var accessLogStream = rfs.createStream('access.log', {
+  interval: '1d', // rotate daily
+  path: path.join(__dirname, 'log')
+})
+
+// setup the logger
+app.use(morgan('combined', { stream: accessLogStream }))
+
+app.get('/', function (req, res) {
+  res.send('hello, world!')
+})
+```
+
+### split / dual logging
+
+The `morgan` middleware can be used as many times as needed, enabling
+combinations like:
+
+  * Log entry on request and one on response
+  * Log all requests to file, but errors to console
+  * ... and more!
+
+Sample app that will log all requests to a file using Apache format, but
+error responses are logged to the console:
+
+```js
+var express = require('express')
+var fs = require('fs')
+var morgan = require('morgan')
+var path = require('path')
+
+var app = express()
+
+// log only 4xx and 5xx responses to console
+app.use(morgan('dev', {
+  skip: function (req, res) { return res.statusCode < 400 }
+}))
+
+// log all requests to access.log
+app.use(morgan('common', {
+  stream: fs.createWriteStream(path.join(__dirname, 'access.log'), { flags: 'a' })
+}))
+
+app.get('/', function (req, res) {
+  res.send('hello, world!')
+})
+```
+
+### use custom token formats
+
+Sample app that will use custom token formats. This adds an ID to all requests and displays it using the `:id` token.
+
+```js
+var express = require('express')
+var morgan = require('morgan')
+var uuid = require('node-uuid')
+
+morgan.token('id', function getId (req) {
+  return req.id
+})
+
+var app = express()
+
+app.use(assignId)
+app.use(morgan(':id :method :url :response-time'))
+
+app.get('/', function (req, res) {
+  res.send('hello, world!')
+})
+
+function assignId (req, res, next) {
+  req.id = uuid.v4()
+  next()
+}
+```

+[![Build Status](https://travis-ci.org/zeit/ms.svg?branch=master)](https://travis-ci.org/zeit/ms)
+[![Slack Channel](http://zeit-slackin.now.sh/badge.svg)](https://zeit.chat/)
+
+Use this package to easily convert various time formats to milliseconds.
+
+## Examples
+
+```js
+ms('2 days')  // 172800000
+ms('1d')      // 86400000
+ms('10h')     // 36000000
+ms('2.5 hrs') // 9000000
+ms('2h')      // 7200000
+ms('1m')      // 60000
+ms('5s')      // 5000
+ms('1y')      // 31557600000
+ms('100')     // 100
+```
+
+### Convert from milliseconds
+
+```js
+ms(60000)             // "1m"
+ms(2 * 60000)         // "2m"
+ms(ms('10 hours'))    // "10h"
+```
+
+### Time format written-out
+
+```js
+ms(60000, { long: true })             // "1 minute"
+ms(2 * 60000, { long: true })         // "2 minutes"
+ms(ms('10 hours'), { long: true })    // "10 hours"
+```
+
+## Features
+
+- Works both in [node](https://nodejs.org) and in the browser.
+- If a number is supplied to `ms`, a string with a unit is returned.
+- If a string that contains the number is supplied, it returns it as a number (e.g.: it returns `100` for `'100'`).
+- If you pass a string with a number and a valid unit, the number of equivalent ms is returned.
+
+## Caught a bug?
+
+1. [Fork](https://help.github.com/articles/fork-a-repo/) this repository to your own GitHub account and then [clone](https://help.github.com/articles/cloning-a-repository/) it to your local device
+2. Link the package to the global module directory: `npm link`
+3. Within the module you want to test your local development instance of ms, just link it to the dependencies: `npm link ms`. Instead of the default one from npm, node will now use your clone of ms!
+
+As always, you can run the tests using: `npm test`

+
+Execute a callback when a HTTP request closes, finishes, or errors.
+
+## Install
+
+```sh
+$ npm install on-finished
+```
+
+## API
+
+```js
+var onFinished = require('on-finished')
+```
+
+### onFinished(res, listener)
+
+Attach a listener to listen for the response to finish. The listener will
+be invoked only once when the response finished. If the response finished
+to an error, the first argument will contain the error. If the response
+has already finished, the listener will be invoked.
+
+Listening to the end of a response would be used to close things associated
+with the response, like open files.
+
+Listener is invoked as `listener(err, res)`.
+
+```js
+onFinished(res, function (err, res) {
+  // clean up open fds, etc.
+  // err contains the error is request error'd
+})
+```
+
+### onFinished(req, listener)
+
+Attach a listener to listen for the request to finish. The listener will
+be invoked only once when the request finished. If the request finished
+to an error, the first argument will contain the error. If the request
+has already finished, the listener will be invoked.
+
+Listening to the end of a request would be used to know when to continue
+after reading the data.
+
+Listener is invoked as `listener(err, req)`.
+
+```js
+var data = ''
+
+req.setEncoding('utf8')
+res.on('data', function (str) {
+  data += str
+})
+
+onFinished(req, function (err, req) {
+  // data is read unless there is err
+})
+```
+
+### onFinished.isFinished(res)
+
+Determine if `res` is already finished. This would be useful to check and
+not even start certain operations if the response has already finished.
+
+### onFinished.isFinished(req)
+
+Determine if `req` is already finished. This would be useful to check and
+not even start certain operations if the request has already finished.
+
+## Special Node.js requests
+
+### HTTP CONNECT method
+
+The meaning of the `CONNECT` method from RFC 7231, section 4.3.6:
+
+> The CONNECT method requests that the recipient establish a tunnel to
+> the destination origin server identified by the request-target and,
+> if successful, thereafter restrict its behavior to blind forwarding
+> of packets, in both directions, until the tunnel is closed.  Tunnels
+> are commonly used to create an end-to-end virtual connection, through
+> one or more proxies, which can then be secured using TLS (Transport
+> Layer Security, [RFC5246]).
+
+In Node.js, these request objects come from the `'connect'` event on
+the HTTP server.
+
+When this module is used on a HTTP `CONNECT` request, the request is
+considered "finished" immediately, **due to limitations in the Node.js
+interface**. This means if the `CONNECT` request contains a request entity,
+the request will be considered "finished" even before it has been read.
+
+There is no such thing as a response object to a `CONNECT` request in
+Node.js, so there is no support for for one.
+
+### HTTP Upgrade request
+
+The meaning of the `Upgrade` header from RFC 7230, section 6.1:
+
+> The "Upgrade" header field is intended to provide a simple mechanism
+> for transitioning from HTTP/1.1 to some other protocol on the same
+> connection.
+
+In Node.js, these request objects come from the `'upgrade'` event on
+the HTTP server.
+
+When this module is used on a HTTP request with an `Upgrade` header, the
+request is considered "finished" immediately, **due to limitations in the
+Node.js interface**. This means if the `Upgrade` request contains a request
+entity, the request will be considered "finished" even before it has been
+read.
+
+There is no such thing as a response object to a `Upgrade` request in
+Node.js, so there is no support for for one.
+
+## Example
+
+The following code ensures that file descriptors are always closed
+once the response finishes.
+
+```js
+var destroy = require('destroy')
+var http = require('http')
+var onFinished = require('on-finished')
+
+http.createServer(function onRequest(req, res) {
+  var stream = fs.createReadStream('package.json')
+  stream.pipe(res)
+  onFinished(res, function (err) {
+    destroy(stream)
+  })
+})
+```

+
+Execute a listener when a response is about to write headers.
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install on-headers
+```
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var onHeaders = require('on-headers')
+```
+
+### onHeaders(res, listener)
+
+This will add the listener `listener` to fire when headers are emitted for `res`.
+The listener is passed the `response` object as it's context (`this`). Headers are
+considered to be emitted only once, right before they are sent to the client.
+
+When this is called multiple times on the same `res`, the `listener`s are fired
+in the reverse order they were added.
+
+## Examples
+
+```js
+var http = require('http')
+var onHeaders = require('on-headers')
+
+http
+  .createServer(onRequest)
+  .listen(3000)
+
+function addPoweredBy () {
+  // set if not set by end of request
+  if (!this.getHeader('X-Powered-By')) {
+    this.setHeader('X-Powered-By', 'Node.js')
+  }
+}
+
+function onRequest (req, res) {
+  onHeaders(res, addPoweredBy)
+
+  res.setHeader('Content-Type', 'text/plain')
+  res.end('hello!')
+}
+```
+
+## Testing
+
+```sh
+$ npm test
+```

+#### Safer Node.js Buffer API
+
+**Use the new Node.js Buffer APIs (`Buffer.from`, `Buffer.alloc`,
+`Buffer.allocUnsafe`, `Buffer.allocUnsafeSlow`) in all versions of Node.js.**
+
+**Uses the built-in implementation when available.**
+
+## install
+
+```
+npm install safe-buffer
+```
+
+## usage
+
+The goal of this package is to provide a safe replacement for the node.js `Buffer`.
+
+It's a drop-in replacement for `Buffer`. You can use it by adding one `require` line to
+the top of your node.js modules:
+
+```js
+var Buffer = require('safe-buffer').Buffer
+
+// Existing buffer code will continue to work without issues:
+
+new Buffer('hey', 'utf8')
+new Buffer([1, 2, 3], 'utf8')
+new Buffer(obj)
+new Buffer(16) // create an uninitialized buffer (potentially unsafe)
+
+// But you can use these new explicit APIs to make clear what you want:
+
+Buffer.from('hey', 'utf8') // convert from many types to a Buffer
+Buffer.alloc(16) // create a zero-filled buffer (safe)
+Buffer.allocUnsafe(16) // create an uninitialized buffer (potentially unsafe)
+```
+
+## api
+
+### Class Method: Buffer.from(array)
+<!-- YAML
+added: v3.0.0
+-->
+
+* `array` {Array}
+
+Allocates a new `Buffer` using an `array` of octets.
+
+```js
+const buf = Buffer.from([0x62,0x75,0x66,0x66,0x65,0x72]);
+  // creates a new Buffer containing ASCII bytes
+  // ['b','u','f','f','e','r']
+```
+
+A `TypeError` will be thrown if `array` is not an `Array`.
+
+### Class Method: Buffer.from(arrayBuffer[, byteOffset[, length]])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `arrayBuffer` {ArrayBuffer} The `.buffer` property of a `TypedArray` or
+  a `new ArrayBuffer()`
+* `byteOffset` {Number} Default: `0`
+* `length` {Number} Default: `arrayBuffer.length - byteOffset`
+
+When passed a reference to the `.buffer` property of a `TypedArray` instance,
+the newly created `Buffer` will share the same allocated memory as the
+TypedArray.
+
+```js
+const arr = new Uint16Array(2);
+arr[0] = 5000;
+arr[1] = 4000;
+
+const buf = Buffer.from(arr.buffer); // shares the memory with arr;
+
+console.log(buf);
+  // Prints: <Buffer 88 13 a0 0f>
+
+// changing the TypedArray changes the Buffer also
+arr[1] = 6000;
+
+console.log(buf);
+  // Prints: <Buffer 88 13 70 17>
+```
+
+The optional `byteOffset` and `length` arguments specify a memory range within
+the `arrayBuffer` that will be shared by the `Buffer`.
+
+```js
+const ab = new ArrayBuffer(10);
+const buf = Buffer.from(ab, 0, 2);
+console.log(buf.length);
+  // Prints: 2
+```
+
+A `TypeError` will be thrown if `arrayBuffer` is not an `ArrayBuffer`.
+
+### Class Method: Buffer.from(buffer)
+<!-- YAML
+added: v3.0.0
+-->
+
+* `buffer` {Buffer}
+
+Copies the passed `buffer` data onto a new `Buffer` instance.
+
+```js
+const buf1 = Buffer.from('buffer');
+const buf2 = Buffer.from(buf1);
+
+buf1[0] = 0x61;
+console.log(buf1.toString());
+  // 'auffer'
+console.log(buf2.toString());
+  // 'buffer' (copy is not changed)
+```
+
+A `TypeError` will be thrown if `buffer` is not a `Buffer`.
+
+### Class Method: Buffer.from(str[, encoding])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `str` {String} String to encode.
+* `encoding` {String} Encoding to use, Default: `'utf8'`
+
+Creates a new `Buffer` containing the given JavaScript string `str`. If
+provided, the `encoding` parameter identifies the character encoding.
+If not provided, `encoding` defaults to `'utf8'`.
+
+```js
+const buf1 = Buffer.from('this is a tést');
+console.log(buf1.toString());
+  // prints: this is a tést
+console.log(buf1.toString('ascii'));
+  // prints: this is a tC)st
+
+const buf2 = Buffer.from('7468697320697320612074c3a97374', 'hex');
+console.log(buf2.toString());
+  // prints: this is a tést
+```
+
+A `TypeError` will be thrown if `str` is not a string.
+
+### Class Method: Buffer.alloc(size[, fill[, encoding]])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+* `fill` {Value} Default: `undefined`
+* `encoding` {String} Default: `utf8`
+
+Allocates a new `Buffer` of `size` bytes. If `fill` is `undefined`, the
+`Buffer` will be *zero-filled*.
+
+```js
+const buf = Buffer.alloc(5);
+console.log(buf);
+  // <Buffer 00 00 00 00 00>
+```
+
+The `size` must be less than or equal to the value of
+`require('buffer').kMaxLength` (on 64-bit architectures, `kMaxLength` is
+`(2^31)-1`). Otherwise, a [`RangeError`][] is thrown. A zero-length Buffer will
+be created if a `size` less than or equal to 0 is specified.
+
+If `fill` is specified, the allocated `Buffer` will be initialized by calling
+`buf.fill(fill)`. See [`buf.fill()`][] for more information.
+
+```js
+const buf = Buffer.alloc(5, 'a');
+console.log(buf);
+  // <Buffer 61 61 61 61 61>
+```
+
+If both `fill` and `encoding` are specified, the allocated `Buffer` will be
+initialized by calling `buf.fill(fill, encoding)`. For example:
+
+```js
+const buf = Buffer.alloc(11, 'aGVsbG8gd29ybGQ=', 'base64');
+console.log(buf);
+  // <Buffer 68 65 6c 6c 6f 20 77 6f 72 6c 64>
+```
+
+Calling `Buffer.alloc(size)` can be significantly slower than the alternative
+`Buffer.allocUnsafe(size)` but ensures that the newly created `Buffer` instance
+contents will *never contain sensitive data*.
+
+A `TypeError` will be thrown if `size` is not a number.
+
+### Class Method: Buffer.allocUnsafe(size)
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+
+Allocates a new *non-zero-filled* `Buffer` of `size` bytes.  The `size` must
+be less than or equal to the value of `require('buffer').kMaxLength` (on 64-bit
+architectures, `kMaxLength` is `(2^31)-1`). Otherwise, a [`RangeError`][] is
+thrown. A zero-length Buffer will be created if a `size` less than or equal to
+0 is specified.
+
+The underlying memory for `Buffer` instances created in this way is *not
+initialized*. The contents of the newly created `Buffer` are unknown and
+*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such
+`Buffer` instances to zeroes.
+
+```js
+const buf = Buffer.allocUnsafe(5);
+console.log(buf);
+  // <Buffer 78 e0 82 02 01>
+  // (octets will be different, every time)
+buf.fill(0);
+console.log(buf);
+  // <Buffer 00 00 00 00 00>
+```
+
+A `TypeError` will be thrown if `size` is not a number.
+
+Note that the `Buffer` module pre-allocates an internal `Buffer` instance of
+size `Buffer.poolSize` that is used as a pool for the fast allocation of new
+`Buffer` instances created using `Buffer.allocUnsafe(size)` (and the deprecated
+`new Buffer(size)` constructor) only when `size` is less than or equal to
+`Buffer.poolSize >> 1` (floor of `Buffer.poolSize` divided by two). The default
+value of `Buffer.poolSize` is `8192` but can be modified.
+
+Use of this pre-allocated internal memory pool is a key difference between
+calling `Buffer.alloc(size, fill)` vs. `Buffer.allocUnsafe(size).fill(fill)`.
+Specifically, `Buffer.alloc(size, fill)` will *never* use the internal Buffer
+pool, while `Buffer.allocUnsafe(size).fill(fill)` *will* use the internal
+Buffer pool if `size` is less than or equal to half `Buffer.poolSize`. The
+difference is subtle but can be important when an application requires the
+additional performance that `Buffer.allocUnsafe(size)` provides.
+
+### Class Method: Buffer.allocUnsafeSlow(size)
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+
+Allocates a new *non-zero-filled* and non-pooled `Buffer` of `size` bytes.  The
+`size` must be less than or equal to the value of
+`require('buffer').kMaxLength` (on 64-bit architectures, `kMaxLength` is
+`(2^31)-1`). Otherwise, a [`RangeError`][] is thrown. A zero-length Buffer will
+be created if a `size` less than or equal to 0 is specified.
+
+The underlying memory for `Buffer` instances created in this way is *not
+initialized*. The contents of the newly created `Buffer` are unknown and
+*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such
+`Buffer` instances to zeroes.
+
+When using `Buffer.allocUnsafe()` to allocate new `Buffer` instances,
+allocations under 4KB are, by default, sliced from a single pre-allocated
+`Buffer`. This allows applications to avoid the garbage collection overhead of
+creating many individually allocated Buffers. This approach improves both
+performance and memory usage by eliminating the need to track and cleanup as
+many `Persistent` objects.
+
+However, in the case where a developer may need to retain a small chunk of
+memory from a pool for an indeterminate amount of time, it may be appropriate
+to create an un-pooled Buffer instance using `Buffer.allocUnsafeSlow()` then
+copy out the relevant bits.
+
+```js
+// need to keep around a few small chunks of memory
+const store = [];
+
+socket.on('readable', () => {
+  const data = socket.read();
+  // allocate for retained data
+  const sb = Buffer.allocUnsafeSlow(10);
+  // copy the data into the new allocation
+  data.copy(sb, 0, 0, 10);
+  store.push(sb);
+});
+```
+
+Use of `Buffer.allocUnsafeSlow()` should be used only as a last resort *after*
+a developer has observed undue memory retention in their applications.
+
+A `TypeError` will be thrown if `size` is not a number.
+
+### All the Rest
+
+The rest of the `Buffer` API is exactly the same as in node.js.
+[See the docs](https://nodejs.org/api/buffer.html).
+
+
+## Related links
+
+- [Node.js issue: Buffer(number) is unsafe](https://github.com/nodejs/node/issues/4660)
+- [Node.js Enhancement Proposal: Buffer.from/Buffer.alloc/Buffer.zalloc/Buffer() soft-deprecate](https://github.com/nodejs/node-eps/pull/4)
+
+## Why is `Buffer` unsafe?
+
+Today, the node.js `Buffer` constructor is overloaded to handle many different argument
+types like `String`, `Array`, `Object`, `TypedArrayView` (`Uint8Array`, etc.),
+`ArrayBuffer`, and also `Number`.
+
+The API is optimized for convenience: you can throw any type at it, and it will try to do
+what you want.
+
+Because the Buffer constructor is so powerful, you often see code like this:
+
+```js
+// Convert UTF-8 strings to hex
+function toHex (str) {
+  return new Buffer(str).toString('hex')
+}
+```
+
+***But what happens if `toHex` is called with a `Number` argument?***
+
+### Remote Memory Disclosure
+
+If an attacker can make your program call the `Buffer` constructor with a `Number`
+argument, then they can make it allocate uninitialized memory from the node.js process.
+This could potentially disclose TLS private keys, user data, or database passwords.
+
+When the `Buffer` constructor is passed a `Number` argument, it returns an
+**UNINITIALIZED** block of memory of the specified `size`. When you create a `Buffer` like
+this, you **MUST** overwrite the contents before returning it to the user.
+
+From the [node.js docs](https://nodejs.org/api/buffer.html#buffer_new_buffer_size):
+
+> `new Buffer(size)`
+>
+> - `size` Number
+>
+> The underlying memory for `Buffer` instances created in this way is not initialized.
+> **The contents of a newly created `Buffer` are unknown and could contain sensitive
+> data.** Use `buf.fill(0)` to initialize a Buffer to zeroes.
+
+(Emphasis our own.)
+
+Whenever the programmer intended to create an uninitialized `Buffer` you often see code
+like this:
+
+```js
+var buf = new Buffer(16)
+
+// Immediately overwrite the uninitialized buffer with data from another buffer
+for (var i = 0; i < buf.length; i++) {
+  buf[i] = otherBuf[i]
+}
+```
+
+
+### Would this ever be a problem in real code?
+
+Yes. It's surprisingly common to forget to check the type of your variables in a
+dynamically-typed language like JavaScript.
+
+Usually the consequences of assuming the wrong type is that your program crashes with an
+uncaught exception. But the failure mode for forgetting to check the type of arguments to
+the `Buffer` constructor is more catastrophic.
+
+Here's an example of a vulnerable service that takes a JSON payload and converts it to
+hex:
+
+```js
+// Take a JSON payload {str: "some string"} and convert it to hex
+var server = http.createServer(function (req, res) {
+  var data = ''
+  req.setEncoding('utf8')
+  req.on('data', function (chunk) {
+    data += chunk
+  })
+  req.on('end', function () {
+    var body = JSON.parse(data)
+    res.end(new Buffer(body.str).toString('hex'))
+  })
+})
+
+server.listen(8080)
+```
+
+In this example, an http client just has to send:
+
+```json
+{
+  "str": 1000
+}
+```
+
+and it will get back 1,000 bytes of uninitialized memory from the server.
+
+This is a very serious bug. It's similar in severity to the
+[the Heartbleed bug](http://heartbleed.com/) that allowed disclosure of OpenSSL process
+memory by remote attackers.
+
+
+### Which real-world packages were vulnerable?
+
+#### [`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht)
+
+[Mathias Buus](https://github.com/mafintosh) and I
+([Feross Aboukhadijeh](http://feross.org/)) found this issue in one of our own packages,
+[`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht). The bug would allow
+anyone on the internet to send a series of messages to a user of `bittorrent-dht` and get
+them to reveal 20 bytes at a time of uninitialized memory from the node.js process.
+
+Here's
+[the commit](https://github.com/feross/bittorrent-dht/commit/6c7da04025d5633699800a99ec3fbadf70ad35b8)
+that fixed it. We released a new fixed version, created a
+[Node Security Project disclosure](https://nodesecurity.io/advisories/68), and deprecated all
+vulnerable versions on npm so users will get a warning to upgrade to a newer version.
+
+#### [`ws`](https://www.npmjs.com/package/ws)
+
+That got us wondering if there were other vulnerable packages. Sure enough, within a short
+period of time, we found the same issue in [`ws`](https://www.npmjs.com/package/ws), the
+most popular WebSocket implementation in node.js.
+
+If certain APIs were called with `Number` parameters instead of `String` or `Buffer` as
+expected, then uninitialized server memory would be disclosed to the remote peer.
+
+These were the vulnerable methods:
+
+```js
+socket.send(number)
+socket.ping(number)
+socket.pong(number)
+```
+
+Here's a vulnerable socket server with some echo functionality:
+
+```js
+server.on('connection', function (socket) {
+  socket.on('message', function (message) {
+    message = JSON.parse(message)
+    if (message.type === 'echo') {
+      socket.send(message.data) // send back the user's message
+    }
+  })
+})
+```
+
+`socket.send(number)` called on the server, will disclose server memory.
+
+Here's [the release](https://github.com/websockets/ws/releases/tag/1.0.1) where the issue
+was fixed, with a more detailed explanation. Props to
+[Arnout Kazemier](https://github.com/3rd-Eden) for the quick fix. Here's the
+[Node Security Project disclosure](https://nodesecurity.io/advisories/67).
+
+
+### What's the solution?
+
+It's important that node.js offers a fast way to get memory otherwise performance-critical
+applications would needlessly get a lot slower.
+
+But we need a better way to *signal our intent* as programmers. **When we want
+uninitialized memory, we should request it explicitly.**
+
+Sensitive functionality should not be packed into a developer-friendly API that loosely
+accepts many different types. This type of API encourages the lazy practice of passing
+variables in without checking the type very carefully.
+
+#### A new API: `Buffer.allocUnsafe(number)`
+
+The functionality of creating buffers with uninitialized memory should be part of another
+API. We propose `Buffer.allocUnsafe(number)`. This way, it's not part of an API that
+frequently gets user input of all sorts of different types passed into it.
+
+```js
+var buf = Buffer.allocUnsafe(16) // careful, uninitialized memory!
+
+// Immediately overwrite the uninitialized buffer with data from another buffer
+for (var i = 0; i < buf.length; i++) {
+  buf[i] = otherBuf[i]
+}
+```
+
+
+### How do we fix node.js core?
+
+We sent [a PR to node.js core](https://github.com/nodejs/node/pull/4514) (merged as
+`semver-major`) which defends against one case:
+
+```js
+var str = 16
+new Buffer(str, 'utf8')
+```
+
+In this situation, it's implied that the programmer intended the first argument to be a
+string, since they passed an encoding as a second argument. Today, node.js will allocate
+uninitialized memory in the case of `new Buffer(number, encoding)`, which is probably not
+what the programmer intended.
+
+But this is only a partial solution, since if the programmer does `new Buffer(variable)`
+(without an `encoding` parameter) there's no way to know what they intended. If `variable`
+is sometimes a number, then uninitialized memory will sometimes be returned.
+
+### What's the real long-term fix?
+
+We could deprecate and remove `new Buffer(number)` and use `Buffer.allocUnsafe(number)` when
+we need uninitialized memory. But that would break 1000s of packages.
+
+~~We believe the best solution is to:~~
+
+~~1. Change `new Buffer(number)` to return safe, zeroed-out memory~~
+
+~~2. Create a new API for creating uninitialized Buffers. We propose: `Buffer.allocUnsafe(number)`~~
+
+#### Update
+
+We now support adding three new APIs:
+
+- `Buffer.from(value)` - convert from any type to a buffer
+- `Buffer.alloc(size)` - create a zero-filled buffer
+- `Buffer.allocUnsafe(size)` - create an uninitialized buffer with given size
+
+This solves the core problem that affected `ws` and `bittorrent-dht` which is
+`Buffer(variable)` getting tricked into taking a number argument.
+
+This way, existing code continues working and the impact on the npm ecosystem will be
+minimal. Over time, npm maintainers can migrate performance-critical code to use
+`Buffer.allocUnsafe(number)` instead of `new Buffer(number)`.
+
+
+### Conclusion
+
+We think there's a serious design issue with the `Buffer` API as it exists today. It
+promotes insecure software by putting high-risk functionality into a convenient API
+with friendly "developer ergonomics".
+
+This wasn't merely a theoretical exercise because we found the issue in some of the
+most popular npm packages.
+
+Fortunately, there's an easy fix that can be applied today. Use `safe-buffer` in place of
+`buffer`.
+
+```js
+var Buffer = require('safe-buffer').Buffer
+```
+
+Eventually, we hope that node.js core can switch to this new, safer behavior. We believe
+the impact on the ecosystem would be minimal since it's not a breaking change.
+Well-maintained, popular packages would be updated to use `Buffer.alloc` quickly, while
+older, insecure packages would magically become safe from this attack vector.

+
+## Overview
+
+Provides a Node.js generator to produce Dockerfiles and related files.  It is intended to support any framework that lists its dependencies, includes a `start` script in `package.json`, and optionally includes a `build` script.
+
+See [test](./test) for a list of frameworks and examples of Dockerfiles produced based on the associated `package.json` and lock files.
+
+See [blog post](https://fly.io/blog/flydotio-heart-js/) for more information.
+
+## Usage
+
+To run once:
+
+```
+npx --yes @flydotio/dockerfile@latest
+```
+
+Or install it with your favorite package manager:
+
+```
+npm install @flydotio/dockerfile --save-dev
+pnpm add -D @flydotio/dockerfile
+yarn add @flydotio/dockerfile --dev
+```
+
+Once installed, you can run and re-run using:
+
+```
+npx dockerfile
+```
+
+Options are saved between runs into `package.json`. To invert a boolean options, add or remove a no- prefix from the option name.
+
+### Options:
+
+* `--ignore-scripts` - do not execute any scripts defined in the project `package.json` and its dependencies.
+* `--force` - overwrite existing files
+* `--legacy-peer-deps` - [ignore peer dependencies](https://docs.npmjs.com/cli/v7/using-npm/config#legacy-peer-deps).
+* `--swap=n` - allocate swap space.  See [falloc options](https://man7.org/linux/man-pages/man1/fallocate.1.html#OPTIONS) for suffixes
+* `--windows` - make Dockerfile work for Windows users that may have set `git config --global core.autocrlf true`.
+
+## Testing
+
+A single invocation of `npm test` will run all of the tests defined.  Additionally `npm run eslint` will run eslint.
+
+The current integration testing strategy is to run the dockerfile generator against various configurations and compare the generated artifacts with expected results.  `ARG` values in `Dockerfiles` are masked before comparison.
+
+To assis with this process, outputs of tests can be captured automatically.  This is useful when adding new tests and when making a change that affects many tests.  Be sure to inspect the output (e.g., by using `git diff`) before committing.
+
+```
+npm run test:capture
+```
+
+Additionally, each the outputs in each test directory can be directly tested to ensure that they can be successfully built by running docker buildx directory passing in the necessary build arguments.  For example:
+
+```
+docker buildx build . --build-arg NODE_VERSION=18
+```

+## Highlights
+
+- Expressive API
+- Highly performant
+- No dependencies
+- Ability to nest styles
+- [256/Truecolor color support](#256-and-truecolor-color-support)
+- Auto-detects color support
+- Doesn't extend `String.prototype`
+- Clean and focused
+- Actively maintained
+- [Used by ~86,000 packages](https://www.npmjs.com/browse/depended/chalk) as of October 4, 2022
+
+## Install
+
+```sh
+npm install chalk
+```
+
+**IMPORTANT:** Chalk 5 is ESM. If you want to use Chalk with TypeScript or a build tool, you will probably want to use Chalk 4 for now. [Read more.](https://github.com/chalk/chalk/releases/tag/v5.0.0)
+
+## Usage
+
+```js
+import chalk from 'chalk';
+
+console.log(chalk.blue('Hello world!'));
+```
+
+Chalk comes with an easy to use composable API where you just chain and nest the styles you want.
+
+```js
+import chalk from 'chalk';
+
+const log = console.log;
+
+// Combine styled and normal strings
+log(chalk.blue('Hello') + ' World' + chalk.red('!'));
+
+// Compose multiple styles using the chainable API
+log(chalk.blue.bgRed.bold('Hello world!'));
+
+// Pass in multiple arguments
+log(chalk.blue('Hello', 'World!', 'Foo', 'bar', 'biz', 'baz'));
+
+// Nest styles
+log(chalk.red('Hello', chalk.underline.bgBlue('world') + '!'));
+
+// Nest styles of the same type even (color, underline, background)
+log(chalk.green(
+	'I am a green line ' +
+	chalk.blue.underline.bold('with a blue substring') +
+	' that becomes green again!'
+));
+
+// ES2015 template literal
+log(`
+CPU: ${chalk.red('90%')}
+RAM: ${chalk.green('40%')}
+DISK: ${chalk.yellow('70%')}
+`);
+
+// Use RGB colors in terminal emulators that support it.
+log(chalk.rgb(123, 45, 67).underline('Underlined reddish color'));
+log(chalk.hex('#DEADED').bold('Bold gray!'));
+```
+
+Easily define your own themes:
+
+```js
+import chalk from 'chalk';
+
+const error = chalk.bold.red;
+const warning = chalk.hex('#FFA500'); // Orange color
+
+console.log(error('Error!'));
+console.log(warning('Warning!'));
+```
+
+Take advantage of console.log [string substitution](https://nodejs.org/docs/latest/api/console.html#console_console_log_data_args):
+
+```js
+import chalk from 'chalk';
+
+const name = 'Sindre';
+console.log(chalk.green('Hello %s'), name);
+//=> 'Hello Sindre'
+```
+
+## API
+
+### chalk.`<style>[.<style>...](string, [string...])`
+
+Example: `chalk.red.bold.underline('Hello', 'world');`
+
+Chain [styles](#styles) and call the last one as a method with a string argument. Order doesn't matter, and later styles take precedent in case of a conflict. This simply means that `chalk.red.yellow.green` is equivalent to `chalk.green`.
+
+Multiple arguments will be separated by space.
+
+### chalk.level
+
+Specifies the level of color support.
+
+Color support is automatically detected, but you can override it by setting the `level` property. You should however only do this in your own code as it applies globally to all Chalk consumers.
+
+If you need to change this in a reusable module, create a new instance:
+
+```js
+import {Chalk} from 'chalk';
+
+const customChalk = new Chalk({level: 0});
+```
+
+| Level | Description |
+| :---: | :--- |
+| `0` | All colors disabled |
+| `1` | Basic color support (16 colors) |
+| `2` | 256 color support |
+| `3` | Truecolor support (16 million colors) |
+
+### supportsColor
+
+Detect whether the terminal [supports color](https://github.com/chalk/supports-color). Used internally and handled for you, but exposed for convenience.
+
+Can be overridden by the user with the flags `--color` and `--no-color`. For situations where using `--color` is not possible, use the environment variable `FORCE_COLOR=1` (level 1), `FORCE_COLOR=2` (level 2), or `FORCE_COLOR=3` (level 3) to forcefully enable color, or `FORCE_COLOR=0` to forcefully disable. The use of `FORCE_COLOR` overrides all other color support checks.
+
+Explicit 256/Truecolor mode can be enabled using the `--color=256` and `--color=16m` flags, respectively.
+
+### chalkStderr and supportsColorStderr
+
+`chalkStderr` contains a separate instance configured with color support detected for `stderr` stream instead of `stdout`. Override rules from `supportsColor` apply to this too. `supportsColorStderr` is exposed for convenience.
+
+### modifierNames, foregroundColorNames, backgroundColorNames, and colorNames
+
+All supported style strings are exposed as an array of strings for convenience. `colorNames` is the combination of `foregroundColorNames` and `backgroundColorNames`.
+
+This can be useful if you wrap Chalk and need to validate input:
+
+```js
+import {modifierNames, foregroundColorNames} from 'chalk';
+
+console.log(modifierNames.includes('bold'));
+//=> true
+
+console.log(foregroundColorNames.includes('pink'));
+//=> false
+```
+
+## Styles
+
+### Modifiers
+
+- `reset` - Reset the current style.
+- `bold` - Make the text bold.
+- `dim` - Make the text have lower opacity.
+- `italic` - Make the text italic. *(Not widely supported)*
+- `underline` - Put a horizontal line below the text. *(Not widely supported)*
+- `overline` - Put a horizontal line above the text. *(Not widely supported)*
+- `inverse`- Invert background and foreground colors.
+- `hidden` - Print the text but make it invisible.
+- `strikethrough` - Puts a horizontal line through the center of the text. *(Not widely supported)*
+- `visible`- Print the text only when Chalk has a color level above zero. Can be useful for things that are purely cosmetic.
+

+
+## 256 and Truecolor color support
+
+Chalk supports 256 colors and [Truecolor](https://github.com/termstandard/colors) (16 million colors) on supported terminal apps.
+
+Colors are downsampled from 16 million RGB values to an ANSI color format that is supported by the terminal emulator (or by specifying `{level: n}` as a Chalk option). For example, Chalk configured to run at level 1 (basic color support) will downsample an RGB value of #FF0000 (red) to 31 (ANSI escape for red).
+
+Examples:
+
+- `chalk.hex('#DEADED').underline('Hello, world!')`
+- `chalk.rgb(15, 100, 204).inverse('Hello!')`
+
+Background versions of these models are prefixed with `bg` and the first level of the module capitalized (e.g. `hex` for foreground colors and `bgHex` for background colors).
+
+- `chalk.bgHex('#DEADED').underline('Hello, world!')`
+- `chalk.bgRgb(15, 100, 204).inverse('Hello!')`
+
+The following color models can be used:
+
+- [`rgb`](https://en.wikipedia.org/wiki/RGB_color_model) - Example: `chalk.rgb(255, 136, 0).bold('Orange!')`
+- [`hex`](https://en.wikipedia.org/wiki/Web_colors#Hex_triplet) - Example: `chalk.hex('#FF8800').bold('Orange!')`
+- [`ansi256`](https://en.wikipedia.org/wiki/ANSI_escape_code#8-bit) - Example: `chalk.bgAnsi256(194)('Honeydew, more or less')`
+
+## Browser support
+
+Since Chrome 69, ANSI escape codes are natively supported in the developer console.
+
+## Windows
+
+If you're on Windows, do yourself a favor and use [Windows Terminal](https://github.com/microsoft/terminal) instead of `cmd.exe`.
+
+## Origin story
+
+[colors.js](https://github.com/Marak/colors.js) used to be the most popular string styling module, but it has serious deficiencies like extending `String.prototype` which causes all kinds of [problems](https://github.com/yeoman/yo/issues/68) and the package is unmaintained. Although there are other packages, they either do too much or not enough. Chalk is a clean and focused alternative.

+# abbrev-js
+
+Just like [ruby's Abbrev](http://apidock.com/ruby/Abbrev).
+
+Usage:
+
+    var abbrev = require("abbrev");
+    abbrev("foo", "fool", "folding", "flop");
+    
+    // returns:
+    { fl: 'flop'
+    , flo: 'flop'
+    , flop: 'flop'
+    , fol: 'folding'
+    , fold: 'folding'
+    , foldi: 'folding'
+    , foldin: 'folding'
+    , folding: 'folding'
+    , foo: 'foo'
+    , fool: 'fool'
+    }
+
+This is handy for command-line scripts, or other cases where you want to be able to accept shorthands.

+
+Higher level content negotiation based on [negotiator](https://www.npmjs.com/package/negotiator).
+Extracted from [koa](https://www.npmjs.com/package/koa) for general use.
+
+In addition to negotiator, it allows:
+
+- Allows types as an array or arguments list, ie `(['text/html', 'application/json'])`
+  as well as `('text/html', 'application/json')`.
+- Allows type shorthands such as `json`.
+- Returns `false` when no types match
+- Treats non-existent headers as `*`
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install accepts
+```
+
+## API
+
+```js
+var accepts = require('accepts')
+```
+
+### accepts(req)
+
+Create a new `Accepts` object for the given `req`.
+
+#### .charset(charsets)
+
+Return the first accepted charset. If nothing in `charsets` is accepted,
+then `false` is returned.
+
+#### .charsets()
+
+Return the charsets that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .encoding(encodings)
+
+Return the first accepted encoding. If nothing in `encodings` is accepted,
+then `false` is returned.
+
+#### .encodings()
+
+Return the encodings that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .language(languages)
+
+Return the first accepted language. If nothing in `languages` is accepted,
+then `false` is returned.
+
+#### .languages()
+
+Return the languages that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .type(types)
+
+Return the first accepted type (and it is returned as the same text as what
+appears in the `types` array). If nothing in `types` is accepted, then `false`
+is returned.
+
+The `types` array can contain full MIME types or file extensions. Any value
+that is not a full MIME types is passed to `require('mime-types').lookup`.
+
+#### .types()
+
+Return the types that the request accepts, in the order of the client's
+preference (most preferred first).
+
+## Examples
+
+### Simple type negotiation
+
+This simple example shows how to use `accepts` to return a different typed
+respond body based on what the client wants to accept. The server lists it's
+preferences in order and will get back the best match between the client and
+server.
+
+```js
+var accepts = require('accepts')
+var http = require('http')
+
+function app (req, res) {
+  var accept = accepts(req)
+
+  // the order of this list is significant; should be server preferred order
+  switch (accept.type(['json', 'html'])) {
+    case 'json':
+      res.setHeader('Content-Type', 'application/json')
+      res.write('{"hello":"world!"}')
+      break
+    case 'html':
+      res.setHeader('Content-Type', 'text/html')
+      res.write('<b>hello, world!</b>')
+      break
+    default:
+      // the fallback is text/plain, so no need to specify it above
+      res.setHeader('Content-Type', 'text/plain')
+      res.write('hello, world!')
+      break
+  }
+
+  res.end()
+}
+
+http.createServer(app).listen(3000)
+```
+
+You can test this out with the cURL program:
+```sh
+curl -I -H'Accept: text/html' http://localhost:3000/
+```
