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
```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.
#### 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)`.
```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 red for server error codes, yellow for client error
codes, cyan for redirection codes, and uncolored for all other 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:
```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.
##### :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 version 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.
##### :res[header]
The given `header` of the response.
##### :response-time
The time between the request coming into `morgan` and when the response headers are written, in milliseconds.
##### :status
The status code of the response.
##### :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.
## 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 app = express()
// create a write stream (in append mode)
var accessLogStream = fs.createWriteStream(__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 date in the `log/` directory using the
[file-stream-rotator module](https://www.npmjs.com/package/file-stream-rotator).
```js
var FileStreamRotator = require('file-stream-rotator')
var express = require('express')
var fs = require('fs')
var morgan = require('morgan')
var app = express()
var logDirectory = __dirname + '/log'
// ensure log directory exists
fs.existsSync(logDirectory) || fs.mkdirSync(logDirectory)
// create a rotating write stream
var accessLogStream = FileStreamRotator.getStream({
filename: logDirectory + '/access-%DATE%.log',
frequency: 'daily',
verbose: false
})
// setup the logger
app.use(morgan('combined', {stream: accessLogStream}))
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()
}
```

# basic-auth

[![NPM Downloads][downloads-image]][downloads-url]
[![Node.js Version][node-version-image]][node-version-url]
[![Build Status][travis-image]][travis-url]

Generic basic auth Authorization header field parser for whatever.
## Installation
```
$ npm install basic-auth
```
## API
```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.
## Example
Pass a node request or koa Context object to the module exported. If
parsing fails `undefined` is returned, otherwise an object with
`.name` and `.pass`.
```js
var auth = require('basic-auth');
var user = auth(req);
// => { name: 'something', pass: 'whatever' }
```
### With vanilla node.js http server
```js
var http = require('http')
var auth = require('basic-auth')
// Create server
var server = http.createServer(function (req, res) {
var credentials = auth(req)
if (!credentials || credentials.name !== 'john' || credentials.pass !== 'secret') {
res.statusCode = 401
res.setHeader('WWW-Authenticate', 'Basic realm="example"')
res.end('Access denied')
} else {
res.end('Access granted')
}
})
// Listen
server.listen(3000)
```

Deprecate all the things
> With great modules comes great responsibility; mark things deprecated!
## Install
```sh
$ npm install depd
```
## API
```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
| | | |
▼ ▼ ▼ ▼
my-cool-module deprecated oldfunction [eval]-wrapper:6:22
▲ ▲ ▲ ▲
| | | |
namespace | | location of mycoolmod.oldfunction() call
| deprecation message
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):
```
Sun, 15 Jun 2014 05:21:37 GMT my-cool-module deprecated oldfunction at [eval]-wrapper:6:22
▲ ▲ ▲ ▲ ▲
| | | | |
timestamp of message namespace | | location of mycoolmod.oldfunction() call
| deprecation message
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')
```

# on-finished
[![NPM Version][npm-image]][npm-url]
[![NPM Downloads][downloads-image]][downloads-url]
[![Node.js Version][node-version-image]][node-version-url]
[![Build Status][travis-image]][travis-url]
[![Test Coverage][coveralls-image]][coveralls-url]
Execute a callback when a 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 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 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.
### 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)
})
})
```

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()

The listener will\nbe invoked only once when the response finished. If the response finished\nto to an error, the first argument will contain the error. If the response\nhas already finished, the listener will be invoked.\n\nListening to the end of a response would be used to close things associated\nwith the response, like open files.\n\nListener is invoked as `listener(err, res)`.\n\n```js\nonFinished(res, function (err, res) {\n // clean up open fds, etc.\n // err contains the error is request error'd\n})\n```\n\n### onFinished(req, listener)\n\nAttach a listener to listen for the request to finish. The listener will\nbe invoked only once when the request finished. If the request finished\nto to an error, the first argument will contain the error. If the request\nhas already finished, the listener will be invoked.\n\nListening to the end of a request would be used to know when to continue\nafter reading the data.\n\nListener is invoked as `listener(err, req)`.\n\n```js\nvar data = ''\n\nreq.setEncoding('utf8')\nres.on('data', function (str) {\n data += str\n})\n\nonFinished(req, function (err, req) {\n // data is read unless there is err\n})\n```\n\n### onFinished.isFinished(res)\n\nDetermine if `res` is already finished. This would be useful to check and\nnot even start certain operations if the response has already finished.\n\n### onFinished.isFinished(req)\n\nDetermine if `req` is already finished. This would be useful to check and\nnot even start certain operations if the request has already finished.\n\n### Example\n\nThe following code ensures that file descriptors are always closed\nonce the response finishes.\n\n```js\nvar destroy = require('destroy')\nvar http = require('http')\nvar onFinished = require('on-finished')\n\nhttp.createServer(function onRequest(req, res) {\n var stream = fs.createReadStream('package.json')\n stream.pipe(res)\n onFinished(res, function (err) {\n destroy(stream)\n })\n})\n```\n\n## License\n\n[MIT](LICENSE)\n\n[npm-image]: https://img.shields.io/npm/v/on-finished.svg\n[npm-url]: https://npmjs.org/package/on-finished\n[node-version-image]: https://img.shields.io/node/v/on-finished.svg\n[node-version-url]: http://nodejs.org/download/\n[travis-image]: https://img.shields.io/travis/jshttp/on-finished/master.svg\n[travis-url]: https://travis-ci.org/jshttp/on-finished\n[coveralls-image]: https://img.shields.io/coveralls/jshttp/on-finished/master.svg\n[coveralls-url]: https://coveralls.io/r/jshttp/on-finished?branch=master\n[downloads-image]: https://img.shields.io/npm/dm/on-finished.svg\n[downloads-url]: https://npmjs.org/package/on-finished\n",
