Fast, unopinionated, minimalist web framework for [node](http://nodejs.org). [![Build Status](https://secure.travis-ci.org/visionmedia/express.png)](http://travis-ci.org/visionmedia/express)
```js
var express = require('express');
var app = express();
app.get('/', function(req, res){
res.send('Hello World');
});
app.listen(3000);
```
## Installation
$ npm install -g express
## Quick Start
The quickest way to get started with express is to utilize the executable `express(1)` to generate an application as shown below:
Create the app:
$ npm install -g express
$ express /tmp/foo && cd /tmp/foo
Install dependencies:
$ npm install
Start the server:
$ node app
## Features
* Built on [Connect](http://github.com/senchalabs/connect)
* Robust routing
* HTTP helpers (redirection, caching, etc)
* View system supporting 14+ template engines
* Content negotiation
* Focus on high performance
* Environment based configuration
* Executable for generating applications quickly
* High test coverage
## Philosophy
The Express philosophy is to provide small, robust tooling for HTTP servers. Making
it a great solution for single page applications, web sites, hybrids, or public
HTTP APIs.
Built on Connect you can use _only_ what you need, and nothing more, applications
can be as big or as small as you like, even a single file. Express does
not force you to use any specific ORM or template engine. With support for over
14 template engines via [Consolidate.js](http://github.com/visionmedia/consolidate.js)
you can quickly craft your perfect framework.
## More Information
* Join #express on freenode
* [Google Group](http://groups.google.com/group/express-js) for discussion
* Follow [tjholowaychuk](http://twitter.com/tjholowaychuk) on twitter for updates
* Visit the [Wiki](http://github.com/visionmedia/express/wiki)
* [日本語ドキュメンテーション](http://hideyukisaito.com/doc/expressjs/) by [hideyukisaito](https://github.com/hideyukisaito)
* [Русскоязычная документация](http://express-js.ru/)
## Viewing Examples
Clone the Express repo, then install the dev dependencies to install all the example / test suite deps:
$ git clone git://github.com/visionmedia/express.git --depth 1
$ cd express
$ npm install
then run whichever tests you want:
$ node examples/content-negotiation
## Running Tests
To run the test suite first invoke the following command within the repo, installing the development dependencies:
$ npm install
then run the tests:
$ make test

# buffer-crc32
[![Build Status](https://secure.travis-ci.org/brianloveswords/buffer-crc32.png?branch=master)](http://travis-ci.org/brianloveswords/buffer-crc32)
crc32 that works with binary data and fancy character sets, outputs
buffer, signed or unsigned data and has tests.
Derived from the sample CRC implementation in the PNG specification: http://www.w3.org/TR/PNG/#D-CRCAppendix
# install
```
npm install buffer-crc32
```
# example
```js
var crc32 = require('buffer-crc32');
// works with buffers
var buf = Buffer([[0x00, 0x73, 0x75, 0x70, 0x20, 0x62, 0x72, 0x6f, 0x00])
crc32(buf) // -> <Buffer 94 5a ab 4a>
// has convenience methods for getting signed or unsigned ints
crc32.signed(buf) // -> -1805997238
crc32.unsigned(buf) // -> 2488970058
// will cast to buffer if given a string, so you can
// directly use foreign characters safely
crc32('自動販売機') // -> <Buffer cb 03 1a c5>
```
# tests
This was tested against the output of zlib's crc32 method. You can run
the tests with`npm test` (requires tap)

# Commander.js
The complete solution for [node.js](http://nodejs.org) command-line interfaces, inspired by Ruby's [commander](https://github.com/visionmedia/commander).
[![Build Status](https://secure.travis-ci.org/visionmedia/commander.js.png)](http://travis-ci.org/visionmedia/commander.js)
## Installation
$ npm install commander
## Option parsing
Options with commander are defined with the `.option()` method, also serving as documentation for the options. The example below parses args and options from `process.argv`, leaving remaining args as the `program.args` array which were not consumed by options.
```js
#!/usr/bin/env node
/**
* Module dependencies.
*/
var program = require('commander');
program
.version('0.0.1')
.option('-p, --peppers', 'Add peppers')
.option('-P, --pineapple', 'Add pineapple')
.option('-b, --bbq', 'Add bbq sauce')
.option('-c, --cheese [type]', 'Add the specified type of cheese [marble]', 'marble')
.parse(process.argv);
console.log('you ordered a pizza with:');
if (program.peppers) console.log(' - peppers');
if (program.pineapple) console.log(' - pineappe');
if (program.bbq) console.log(' - bbq');
console.log(' - %s cheese', program.cheese);
```
Short flags may be passed as a single arg, for example `-abc` is equivalent to `-a -b -c`. Multi-word options such as "--template-engine" are camel-cased, becoming `program.templateEngine` etc.
## Automated --help
The help information is auto-generated based on the information commander already knows about your program, so the following `--help` info is for free:
```
$ ./examples/pizza --help
Usage: pizza [options]
Options:
-V, --version output the version number
-p, --peppers Add peppers
-P, --pineapple Add pineappe
-b, --bbq Add bbq sauce
-c, --cheese <type> Add the specified type of cheese [marble]
-h, --help output usage information
```
## Coercion
```js
function range(val) {
return val.split('..').map(Number);
}
function list(val) {
return val.split(',');
}
program
.version('0.0.1')
.usage('[options] <file ...>')
.option('-i, --integer <n>', 'An integer argument', parseInt)
.option('-f, --float <n>', 'A float argument', parseFloat)
.option('-r, --range <a>..<b>', 'A range', range)
.option('-l, --list <items>', 'A list', list)
.option('-o, --optional [value]', 'An optional value')
.parse(process.argv);
console.log(' int: %j', program.integer);
console.log(' float: %j', program.float);
console.log(' optional: %j', program.optional);
program.range = program.range || [];
console.log(' range: %j..%j', program.range[0], program.range[1]);
console.log(' list: %j', program.list);
console.log(' args: %j', program.args);
```
## Custom help
You can display arbitrary `-h, --help` information
by listening for "--help". Commander will automatically
exit once you are done so that the remainder of your program
does not execute causing undesired behaviours, for example
in the following executable "stuff" will not output when
`--help` is used.
```js
#!/usr/bin/env node
/**
* Module dependencies.
*/
var program = require('../');
function list(val) {
return val.split(',').map(Number);
}
program
.version('0.0.1')
.option('-f, --foo', 'enable some foo')
.option('-b, --bar', 'enable some bar')
.option('-B, --baz', 'enable some baz');
// must be before .parse() since
// node's emit() is immediate
program.on('--help', function(){
console.log(' Examples:');
console.log('');
console.log(' $ custom-help --help');
console.log(' $ custom-help -h');
console.log('');
});
program.parse(process.argv);
console.log('stuff');
```
yielding the following help output:
```
Usage: custom-help [options]
Options:
-h, --help output usage information
-V, --version output the version number
-f, --foo enable some foo
-b, --bar enable some bar
-B, --baz enable some baz
Examples:
$ custom-help --help
$ custom-help -h
```
## .prompt(msg, fn)
Single-line prompt:
```js
program.prompt('name: ', function(name){
console.log('hi %s', name);
});
```
Multi-line prompt:
```js
program.prompt('description:', function(name){
console.log('hi %s', name);
});
```
Coercion:
```js
program.prompt('Age: ', Number, function(age){
console.log('age: %j', age);
});
```
```js
program.prompt('Birthdate: ', Date, function(date){
console.log('date: %s', date);
});
```
## .password(msg[, mask], fn)
Prompt for password without echoing:
```js
program.password('Password: ', function(pass){
console.log('got "%s"', pass);
process.stdin.destroy();
});
```
Prompt for password with mask char "*":
```js
program.password('Password: ', '*', function(pass){
console.log('got "%s"', pass);
process.stdin.destroy();
});
```
## .confirm(msg, fn)
Confirm with the given `msg`:
```js
program.confirm('continue? ', function(ok){
console.log(' got %j', ok);
});
```
## .choose(list, fn)
Let the user choose from a `list`:
```js
var list = ['tobi', 'loki', 'jane', 'manny', 'luna'];
console.log('Choose the coolest pet:');
program.choose(list, function(i){
console.log('you chose %d "%s"', i, list[i]);
});
```

* Logger:
*
* Log requests with the given `options` or a `format` string.
*
* Options:
*
* - `format` Format string, see below for tokens
* - `stream` Output stream, defaults to _stdout_
* - `buffer` Buffer duration, defaults to 1000ms when _true_
* - `immediate` Write log line on request instead of response (for response times)
*
* Tokens:
*
* - `:req[header]` ex: `:req[Accept]`
* - `:res[header]` ex: `:res[Content-Length]`
* - `:http-version`
* - `:response-time`

* - `tiny` ':method :url :status :res[content-length] - :response-time ms'
* - `dev` concise output colored by response status for development use
*
* Examples:
*
* connect.logger() // default
* connect.logger('short')
* connect.logger('tiny')
* connect.logger({ immediate: true, format: 'dev' })
* connect.logger(':method :url - :referrer')
* connect.logger(':req[content-type] -> :res[content-type]')
* connect.logger(function(tokens, req, res){ return 'some format string' })

*
* To define a token, simply invoke `connect.logger.token()` with the
* name and a callback function. The value returned is then available
* as ":type" in this case.
*
* connect.logger.token('type', function(req, res){ return req.headers['content-type']; })

* Session:
*
* Setup session store with the given `options`.
*
* Session data is _not_ saved in the cookie itself, however
* cookies are used, so we must use the [cookieParser()](cookieParser.html)
* middleware _before_ `session()`.
*
* Examples:
*
* connect()
* .use(connect.cookieParser())
* .use(connect.session({ secret: 'keyboard cat', key: 'sid', cookie: { secure: true }}))
*
* Options:
*
* - `key` cookie name defaulting to `connect.sid`
* - `store` session store instance
* - `secret` session cookie is signed with this secret to prevent tampering
* - `cookie` session cookie settings, defaulting to `{ path: '/', httpOnly: true, maxAge: null }`
* - `proxy` trust the reverse proxy when setting secure cookies (via "x-forwarded-proto")
*
* Cookie option:
*
* By default `cookie.maxAge` is `null`, meaning no "expires" parameter is set
* so the cookie becomes a browser-session cookie. When the user closes the
* browser the cookie (and session) will be removed.
*
* ## req.session
*
* To store or access session data, simply use the request property `req.session`,
* which is (generally) serialized as JSON by the store, so nested objects
* are typically fine. For example below is a user-specific view counter:
*
* connect()
* .use(connect.favicon())
* .use(connect.cookieParser())
* .use(connect.session({ secret: 'keyboard cat', cookie: { maxAge: 60000 }}))
* .use(function(req, res, next){
* var sess = req.session;
* if (sess.views) {
* res.setHeader('Content-Type', 'text/html');
* res.write('<p>views: ' + sess.views + '</p>');
* res.write('<p>expires in: ' + (sess.cookie.maxAge / 1000) + 's</p>');
* res.end();
* sess.views++;
* } else {
* sess.views = 1;
* res.end('welcome to the session demo. refresh!');
* }
* }
* )).listen(3000);
*
* ## Session#regenerate()
*
* To regenerate the session simply invoke the method, once complete
* a new SID and `Session` instance will be initialized at `req.session`.
*
* req.session.regenerate(function(err){
* // will have a new session here
* });
*
* ## Session#destroy()
*
* Destroys the session, removing `req.session`, will be re-generated next request.
*
* req.session.destroy(function(err){
* // cannot access session here
* });
*
* ## Session#reload()
*
* Reloads the session data.
*
* req.session.reload(function(err){
* // session updated
* });
*
* ## Session#save()
*
* Save the session.
*
* req.session.save(function(err){
* // session saved
* });
*
* ## Session#touch()
*
* Updates the `.maxAge` property. Typically this is
* not necessary to call, as the session middleware does this for you.
*
* ## Session#cookie
*
* Each session has a unique cookie object accompany it. This allows
* you to alter the session cookie per visitor. For example we can
* set `req.session.cookie.expires` to `false` to enable the cookie
* to remain for only the duration of the user-agent.
*
* ## Session#maxAge
*
* Alternatively `req.session.cookie.maxAge` will return the time
* remaining in milliseconds, which we may also re-assign a new value
* to adjust the `.expires` property appropriately. The following
* are essentially equivalent
*
* var hour = 3600000;
* req.session.cookie.expires = new Date(Date.now() + hour);
* req.session.cookie.maxAge = hour;
*
* For example when `maxAge` is set to `60000` (one minute), and 30 seconds
* has elapsed it will return `30000` until the current request has completed,
* at which time `req.session.touch()` is called to reset `req.session.maxAge`
* to its original value.
*
* req.session.cookie.maxAge;
* // => 30000
*
* Session Store Implementation:
*
* Every session store _must_ implement the following methods
*
* - `.get(sid, callback)`
* - `.set(sid, session, callback)`
* - `.destroy(sid, callback)`
*
* Recommended methods include, but are not limited to:
*
* - `.length(callback)`
* - `.clear(callback)`
*
* For an example implementation view the [connect-redis](http://github.com/visionmedia/connect-redis) repo.
