|
|
Fast, unopinionated, minimalist web framework for [node](http://nodejs.org).
|
|
|
|
[](http://travis-ci.org/visionmedia/express) [](https://www.gittip.com/visionmedia/)
|
|
|
|
```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
|
|
|
|

## 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.
