**PROTIP** Be sure to read [Migrating from 3.x to 4.x](https://github.com/expressjs/express/wiki/Migrating-from-3.x-to-4.x) as well as [New features in 4.x](https://github.com/expressjs/express/wiki/New-features-in-4.x).
|
|
|
|
## Quick Start
|
|
|
|
The quickest way to get started with express is to utilize the executable [`express(1)`](https://github.com/expressjs/generator) to generate an application as shown below:
|
|
|
|
Install the executable. The executable's major version will match Express's:
|
|
|
|
```console
|
|
$ npm install -g express-generator@4
|
|
```
|
|
|
|
Create the app:
|
|
|
|
```console
|
|
$ express /tmp/foo && cd /tmp/foo
|
|
```
|
|
|
|
Install dependencies:
|
|
|
|
```console
|
|
$ npm install
|
|
```
|
|
|
|
Start the server:
|
|
|
|
```console
|
|
$ npm start
|
|
```
|
|
|
|
View the website at: http://localhost:3000
|
|
|
|
## Philosophy
|
|
|
|
The Express philosophy is to provide small, robust tooling for HTTP servers, making
|
|
it a great solution for single page applications, websites, hybrids, or public
|
|
HTTP APIs.
|
|
|
|
Express does not force you to use any specific ORM or template engine. With support for over
|
|
14 template engines via [Consolidate.js](https://github.com/tj/consolidate.js),
|
|
you can quickly craft your perfect framework.
|
|
|
|
## Examples
|
|
|
|
To view the examples, clone the Express repo and install the dependencies:
|
|
|
|
```console
|
|
$ git clone https://github.com/expressjs/express.git --depth 1
|
|
$ cd express
|
|
$ npm install
|
|
```
|
|
|
|
Then run whichever example you want:
|
|
|
|
```console
|
|
$ node examples/content-negotiation
|
|
```
