PROTIP Be sure to read Migrating from 3.x to 4.x as well as New features in 4.x.
The quickest way to get started with express is to utilize the executable express(1) to generate an application as shown below:
Install the executable. The executable's major version will match Express's:
$ npm install -g express-generator@4Create the app:
$ express /tmp/foo && cd /tmp/fooInstall dependencies:
$ npm installStart the server:
$ npm startThe 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.
Express does not force you to use any specific ORM or template engine. With support for over 14 template engines via Consolidate.js, you can quickly craft your perfect framework.
To view the examples, clone the Express repo and install the dependancies:
$ git clone git://github.com/strongloop/express.git --depth 1
$ cd express
$ npm installThen run whichever example you want:
$ node examples/content-negotiationTo run the test suite, first install the dependencies, then run npm test:
$ npm install
$ npm testThe original author of Express is TJ Holowaychuk
The current lead maintainer is Douglas Christopher Wilson
