    Quick Start

    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@4

    Create the app:

    $ express /tmp/foo && cd /tmp/foo

    Install dependencies:

    $ npm install

    Start the server:

    $ npm start

    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.

    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.

    Examples

    To view the examples, clone the Express repo & install the dependancies:

    $ git clone git://github.com/strongloop/express.git --depth 1
    $ cd express
    $ npm install

    Then run whichever example you want:

    $ node examples/content-negotiation

    Tests

    To run the test suite, first install the dependancies, then run npm test:

    $ npm install
    $ npm test
