    Security Issues

    If you discover a security vulnerability in Express, please see Security Policies and Procedures.

    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 and install the dependencies:

    $ git clone git://github.com/expressjs/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 dependencies, then run npm test:

    $ npm install
    $ npm test
