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

View the website at: http://localhost:3000

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 @ladjs/consolidate, you can quickly craft your perfect framework.

To view the examples, clone the Express repository:

git clone https://github.com/expressjs/express.git --depth 1 && cd express

Then install the dependencies:

npm install

Then run whichever example you want:

node examples/content-negotiation
