For example, the following creates an Express app named myapp in the current working directory:

$ express myapp

   create : myapp
   create : myapp/package.json
   create : myapp/app.js
   create : myapp/public
   create : myapp/public/javascripts
   create : myapp/public/images
   create : myapp/routes
   create : myapp/routes/index.js
   create : myapp/routes/users.js
   create : myapp/public/stylesheets
   create : myapp/public/stylesheets/style.css
   create : myapp/views
   create : myapp/views/index.jade
   create : myapp/views/layout.jade
   create : myapp/views/error.jade
   create : myapp/bin
   create : myapp/bin/www

Then install dependencies:

$ cd myapp
$ npm install

On MacOS or Linux, run the app with this command:

$ DEBUG=myapp:* npm start

On Windows, use this command:

> set DEBUG=myapp:* & npm start

Then load http://localhost:3000/ in your browser to access the app.
The generated app has the following directory structure:
