Here is the full description to create the first program using the express generator,
Ubuntu's package manager
To install Node.js and npm via apt-get, run these commands:
sudo apt-get update
sudo apt-get install nodejs
sudo ln -s /usr/bin/nodejs /usr/bin/node
sudo apt-get install npm
Express application generator:
$ npm install express-generator -g
Display the command options with the -h option:
$ express -h
Usage: express [options] [dir]
Options:
-h, --help output usage information
-V, --version output the version number
-e, --ejs add ejs engine support (defaults to jade)
--hbs add handlebars engine support
-H, --hogan add hogan.js engine support
-c, --css <engine> add stylesheet <engine> support (less|stylus|compass|sass) (defaults to plain css)
--git add .gitignore
-f, --force force on non-empty directory
For example, the following creates an Express application 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
Run the app with this command:
$ DEBUG=myapp:* npm start
Then load http://localhost:3000/ in your browser to access the application.
The generated application has the following directory structure:
+-- app.js
+-- bin
¦ +-- www
+-- package.json
+-- public
¦ +-- images
¦ +-- javascripts
¦ +-- stylesheets
¦ +-- style.css
+-- routes
¦ +-- index.js
¦ +-- users.js
+-- views
+-- error.jade
+-- index.jade
+-- layout.jade
