Terminal window
npm install express-generator -g

The generator has a number of options, which you can view on the command line using the —help (or -h) command:

Terminal window
> express --help


    Usage: express [options] [dir]


  Options:


        --version        output the version number
    -e, --ejs            add ejs engine support
        --pug            add pug engine support
        --hbs            add handlebars engine support
    -H, --hogan          add hogan.js engine support
    -v, --view <engine>  add view <engine> support (dust|ejs|hbs|hjs|jade|pug|twig|vash) (defaults to jade)
        --no-view        use static html instead of view engine
    -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
    -h, --help           output usage information

You can specify express to create a project inside the current directory using the Jade view engine and plain CSS (if you specify a directory name then the project will be created in a sub-folder with that name).

Terminal window
express

see example below

Terminal window
express projectname --view=pug

After everything has been done

Terminal window
   change directory:
     > cd projectname


   install dependencies:
     > npm install


   run the app (Bash (Linux or macOS))
     > DEBUG=projectname:* npm start


   run the app (PowerShell (Windows))
     > $ENV:DEBUG = "projectname:*"; npm start


   run the app (Command Prompt (Windows)):
     > SET DEBUG=projectname:* & npm start
