1# You can run the application generator with the npx command (available in Node.js 8.2.0).
2npx express-generator
3# For earlier Node versions, install the application generator as a global npm package and then launch it:
4npm install -g express-generator
5# For example, the following creates an Express app named myapp. The app will be created in a folder named myapp in the current working directory and the view engine will be set to Pug:
6express --view=pug myapp
7
8   create : myapp
9   create : myapp/package.json
10   create : myapp/app.js
11   create : myapp/public
12   create : myapp/public/javascripts
13   create : myapp/public/images
14   create : myapp/routes
15   create : myapp/routes/index.js
16   create : myapp/routes/users.js
17   create : myapp/public/stylesheets
18   create : myapp/public/stylesheets/style.css
19   create : myapp/views
20   create : myapp/views/index.pug
21   create : myapp/views/layout.pug
22   create : myapp/views/error.pug
23   create : myapp/bin
24   create : myapp/bin/www
25# Then install dependencies:
26cd myapp
27npm install
28# On MacOS or Linux, run the app with this command:
29DEBUG=myapp:* npm start
30# On Windows Command Prompt, use this command:
31set DEBUG=myapp:* & npm start
32# On Windows PowerShell, use this command:
33$env:DEBUG='myapp:*'; npm start
