Example 1: express

# You can run the application generator with the npx command (available in Node.js 8.2.0).
npx express-generator
# For earlier Node versions, install the application generator as a global npm package and then launch it:
npm install -g express-generator
# 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:
express --view=pug myapp

   create : myapp
   create : myapp/package.json

   create : myapp/views/error.pug
   create : myapp/bin

# Then install dependencies:
cd myapp

# On MacOS or Linux, run the app with this command:
DEBUG=myapp:* npm start
