Build the project

Install dependencies :

$ npm install

or

$ yarn

Build the cli bundle :

$ npm run build

Note :

• The bundle file is created into assets/app directory
• if NODE_ENV is set to production, the bundle is uglyfied/minified without sourcemaps.

Start the server :

$ npm start

Note : if NODE_ENV is set to development, the server is started with nodemon and webpack middleware is used to hot reload the cli.
