Angular CLI is one of the best tool available for angular to setup the initial files or scaffolding structure of the application.

Setup

Once you have setup the basic software like node.js and npm. You can download CLI using the following command

npm install -g @angular/cli

Once installed we can check the version of angular CLI using the following command

ng version

One common arguments every CLI has is help command. Here it is for you

ng help

From your target empty folder, you need to run the following command to generate the basic files/

ng new my-first-project

Make sure to replace ‘my-first-project’ with name you prefer. This is will your application name.

Angular CLI have lots of others option to help in setting the basic to advance files.

Creating new angular project

ng new timer-project

timer-project is name of project we chose.

The CLI asks us choose our required options based on our needs. Like routing and stylesheet type.

After installing package, we are good to go with debugging of the newly generated application. We can discuss about the project structure in our upcoming post.

Serving the project

Angular CLI provides a complete tool-chain for developing front-end apps on your local machine. As such, you don’t need to install a local server to serve your project — you can simply, use the ng serve command from your terminal to serve your project locally.

ng serve

The application will start serving in the root http://localhost:4200

Generating angular schematic

Generates and/or modifies files based on a schematic.

ng generate <schematic> [options]
ng g <schematic> [options]

schematic can be replaced with following sets

  • appShell
  • application
  • class
  • component
  • directive
  • enum
  • guard
  • interceptor
  • interface
  • library
  • module
  • pipe
  • service
  • serviceWorker
  • webWorker

These commands is fair to start using angular CLI in beginner mode.

Happy Coding!
