Installing Angular CLI

Angular CLI is the officially supported tool for creating and developing Angular applications. It is an open source project that is maintained by the Angular team and is the recommended way to develop Angular applications.

Angular CLI offers the following functionality:

• Create a new application

• Run the application in development mode

• Generate code using the best practices from the Angular team

• Run unit tests and end-to-end tests

• Create a production-ready build

One of the main benefits of using Angular CLI is that you don't need to configure any build tools. It's all abstracted away and available through one handy command: ng.

Throughout the book, we will be using the ng command for creating the app, generating the code, running the application in development mode, and creating builds.

Note

For more information about Angular CLI, refer to the project page on GitHub (https://github.com/angular/angular-cli)

To install Angular CLI on your machine, perform the following steps:

1. Open your terminal.

2. Run the following command:

   npm install –g @angular/cli@latest

3. Once the installation is finished without any errors, make sure that the ng command works as expected by running the following command:

   ng --version
