Introduction to Angular CLI Commands

Angular is a framework that is used to create a web application. Angular uses typescript to write our business logic and methods but the browser does not understand typescript. The browser understands JavaScript. So that’s why angular CLI comes into picture that does all these things in some simple commands for us. Angular CLI basically uses a webpack to do all this process.

Angular CLI Commands

Here we are going to learn Angular CLI commands with detail explanation.

Install Angular CLI, for this first we need to install the CLI from the below command.

npm install - g @angular/cli

Step 2: Create a new angular project by using the below command.

ng new myNewApp

1. add

If we want to add an extra library then we should go with this command. ng add command is basically used to add an extra or external library to our project. It adds the npm packages to our workspace and we can use this library into our project for development. Suppose we add any external library like angular material we want to use then we need to add this into our workspace.

Command Syntax:

ng add <collection> [options]

Explanation:

<collection>: This specifies the package we want to add in our project.

2. config

It saves the configuration value for our angular project. basically it set and retrieves the angular configuration value into the angular.json file for our project.

Command Syntax:

ng config <jsonPath> <value> [options]

Explanation:

  • <jsonPath>: It set or query the key value from the json path format. If we do not set the new value for this key it will return the current value for this key.
  • <value>: It provides the value for the given configuration key. If we provide them new value it will show new value for the given key.

  • [options]
    • –prod=true|false: Its default value is false. when set to true it will bring all the build configuration to the projection target. A production build also runs limited dead code elimination.
    • –help= true|false|json|JSON: It will show help message for this command on the console.
