Introduction to Angular CLI

Angular CLI is a command-line interface tool designed to make the development of Angular applications faster and more efficient. With Angular CLI, you can easily generate components, services, modules, and more, which helps maintain a consistent project structure and speeds up repetitive tasks.

For those looking to gain hands-on experience with Angular CLI commands and Angular development, AngularJS Online Training provides an excellent opportunity to learn with expert guidance.

Installing Angular CLI

To get started with Angular CLI, you’ll need to install it on your system. Follow these steps:

Make sure you have Node.js and npm installed on your system.
Open your terminal and run the following command:

npm install -g @angular/cli

After installation, you can verify the Angular CLI version by running:

ng version

Below are some of the most commonly used Angular CLI commands every developer should know:

1. Creating a New Angular Project

ng new project-name

Use this command to create a new Angular project. Replace “project-name” with your desired project title.

2. Running the Application

ng serve

This command builds and serves your Angular app, making it accessible at http://localhost:4200/ by default.

3. Generating Components

ng generate component component-name

Generates a new Angular component with all necessary files. Replace “component-name” with the name you want.

4. Generating Services

ng generate service service-name

Use this command to create a service, which is useful for handling data and business logic in Angular.

5. Building the Application

ng build

Builds your Angular app for deployment, optimizing it for production. You can add the --prod flag for additional optimizations.

6. Adding Modules

ng generate module module-name

Use this to create a module, which is helpful for organizing and lazy-loading parts of your Angular application.

7. Updating Angular and Dependencies

ng update

This command updates Angular and its dependencies to the latest version.

Angular CLI Command Syntax

Angular CLI commands follow a simple syntax structure that makes them easy to remember. Here is the syntax breakdown:

ng [command] [options]

For example:

ng generate component my-component --dry-run

In this command:

ng represents Angular CLI.
generate component specifies the action.
my-component is the name of the new component.
--dry-run runs the command without making changes to the file system.

Working with Angular Components

Components are the building blocks of an Angular application. The Angular CLI provides powerful commands for managing components, such as:

Generating a Component:
```
ng generate component my-component
```

Specifying the Path:

ng generate component path/to/my-component

Skipping Tests:

ng generate component my-component --skip-tests

Building and Serving Angular Applications

Building for Production

ng build --prod

Optimizes your app for production, reducing file sizes and improving performance.

Serving the Application

ng serve --open

Runs the app and opens it in your default browser. You can specify a different port with --port.

Advanced Angular CLI Commands

For more complex projects, the following Angular CLI commands can be very useful:

1. Generating Pipes

ng generate pipe pipe-name

2. Generating Directives

ng generate directive directive-name

3. Adding a Library

ng add @angular/material

4. Linting Your Code

ng lint

Analyzes your code for errors or inconsistencies based on Angular’s style guide.

5. Running Unit Tests

ng test

6. Running End-to-End Tests

ng e2e

7. Updating Angular CLI Configuration

ng config

Manages Angular CLI configuration options. For example, you can add global styles or set up a proxy.
