Automating Tasks with Angular CLI

1. Introduction

Angular CLI (Command Line Interface) is a powerful tool that simplifies the development process of Angular applications. It allows developers to create, manage, and automate various tasks, enhancing productivity and efficiency.

2. Key Concepts

• **Commands**: Angular CLI provides various commands to create components, services, and other features.
• **Configuration**: The CLI uses a configuration file (`angular.json`) to manage project settings.
• **Schematics**: These are templates used by Angular CLI to generate different project files.
