Exploring Angular CLI

Table of Contents


Angular CLI (Command Line Interface) is a powerful tool that simplifies and accelerates the development process for building dynamic and responsive web applications using the Angular framework. It provides developers with a seamless way to generate components, services, modules, and other application features, along with various development, testing, and deployment utilities. In this blog, we’ll take a deep dive into the Angular CLI, exploring its key features, commands, and benefits that make it an indispensable tool for Angular developers.

What is Angular CLI?

It is a command-line tool that simplifies the process of creating, building, testing, and deploying Angular applications. It abstracts complex configurations and setups, allowing developers to focus on writing application code rather than dealing with tedious setup tasks.

Installing Angular CLI

To get started, you need to install Node.js and npm (Node Package Manager) on your system. Once that’s done, you can install Angular CLI globally using the following command:

npm install -g @angular/cli

Key Features and Benefits

a. Project Generation: Angular CLI enables you to create a new Angular project with a single command, including the basic file structure, configurations, and dependencies.

b. Code Generation: Quickly generate components, services, modules, directives, and more using CLI commands, saving time and ensuring consistent code patterns.

c. Development Server: Run a local development server with live reloading to see your changes in real time as you work on your application.

d. Testing Utilities: Angular CLI integrates testing tools like Jasmine and Karma, making it easy to run unit tests, and end-to-end tests, and generate code coverage reports.

e. Build and Deployment: Create optimized production builds and deploy them to various hosting platforms effortlessly.

CLI Commands

a. Generating Components

Use the ng generate component command to create a new component. For example:

ng generate component my-component

b. Creating Services

Generate services using the ng generate service command:

ng generate service my-service

c. Generating Modules

Create modules with the ng generate module command:

ng generate module my-module

d. Building and Deploying

Build your application for production using:

ng build --prod

Deploy the build to a hosting platform of your choice.

Customizing Angular CLI

You can customize various aspects of your project using configuration files like angular.json and tsconfig.json. These files allow you to tailor your build settings, include/exclude files, and more.


Angular CLI is an indispensable tool for Angular developers, offering a range of features and commands that streamline the development process. Its ability to generate code, manage dependencies, and facilitate testing and deployment makes it a must-have in the Angular ecosystem. By mastering this, developers can boost their productivity and focus on building outstanding web applications.
