Building Your First Angular Application with CLI

When it comes to building Angular applications, CLI (Command Line Interface) is the go-to tool for developers. With just a few commands, you can easily create and manage your Angular projects, components, and services. In this article, we’ll walk you through the steps of building your first Angular application using the CLI.

Step 1: Install Angular CLI

Before you can start building your Angular project, you need to have the Angular CLI installed on your system. You can install it using the following command:

npm install -g @angular/cli

Step 2: Create a New Angular Project

Once you have installed the Angular CLI, you can create a new Angular project using the following command:

ng new my-app

This command will create a new project with the name ‘my-app’. You can replace ‘my-app’ with any name of your choice.

Step 3: Serve the Application

After you have created your Angular project, you can serve it using the following command:

cd my-app
ng serve

This command will compile your application and serve it on a localhost server at port 4200.

Step 4: Add Components and Services

Now that you have your Angular application up and running, you can start adding components and services to it. You can generate a new component using the following command:

ng generate component my-component

This command will create a new component with the name ‘my-component’. You can also generate new services, modules, and pipes in the same way.


Using the Angular CLI makes it easy to create and manage your Angular projects. With just a few simple commands, you can have your application up and running in no time.

Deploying Your Angular App with the CLI

If you have just finished building an Angular app using the Angular CLI, it’s now time to deploy it. Deploying the app makes it accessible to your end-users and allows them to interact with the app. Fortunately, deploying your Angular app with the CLI is a straightforward process.

The first thing you need to do is open your Angular app’s terminal or command prompt and navigate to the root directory of the project. Once that’s done, you can run the following command:

ng build --prod

This command will build your Angular app in production mode. It will also create a dist/ folder which contains all the files required to deploy your app.

After the build process is complete, you can deploy the app to your hosting platform of choice. This hosting platform could be your own server or a cloud-based server like AWS, Google Cloud, or Microsoft Azure. The specific deployment process depends on the hosting platform you’re using. You may need to set up a server, configure it, and upload the files manually, or you can use automated deployment tools like CircleCI, TravisCI, or Jenkins to deploy your app.

Once your app is deployed, you can access it by visiting the URL associated with your hosting platform.

And that’s it! Deploying your Angular app with the CLI is that simple. So, don’t hesitate to deploy your app and share it with the world.

Analyzing Performance in Your Angular App with CLI Tools

Analyzing performance in your Angular app is crucial to ensure that your app runs smoothly and efficiently. One way to achieve this is by using CLI (Command Line Interface) tools.

CLI tools provide a set of performance analysis and debugging tools that help you identify and resolve performance issues in your Angular app. The Angular CLI in particular provides a range of performance-focused commands that allow you to analyze and optimize different aspects of your app, including the build, bundle sizes, and network performance.

Some of the CLI commands that can help you analyze performance in your Angular app include:

– “ng build –prod”: This command creates a production-ready build of your app that is optimized for performance. This includes features such as production mode, ahead-of-time compilation, tree shaking, and more.

– “ng analyze”: This command analyzes your app and provides a detailed report on issues related to size, performance, and other metrics. It helps you identify and fix issues such as unused code, redundant dependencies, and more.

– “ng lint”: This command checks your app’s code for potential issues and optimizations. It helps you identify areas of your code that can be improved for better performance.

By using these CLI commands, you can significantly improve the performance of your Angular app and deliver a better user experience to your users. So, next time you develop Angular apps, don’t forget to leverage the power of CLI tools to analyze and optimize your app’s performance.

Advanced Techniques for Customizing the Angular CLI

The Angular CLI is a powerful tool for generating, managing, and building Angular applications. While the CLI comes with a default set of configuration options and features, it can also be customized to meet the specific needs of your project.

Here are some advanced techniques for customizing the Angular CLI:

  • Customizing webpack configuration: The Angular CLI abstracts away the underlying webpack configuration, but you can access and modify it using the “angular.json” file.
  • Configuring environment-specific variables: The Angular CLI allows you to define different environments, such as development, staging, and production. You can also define environment-specific variables to be used within your application.
  • Adding custom schematics: Schematics are a powerful way to generate code and modify files within your Angular application. You can create custom schematics that integrate with the Angular CLI.
  • Using third-party plugins: There are several third-party plugins that extend the functionality of the Angular CLI, such as the “ngx-build-plus” plugin that allows you to configure advanced webpack features.

By mastering these advanced techniques, you can take your Angular development to the next level and create applications that are tailored to your specific needs.
