A Beginner's Guide to Setting Up Angular Development Environment

If you’re an Angular developer, setting up your development environment can be challenging for the first time. It is essential to have everything configured correctly before you start developing your Angular application. This guide will walk you through setting up your Angular development environment correctly.

Installing Node.js

Angular is built on top of Node.js, a JavaScript runtime. Therefore, you need to install Node.js to configure your Angular development environment. To download and install Node.js on your machine, visit the official website of Node.js, and download the package that suits your operating system. Once you have downloaded the package, install it on your system by double-clicking on the installer file.

Installing the Angular CLI

After installing Node.js on your system, you need to install Angular CLI. The Angular Command Line Interface (CLI) is a powerful tool that helps you create, manage, and deploy Angular applications. To install Angular CLI, open a command prompt or terminal on your machine and run the following command:

npm install -g @angular/cli

This command will install the latest version of Angular CLI globally on your system. Once the installation is complete, you can verify the installation by running the following command:

ng version

This command will display the version of Angular CLI along with other dependencies that are installed on your system.

Setting Up a Code Editor

To develop your Angular application, you need to have a code editor. There are many code editors available, such as Visual Studio Code, Sublime Text, Atom, etc. In this guide, we will use Visual Studio Code since it is a lightweight and powerful code editor that is widely used in the Angular community. You can download Visual Studio Code from their official website and install it on your system.

Creating Your First Angular Application

Once you have set up your development environment, it is time to create your first Angular application. To create a new Angular application, open a command prompt or terminal on your system and navigate to the directory where you want to create your application.

cd your_directory_path

Once you are in the correct directory, run the following command to create a new Angular application:

ng new my-app

This command will create a new Angular application with the name “my-app” and install all the necessary dependencies that are required for your application to run. Once the installation is complete, navigate to the newly created directory using the following command:

cd my-app

Now that you are inside the newly created directory, you can run your Angular application using the following command:

ng serve

This command will start the development server, and your Angular application will be available at http://localhost:4200

Conclusion

Setting up your Angular development environment can be challenging for the first time. However, with the right tools and a little bit of practice, you can quickly set up your development environment and start developing your Angular application. In this guide, we covered the essential steps required to set up your Angular development environment, including installing Node.js and Angular CLI, setting up a code editor, and creating your first Angular application. Now you are ready to dive into the exciting world of Angular development!
