How to Create a New Angular Project in Visual Studio Code with Code Examples

Angular is an open-source JavaScript framework maintained by Google that helps to build web applications, from small to large-scale projects. Angular provides a robust set of tools and features to develop web applications. Many developers prefer to use Microsoft Visual Studio Code as their development environment to build Angular applications. Visual Studio Code is a free, lightweight, and powerful code editor developed by Microsoft and available for Windows, Mac, and Linux.

In this article, you will learn how to create a new Angular project in Visual Studio Code with code examples. We will use Angular CLI, a command-line interface for Angular, to create a new project. Angular CLI provides a set of commands to generate components, services, modules, pipes, directives, and many other Angular artifacts.

Step 1: Install Node.js and Angular CLI

Before creating a new Angular project, you need to install Node.js and Angular CLI on your system. Node.js is a JavaScript runtime built on Chrome's V8 JavaScript engine. Angular CLI is a command line interface for Angular. Follow the steps below to install Node.js and Angular CLI:

1. Download and install Node.js from https://nodejs.org. You can choose the version based on your operating system.
2. Open a new terminal window and run the following command to install Angular CLI:

npm install -g @angular/cli

Step 2: Create a New Angular Project

Once you have installed Node.js and Angular CLI, you can create a new Angular project by running one command in the terminal. Follow the steps below to create a new Angular project:

1. Open Visual Studio Code.
2. Open a new terminal window in Visual Studio Code by pressing the Ctrl+Shift+` or Cmd+Shift+` keyboard shortcut.
3. Run the following command to create a new Angular project:

ng new my-app

This command will create a new Angular project named my-app in the current directory. The Angular CLI will generate a new project with the following files and folders:

- src/                                     # Source files
  - app/                                  
    - app.component.{ts,css,html,spec.ts}  # Main component
    - app.module.ts                       # Main module
    - ...
  - assets/                                # Static files (images, fonts, etc)
  - environments/                          # Environment configuration files
  - index.{html,css}                       # HTML and CSS files
- ...

Step 3: Serve the Angular Application

After creating a new Angular project, you can run the project in the development mode by serving the Angular application. Follow the steps below to serve the Angular application:

1. Open a new terminal window in Visual Studio Code.
2. Change the directory to the project directory by running the following command:

cd my-app

3. Run the following command to serve the Angular application:

ng serve

This command will start a development server that watches the changes in the source files and updates the browser automatically. The Angular application will be available at http://localhost:4200. You can open this URL in your browser to see the default Angular application.

Step 4: Modify the Angular Application

Now that you have created a new Angular project and served the application, you can modify the application to fit your needs. Follow the steps below to modify the Angular application:

1. Open the src/app/app.component.html file in Visual Studio Code.
2. Replace the content of this file with the following HTML code:

<h1>Welcome to my Angular application!</h1>

3. Save the file and switch to your browser. You should see the updated content of the Angular application.

Congratulations! You have successfully created a new Angular project in Visual Studio Code and modified the application. You can use Angular CLI to generate more Angular artifacts by running the following commands:

ng generate component my-component   # Generate a new component
ng generate module my-module         # Generate a new module
ng generate service my-service       # Generate a new service
ng generate pipe my-pipe             # Generate a new pipe
ng generate directive my-directive   # Generate a new directive

Conclusion

Angular is a popular JavaScript framework used by many developers to create web applications. Microsoft Visual Studio Code is a popular code editor used by many developers to write Angular applications. In this article, we learned how to create a new Angular project in Visual Studio Code using Angular CLI and how to serve the application. We also learned how to modify the Angular application and generate more Angular artifacts using Angular CLI.
