Getting Started with Angular

Setting up the Development Environment

Before you start building Angular applications, it’s essential to set up your development environment. Angular requires Node.js and npm (Node Package Manager) for managing dependencies.

Node.js Installation:

• Visit the official Node.js website to download and install Node.js on your machine.

Angular CLI Installation:

• Once Node.js is installed, open a terminal and install the Angular CLI globally using the following command:

npm install -g @angular/cli

Verify Installation:

• Confirm that both Node.js and the Angular CLI are installed by running:

node -v
npm -v
ng --version

Creating Your First Angular Application

Now that your development environment is set up, let’s create a simple Angular application.

Generate a New Project:

• Use the Angular CLI to generate a new project:

ng new my-first-app

Navigate to the Project:

• Change into the newly created project directory:

cd my-first-app

Serve the Application:

• Start a development server to see your Angular application in action:

ng serve

View in Browser:

• Open your browser and navigate to http://localhost:4200/ to view your running Angular application.

Understanding the Project Structure

Angular projects follow a specific structure that helps organize code and resources effectively.

• src Folder:
  • The main source code of your application resides in the src folder.
• app Folder:
  • The app folder contains your Angular components, services, and other application-specific code.
• angular.json:
  • Configuration file for Angular CLI settings.
• index.html:
  • The main HTML file that serves as the entry point for your Angular application.

Conclusion

In this post, we’ve covered the initial steps to set up your development environment, create a new Angular application, and understand the project structure. Moving forward, we’ll explore Angular components and how to build the user interface of your application.
