  • Directives: Discover Angular directives, which are used to manipulate the DOM and add custom behaviors to elements.
  • Services and Dependency Injection: Learn about Angular services, which are used to encapsulate reusable logic, and the dependency injection mechanism that allows you to easily provide services to components.
  • Routing: Explore Angular’s built-in routing module, which enables you to create sophisticated navigation structures for your SPA.
  • Forms: Get comfortable with Angular’s form handling capabilities, including both template-driven and reactive forms.
  • HTTP Client: Understand how to make HTTP requests and interact with APIs using Angular’s built-in HttpClient module.

Building Your First Angular App

  1. Set up your development environment by installing Node.js and npm (Node Package Manager).
  2. Install the Angular CLI using npm install -g @angular/cli.
  3. Create a new Angular project by running ng new my-first-angular-app (replace “my-first-angular-app” with your desired project name).
  4. Navigate to the project directory using cd my-first-angular-app and start the development server using ng serve.
  5. Open your favorite code editor and explore the project structure. Modify the src/app/app.component.ts and src/app/app.component.html files to create your first component.
