Angular is a popular open-source web application framework developed by Google. The Angular API provides a rich set of functionalities for building dynamic and efficient web applications. Below is a brief overview of the Angular API.

Overview

  • Version: Angular API supports various versions, with the latest being Angular 14.
  • Key Features: Two-way data binding, dependency injection, modular architecture, and command-line interface (CLI).

Installation

To get started with Angular, you can use the following command:

ng new my-angular-app

This command creates a new Angular project named my-angular-app.

Components

Angular components are the building blocks of Angular applications. They are used to create reusable UI elements.

  • Creating a Component: Use the CLI to generate a new component:
ng generate component my-component
  • Using a Component: Import the component in your module and add it to the template.

Directives

Directives are used to perform actions on elements. Some commonly used directives include:

  • ngFor: Iterate over a list of items.
  • ngIf: Conditionally display elements.
  • ngClass: Apply CSS classes dynamically.

Services

Services are used to encapsulate and share logic across components. They can be injected into components using the @Injectable decorator.

@Injectable({
  providedIn: 'root'
})
export class MyService {
  // Service logic here
}

Routing

Angular routing allows you to navigate between different views in your application.

  • Setting Up Routing: Define routes in your app-routing.module.ts file.
const routes: Routes = [
  { path: '', component: HomeComponent },
  { path: 'about', component: AboutComponent }
];

@NgModule({
  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule]
})
export class AppRoutingModule { }
  • Navigating: Use the <router-link> directive to navigate to different routes.
<a routerLink="/about">About</a>
