Routing in Angular App

Routing in Angular app is an important feature that allows navigation between different parts of the application without reloading the entire page. It helps in creating a more seamless user experience and organizing the application into multiple views or pages.

Setting up Routing

To set up routing in an Angular app, you need to import the RouterModule and Routes modules from @angular/router package in your app module file. Then, define routes for different views or components in an array format with path and component properties.

    
    const routes: Routes = [
      { path: 'home', component: HomeComponent },
      { path: 'about', component: AboutComponent },
      { path: 'contact', component: ContactComponent }
    ];
    
    

After defining routes, you need to import RouterModule.forRoot(routes) in the imports array of your app module file to enable routing in your Angular app.

Routing in Components

To navigate between different views or components in an Angular app, you can use the routerLink directive in your HTML templates. This directive takes the path defined in the routes array and navigates to the corresponding component when clicked.

    
    <nav>
      <a routerLink="/home">Home</a>
      <a routerLink="/about">About</a>
      <a routerLink="/contact">Contact</a>
    </nav>
    
    

When a user clicks on a link with routerLink directive, Angular router will navigate to the specified path and load the corresponding component into the directive defined in the app component HTML template.

Handling Route Parameters

In some cases, you may need to pass parameters or data to a component when navigating to a route. Angular router provides the ActivatedRoute service to access route parameters and data in the target component.

    
    constructor(private route: ActivatedRoute) {
        this.route.params.subscribe(params => {
            this.id = params['id'];
        });
    }
    
    

By subscribing to the params property of ActivatedRoute service, you can access the route parameters and use them in your component logic.

Routing in Angular app is a powerful feature that enables seamless navigation between different views or components. By defining routes, using routerLink directive, and handling route parameters, you can create a more interactive and dynamic user experience in your Angular app.
