What is Routing in Angular

Setting up Routing in Angular

Angular’s routing module allows you to create single-page applications (SPAs) by enabling navigation between different components and views.

Router Module:

• Angular applications typically have a dedicated routing module that imports the RouterModule and sets up routes.

// Example of an Angular routing module
@NgModule({
  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule]
})
export class AppRoutingModule { }

Route Configuration:

• Define routes in the routing module by specifying the path and associated component.

// Example of route configuration in Angular
const routes: Routes = [
  { path: 'home', component: HomeComponent },
  { path: 'about', component: AboutComponent },
  { path: 'contact', component: ContactComponent }
];

Route Parameters and Navigation

Angular supports passing parameters in the URL and navigating between routes programmatically.

Route Parameters:

• Define parameters in the route path and access them in the component using the ActivatedRoute service.

// Example of route with parameter in Angular
{ path: 'user/:id', component: UserComponent }

// Example of accessing route parameters in Angular component
constructor(private route: ActivatedRoute) {
  this.userId = this.route.snapshot.params['id'];
}

Navigating Between Routes:

• Use the Router service to navigate between routes programmatically.

// Example of navigating between routes in Angular
this.router.navigate(['/user', userId]);

Nested Routes and Route Guards

Angular supports nested routes, allowing you to organize components hierarchically. Additionally, route guards provide a way to control access to routes.

Nested Routes:

• Configure nested routes in the routing module by defining child routes for a parent route.

// Example of nested routes in Angular
{ path: 'dashboard', component: DashboardComponent, children: [
  { path: 'overview', component: OverviewComponent },
  { path: 'stats', component: StatsComponent }
]}

Route Guards:

• Implement route guards to control access to routes. Common guards include CanActivate, CanDeactivate, and CanLoad.

// Example of route guard in Angular
canActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): boolean {
  // Logic to determine whether the route can be activated
  return true; // or false
}
