What is preventing the route with parameters from functioning properly in Angular2?

I'm currently working on implementing a basic route with a parameter in Angular2. My setup involves Angular 2.0.0-rc.2 and angular router 3.0.0-alpha.7. I've mostly relied on the updated routing documentation available at https://angular.io/docs/ts/latest/guide/router.html

index.html

<!doctype html>
  <html>
    <head>
      <base href=".">
      ...

main.ts

import { bootstrap } from '@angular/platform-browser-dynamic';
import { AppComponent } from './app';
import { HTTP_PROVIDERS } from '@angular/http';
import { APP_ROUTER_PROVIDERS } from './app/app.routes';

bootstrap(AppComponent, [
    HTTP_PROVIDERS,
    APP_ROUTER_PROVIDERS
])
    .catch(err => console.error(err))
;

app.routes.ts

export const routes: RouterConfig = [
    { path: 'featured',       component: FeaturedPageComponent },
    { path: 'containers/:id', component: ContainerEditComponent }
];

export const APP_ROUTER_PROVIDERS = [
    provideRouter(routes)
];

container-edit.component.ts

@Component({
    moduleId: module.id,
    selector: 'container-edit',
    templateUrl: 'container-edit.component.html',
    styleUrls: ['container-edit.component.css']
})
export class ContainerEditComponent implements OnInit, OnDestroy {
    private sub: any;

    constructor(
        private route: ActivatedRoute,
        private router: Router
    ) {
    }

    ngOnInit() {
        this.sub = this.route.params.subscribe(params => {
            let id = +params['id']; // + converts string to number
            console.log(id);
        });
    }

    ngOnDestroy() {
        this.sub.unsubscribe();
    }
}

When trying to access

http://localhost:4200/containers/1337
, I come across the following error message.

EXCEPTION: Error: Uncaught (in promise): Error: Cannot match any routes: '1337'

Answer №1

Revised Response:

To ensure proper routing in your Angular2 application, it is recommended to set your base to <base href="/" /> within your index.html file. While the Angular2 documentation often suggests using <base href="." />, it is important to consider your specific project requirements. If you need users to navigate directly to a specific path, then using / as the base href is necessary.

Original Answer:

If you are experiencing issues with your routes, double check the paths you have set. It is possible that the 'app' subfolder was not intended to be included based on the samples provided.

import { AppComponent } from './app/'; <--- Verify this path
import { HTTP_PROVIDERS } from '@angular/http';
import { APP_ROUTER_PROVIDERS } from './app/app.routes'; <--- Check this path as well
