javascript - Angular 2 - how to use the new angular 2.0.0-rc.1 router

Question

I've started to write a new angular 2 project and I found that I installed 2 angular router:

1. "@angular/router": "2.0.0-rc.1",
2. "@angular/router-deprecated": "2.0.0-rc.1",

I didn't find in the angular site how to use the new router. For example, what component do I need to import.

So my questions are:

1. Should I use the router-deprecated?
2. Is there any good doc for how to use the new router?

question from:https://stackoverflow.com/questions/37089662/angular-2-how-to-use-the-new-angular-2-0-0-rc-1-router

Answer 1

Here is how to use the Angular 2 Router (RC1), compared to the beta (deprecated) one:

• Routes replaces RouteConfig.

• Inside your config there is a new syntax:

  {path: '/path', component: MyPathComponent}

  instead of:

  {path:'/path', name: 'MyPath', component: MyPathComponent}

• Using routerLink is now like that:

  <a [routerLink]="['/path/2']">Click to navigate</a>

  Instead of:

<a [routerLink]="['MyPath', 'Detail', {id:2}]">Shark Crisis</a>

• Also there is no RouteParams anymore, instead you get the params using the router lifecycle hooks: CanActivate, OnActivate, and CanDeactivate.

If you used params inside ngOnInit, you can do that like this now:

routerOnActivate(curr: RouteSegment): void {
           curr.getParam('id');
       }

You will end up having something like this:

import {ROUTER_DIRECTIVES, Router, Routes} from "@angular/router";

@Injectable()
@Component({
    selector: "my-app",
    templateUrl: `<a [routerLink]="['/component1']">Click to go to component 1</a>`,
    directives: [ROUTER_DIRECTIVES]
})
@Routes([
    {path: "/component1", component: Component1},
    {path: "/component2", component: Component2}
])
export class AppComponent {
    constructor(private _router: Router) {
        //If you want to use Router in your component (for navigation etc), you can inject it like this
    }
}

Update (9/6/16): It seems that Angular 2 RC1 Router is being deprecated like the old one. The new recommendation is to use version 3.0.0-alpha.3 of @angular/router.
