Getting Angular2 error 'No provider for Router! (RouterOutlet -> Router)'

Question

I use Angular2 alpha39 and Babel to transpile the ES6 JS file. I'm not using typescript.

I created a component which displays correctly. I added a router-outlet to the template. When I run the app, I get the error message:

No provider for Router! (RouterOutlet -> Router)

The call stack is:

Here is the snippet of code:

template:

.... // Removed for brevity
<div class="contenttext">
    <router-outlet></router-outlet>
</div>
.... // Removed for brevity

Component file:

import { Component, View, bootstrap,  OnInit } from 'angular2/angular2';
import { RouteConfig, RouterOutlet, RouterLink } from 'angular2/router';
import 'reflect-metadata';
import 'winjs';

@Component({
    selector: 'dashboard-app'
})
@View({
    templateUrl: '../js/dashboard.html',
    directives: [ ContentComponent, FamiliesComponent, RouterOutlet, RouterLink ]
})
@RouteConfig([ 
    { path: '/employees', component: EmployeesComponent, as: 'employees'} 
]) 
class DashboardAppComponent implements OnInit {
    constructor() {
    }

    onInit() {
        WinJS.UI.processAll().done(function() {
            var splitView = document.querySelector(".splitView").winControl;
            new WinJS.UI._WinKeyboard(splitView.paneElement);
        })
    }
}

bootstrap(DashboardAppComponent);

Answer 1

you have to use:

1. ROUTER_BINDINGS in your bootstrap.
2. in your index.html.
3. if possible use state i.e as "employees" in capitalize i.r as "Employees". (in alpha 42 i have solve one problem this way).

i hope this will surely help you.

--UPDATE--

after the relese of alpha41:

1. ROUTER_BINDINGS has been changed with ROUTER_PROVIDERS .
2. Router Aliases should be in the camel case manner.
3. for the Router-outler and router-link you just have to import ROUTER_DIRECTIVES in your directives property in the component annotation.
4. Router-link expects the value to be an array of route names. for more info. refer here .

for more info regarding Routing you may refer to this tutorial here .

---Update2---

1. Now ( as of alpha-49) router is exported as ng.router.

2. (According to alpha-47 all life cycle hooks renamed as.)

   onActivate, onReuse, onDeactivate, canReuse, canDeactivate

   To :--

   routerOnActivate,routerOnReuse,routerOnDeactivate,routerCanReuse,routerCanDeactivate

---Update3---

1. router-link is changed to routerLink

2. and routeconfig property changed to:

   {path: '/abc', component: ABC, as: 'abc'} to: {path: '/xyz' , component: XYZ, name: 'xyz'}

--Update 4 --

UPDATE TO ANGULAR2 RC

There are alot of changes has been made in routing in angular2 after RC some of them points i am going to mention here may help someone :-

1. angular2/router has been changed with @angular/router (also you can use old functionality of routing using import of @angular/router-deprecated but as of now we have to use @angular/router).

2. @RouteConfig has been changed with @Routes .

for example :-

@Routes([
  {path: '/crisis-center', component: CrisisListComponent},
  {path: '/heroes',        component: HeroListComponent}
])

Answer 2

2.0.0-alpha.36 (2015-08-31)

• routerInjectables was renamed to ROUTER_BINDINGS

2.0.0-alpha.41 (2015-10-13)

• ROUTER_BINDINGS was renamed to ROUTER_PROVIDERS

USE ROUTER_PROVIDERS

ROUTER_PROVIDERS is used to simplify bootstrapping the router.

It includes:

• RouterRegistry - the collection of registered routes
• LocationStrategy = PathLocationStrategy - match by path

ROUTER_PROVIDERS provides 'sane' defaults and should be used unless you need to need a different route LocationStrategy.

Change:

bootstrap(DashboardAppComponent);

To:

bootstrap(DashboardAppComponent, [
  ROUTER_PROVIDERS
]);

2.0.0-alpha.38 (2015-10-03)

Route aliases need to be CamelCase (technically PascalCase)

Note: this was mentioned already in Pardeep's answer under #3

If you want to include a link to a route in your template via router-link you have to make sure the alias (ie the name property) of the route is PascalCase.

If you use plan to use router-link modify the route to:

{ path: '/employees', component: EmployeesComponent, name: 'Employees'}

Then you can add the link in your template with:

<a [router-link]="['/Employees']">Employees Link</a>

RouterLink dynamically inserts a href that matches the route path.

Note: Reading the issue/pr it appears this change was made to prevent users from confusing the <route-link> binding with the route url

• angular/pr#4643

Tip:

If you want to simplify your view directives use ROUTER_DIRECTIVES

It includes:

• RouterLink
• RouterOutlet

Update:

In the near future, RouterOutlet/<router-outlet> will be renamed to RouterViewport/<router-viewport>

Update 2:

• The RouteConfig property as has been renamed to name
