Angular2 Exception: Can't bind to 'routerLink' since it isn't a known native property

Obviously the beta for Angular2 is newer than new, so there's not much information out there, but I am trying to do what I think is some fairly basic routing.

Hacking about with the quick-start code and other snippets from the https://angular.io website has resulted in the following file structure:


With the files being populated as follows:



<base href="/">
<title>Angular 2 QuickStart</title>
<link href="../css/bootstrap.css" rel="stylesheet">

<!-- 1. Load libraries -->
<script src="node_modules/angular2/bundles/angular2-polyfills.js"></script>
<script src="node_modules/systemjs/dist/system.src.js"></script>
<script src="node_modules/rxjs/bundles/Rx.js"></script>
<script src="node_modules/angular2/bundles/angular2.dev.js"></script>
<script src="node_modules/angular2/bundles/router.dev.js"></script>

<!-- 2. Configure SystemJS -->
packages: {
app: {
format: 'register',
defaultExtension: 'js'
.then(null, console.error.bind(console));


<!-- 3. Display the application -->



import {bootstrap} from 'angular2/platform/browser'
import {ROUTER_PROVIDERS} from 'angular2/router';

import {AppComponent} from './app.component'

bootstrap(AppComponent, [


import {Component} from 'angular2/core';
import {RouteConfig, ROUTER_DIRECTIVES, ROUTER_PROVIDERS, LocationStrategy, HashLocationStrategy} from 'angular2/router';

import {RoutingTestComponent} from './routing-test.component';

selector: 'my-app',
template: `
<h1>Component Router</h1>
<a [routerLink]="['RoutingTest']">Routing Test</a>

{path:'/routing-test', name: 'RoutingTest', component: RoutingTestComponent, useAsDefault: true},

export class AppComponent { }


import {Component} from 'angular2/core';
import {Router} from 'angular2/router';

template: `
<h2>Routing Test</h2>
<p>Interesting stuff goes here!</p>
export class RoutingTestComponent { }

Attempting to run this code produces the error:

EXCEPTION: Template parse errors:
Can't bind to 'routerLink' since it isn't a known native property ("
<h1>Component Router</h1>
<a [ERROR ->][routerLink]="['RoutingTest']">Routing Test</a>
"): [email protected]:11

I found a vaguely related issue here; router-link directives broken after upgrading to angular2.0.0-beta.0. However, the "working example" in one of the answers is based on pre-beta code - which may well still work, but I would like to know why the code I have created is not working.

Any pointers would be gratefully received!

Your code is missing

    directives: [ROUTER_DIRECTIVES],

You can't use directives like routerLink or router-outlet without making them known to your component.

While directive names were changed to be case-sensitive in Angular2, elements still use - in the name like <router-outlet> to be compatible with the web-components spec which require a - in the name of custom elements.

register globally

To make ROUTER_DIRECTIVES globally available, add this provider to bootstrap(...):

provide(PLATFORM_DIRECTIVES, {useValue: [ROUTER_DIRECTIVES], multi: true})

then it's no longer necessary to add ROUTER_DIRECTIVES to each component.
