"Troubleshooting the routerLink binding issue in Angular 2 beta14 with Types

In my endeavor to construct a wizard using Angular2's router, I stumbled upon the suggestion of having a main bootstrap file by Angular2, which then bootstraps all the app components. However, as I am unable to create a Single Page Application (SPA), I desire for each page to independently bootstrap its own components.

Upon running the application, an error regarding routerLink presents itself:

"EXCEPTION: Template parse errors: Can't bind to 'routerLink' since it isn't a known native property ("For="#wizard of Wizards" [selected]="SelectedWizard == wizard" [value]="wizard.name" [ERROR ->][routerLink]="'' + wizard.path + ''">{{wizard.name}} "

Here is the code snippet from my page component:

/// <reference path="angular2/typings/browser.d.ts" />
/// <reference path="angular2/core.d.ts" />
/// <reference path="angular2/router.d.ts" />

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

import {Wizard1} from './wizard1';
import {Wizard2} from './wizard2';
import {Step1} from './step1';
import {Step2} from './step2';
import {Step3} from './step3';
import {Step4} from './step4';
import {Step5} from './step5';

//Rest of the code here ...

Wizard1

/// <reference path="angular2/core.d.ts" />
/// <reference path="angular2/router.d.ts" />

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

//Rest of the code here ...

Wizard2

/// <reference path="angular2/core.d.ts" />
/// <reference path="angular2/router.d.ts" />

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

//Rest of the code here ...

All steps are similar to this, in their own .ts files

/// <reference path="angular2/core.d.ts" />
/// <reference path="angular2/router.d.ts" />

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

//Rest of the code here ...

Encountering any issues or difficulties with this setup?

Environment

  1. Visual Studio 2015 update 1
  2. ASP.NET 5 and MVC 6
  3. DNX 4.5.1 and 5.0
  4. Angular2 Typescript

Answer №1

You can enhance your component providers by including the ROUTER_DIRECTIVES:

@Component({directives: [ROUTER_DIRECTIVES]})

Answer №2

It appears that you have forgotten to import ROUTER_DIRECTIVES in the Page components & directives option within the ComponentMetaData. This is why Angular does not recognize the routerLink & routerOutlet directives on the page. Make sure to add the following line:

import {ROUTER_PROVIDERS, ROUTER_DIRECTIVES} from 'angular2/router';

Afterwards, inject ROUTER_DIRECTIVES into the directives option of that component:

@Component({
    selector: 'page',
    //....
    //other options
    //....
    directives: [ROUTER_DIRECTIVES]
})

Also, it seems like you may have bootstrapped your application multiple times. Ideally, there should only be one main component, with other components being children of it.
