Unexpected behavior with HashLocationStrategy

I am currently tackling a project in Angular2 using TypeScript, and I seem to be having trouble with the HashLocationStrategy. Despite following the instructions on how to override the LocationStrategy as laid out here, I can't seem to get it to work properly.

import {bootstrap}         from 'angular2/platform/browser';
import {ROUTER_PROVIDERS}  from 'angular2/router';
import {AppComponent}      from './app.component';
// Utilize these symbols for overriding the `LocationStrategy`
import {provide}           from 'angular2/core';
import {LocationStrategy,
        HashLocationStrategy} from 'angular2/router';
bootstrap(AppComponent, [
  ROUTER_PROVIDERS,
  provide(LocationStrategy,
         {useClass: HashLocationStrategy})
]);

I've put together a plunker showcasing the issue here: https://plnkr.co/edit/YE5w4iky53SHRi211lqX?p=preview

Is anyone else facing the same problem? Do you think I've misinterpreted something or overlooked a crucial detail?

Edit: The desired outcome is for the routing to incorporate hashes in the URL. For example, instead of .../fubar, it should display .../#/fubar in the URL as demonstrated in the example.

To view the resulting URLs, it's recommended to open the plunker in a separate window (click on the blue full-screen button).

Answer №1

This particular example does not adhere to the recommended best practices of separating bootstrap and app code into different files, which can be a bit confusing.

If you move the HashLocation code into your app.component file, it should work fine:

app.ts

import [..]

@Component({
    [..]
    providers:[
        ROUTER_PROVIDERS,
        provide(LocationStrategy, {useClass: HashLocationStrategy})]
})
@RouteConfig([..])
    export class App{
        [..]
    }

boot.ts

import [..]
[..]
bootstrap(App);

Please check out my modified version of your plunker for reference:

It's possible that the issue arises from overwriting the "providers" attribute in the AppComponent, as seen in some examples.

Exploring the beta version of angular 2 has led to a fascinating question and answer session. To see Angular 2.3 in action, check out this live example showcased in the official documentation here

import { NgModule }             from '@angular/core';
import { BrowserModule }        from '@angular/platform-browser';
import { FormsModule }          from '@angular/forms';
import { Routes, RouterModule } from '@angular/router';

import { AppComponent }          from './app.component';
import { PageNotFoundComponent } from './not-found.component';

const routes: Routes = [

];

@NgModule({
  imports: [
    BrowserModule,
    FormsModule,
    RouterModule.forRoot(routes, { useHash: true })  // .../#/crisis-center/
  ],
  declarations: [
    AppComponent,
    PageNotFoundComponent
  ],
  providers: [

  ],
  bootstrap: [ AppComponent ]
})
export class AppModule { }
