What is the method for including Location in a function within the NgModule declaration?

Below is the code snippet I am working with:

@NgModule({
    imports: [
     ..

    TranslateModule.forRoot({
        loader: {
            provide: TranslateLoader,
            useFactory: (createTranslateLoader),
            deps: [HttpClient]
        }
        }),
 ...

    ],

The implementation of createTranslateLoader function look like this:

export function createTranslateLoader(http: HttpClient) {
    let fullLocationPath = location.origin + location.pathname;
     // Trying to access Angular's location service here.
    return new TranslateHttpLoader(http, fullLocationPath  + 'assets/languages/', '.json');
}

I'm having trouble using Angular's location service in the createTranslateLoader function. Any suggestions or documentation on how to achieve this? Check out the Angular Location API for more information.

In order to utilize the location feature in Angular, you must provide a location yourself and specify the LocationStrategy according to the documentation:

import { Location, LocationStrategy, PathLocationStrategy } from '@angular/common';

@NgModule({
    imports: [
    ...
    TranslateModule.forRoot({
        loader: {
            provide: TranslateLoader,
            useFactory: createTranslateLoader,
            deps: [HttpClient]
        }
        }),
        ...

    ],

    providers: [Location, {provide: LocationStrategy, useClass: PathLocationStrategy}],

There are 3 options for location strategies that can be passed:

  • HashLocationStrategy
  • PathLocationStrategy
  • MockLocationStrategy
