Settings

Setting up `I18NRouterModule` to use `I18NRouterHttpLoader`

routes.json

{
  "en": {
    "ROOT.ABOUT": "about",
    "ROOT.ABOUT.US": "us",
    "ROOT.ABOUT.BANANA": "banana",
    "ROOT.ABOUT.APPLE": "apple",
    "ROOT.ABOUT.APPLE.PEAR": "pear",
    "CHANGE_LANGUAGE": "change-language"
  },
  "tr": {
    "ROOT.ABOUT": "hakkinda",
    "ROOT.ABOUT.US": "biz",
    "ROOT.ABOUT.BANANA": "muz",
    "ROOT.ABOUT.APPLE": "elma",
    "ROOT.ABOUT.APPLE.PEAR": "armut",
    "CHANGE_LANGUAGE": "dil-secimi"
  }
}

app.module.ts

...
import { HttpClient } from '@angular/common/http';
import { I18NRouterModule, I18NRouterLoader, I18NRouterHttpLoader, I18N_ROUTER_PROVIDERS, RAW_ROUTES } from '@ngx-i18n-router/core';
...

export function i18nRouterFactory(http: HttpClient, rawRoutes: Routes): I18NRouterLoader {
  return new I18NRouterHttpLoader(http, '/routes.json', {routes: rawRoutes}); // FILE PATH || API ENDPOINT
}

...

@NgModule({
  declarations: [
    AppComponent,
    ...
  ],
  ...
  imports: [
    RouterModule.forRoot(routes),
    I18NRouterModule.forRoot(routes, [
      {
        provide: I18NRouterLoader,
        useFactory: (i18nRouterFactory),
        deps: [Http, RAW_ROUTES]
      }
    ]),
    ...
  ],
  ...
  providers: [
    I18N_ROUTER_PROVIDERS,
	...
  ],
  ...
  bootstrap: [AppComponent]
})

I18NRouterHttpLoader has three parameters:

http: Http : Http instance
path: string : path to JSON file/API endpoint, to retrieve route translations from (by default, routes.json)
providedSettings: I18NRouterSettings : i18n-router settings
- routes: Routes: raw routes

Translations object

You can find detailed information about the data structure and usage guidelines for the translations object here.

Assuming that application settings are provided from ./routes.json, adding the following data to configuration file will provide route translations to @ngx-i18n-router/core through http.

routes.json

{
  "en": {
    "ROOT.ABOUT": "about",
    "ROOT.ABOUT.US": "us",
    "ROOT.ABOUT.BANANA": "banana",
    "ROOT.ABOUT.APPLE": "apple",
    "ROOT.ABOUT.APPLE.PEAR": "pear",
    "CHANGE_LANGUAGE": "change-language"
  },
  "tr": {
    "ROOT.ABOUT": "hakkinda",
    "ROOT.ABOUT.US": "biz",
    "ROOT.ABOUT.BANANA": "muz",
    "ROOT.ABOUT.APPLE": "elma",
    "ROOT.ABOUT.APPLE.PEAR": "armut",
    "CHANGE_LANGUAGE": "dil-secimi"
  }
