@ngx-i18n-router/config-loader provides route translations to @ngx-i18n-router/core using @ngx-config/core, and helps reducing the amount of HTTP requests during application initalization by including route translations within the application settings - if @ngx-config/core is already used to retrieve settings by the Angular app.

NOTICE

This 5.x.x branch is intented to work with @angular v5.x.x. If you're developing on a later release of Angular than v5.x.x, then you should probably choose the appropriate version of this library by visiting the master branch.

Settings

Setting up I18NRouterModule to use I18NRouterConfigLoader

I18NRouterConfigLoader uses @ngx-config/core to load route translations.

  • Import ConfigModule using the mapping '@ngx-config/core' and append ConfigModule.forRoot({...}) within the imports property of app.module.
  • Import I18NRouterModule using the mapping '@ngx-i18n-router/core' and append I18NRouterModule.forRoot({...}) within the imports property of app.module.
  • Import I18NRouterConfigLoader using the mapping '@ngx-i18n-router/config-loader'.

Note: Considering the app.module is the core module in Angular application.

app.module.ts

...
import { HttpClient } from '@angular/common/http';
import { ConfigModule, ConfigLoader, ConfigHttpLoader } from '@ngx-config/core';
import { I18NRouterModule, I18NRouterLoader, I18N_ROUTER_PROVIDERS, RAW_ROUTES } from '@ngx-i18n-router/core';
import { I18NRouterConfigLoader } from '@ngx-i18n-router/config-loader';
...

export function configFactory(http: HttpClient): ConfigLoader {
  return new ConfigHttpLoader(http, './config.json');
}

export function i18nRouterFactory(config: ConfigService, rawRoutes: Routes): I18NRouterLoader {
  return new I18NRouterConfigLoader(config, 'routes', {routes: rawRoutes});
}

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

I18NRouterConfigLoader has three parameters:

  • config: ConfigService : ConfigService instance
  • group: string : group key, to fetch route translations from applcation settings (by default, routes)
  • 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 ./config.json, adding the following data to configuration file will provide route translations to @ngx-i18n-router/core through @ngx-config/core.

config.json

{
  ...
  "routes": {
    "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"
    }
  },
  ...
}

:+1: Well! @ngx-i18n-router/config-loader will now provide route translations to @ngx-i18n-router/core using @ngx-config/core.
