Angular 2 - Multilingual Support

问题

We are using Angular 2.0 in our Application. In that application we want to give multilingual support.We know using angular 1.0 how to implement. but don't know how to use in 2.0.

回答1:

I can recommend ngx-translate library, it's very easy to integrate and use.

1. Install via npm

npm install @ngx-translate/core --save

2. Add TranslateModule in app.module.ts imports

import {TranslateModule} from '@ngx-translate/core';

@NgModule({
   declarations: [...],
   imports     : [TranslateModule.forRoot(), ...],
   exports      : [...],
   providers   : [...],
   bootstrap   : [AppComponent]
})

export class AppModule {}

3. app.components.ts

import {Component} from '@angular/core';
import {TranslateService} from '@ngx-translate/core';

@Component({
  selector   : 'app',
  templateUrl: './app.component.html',
})
export class AppComponent {
  constructor(private translate: TranslateService) {
    translate.addLangs(['en', 'hy']);
    translate.setDefaultLang('en');
    translate.use('en');
  }
  changeLang(lang: string) {
    this.translate.use(lang);
  }
}

4. app.component.html

<nav>
  <a [routerLink]="['/']">    
    {{ "home" | translate }}
  </a>
  |
  <a [routerLink]="['/about']">
    {{ "about" | translate }}
  </a>
  |
  <a [routerLink]="['/contact']">
    {{ "contact" | translate }}
  </a>
</nav>
<div class="lang-bar">
  <a (click)="changeLang('en')">EN</a>
  <a (click)="changeLang('hy')">ՀՅ</a>
</div>

5. Create i18n folder with translation files

en.json

{
    "home" : "Home",
    "about" : "About",
    "contact" : "Contact"
}

hy.json

{
    "home" : "Գլխավոր",
    "about" : "Մեր մասին",
    "contact" : "Հետադարձ կապ"
}

回答2:

i18n in Angular2 is still work in progress and seems not yet to be usable.
