Installation

We assume that you already installed ngx-translate.

Now you need to install the npm module for TranslateHttpLoader:

npm install @ngx-translate/http-loader --save

NB: if you're still on Angular <4.3, please use Http from @angular/http with [email protected].

Usage

1. Setup the TranslateModule to use the TranslateHttpLoader:

The TranslateHttpLoader uses HttpClient to load translations, which means that you have to import the HttpClientModule from @angular/common/http before the TranslateModule:

import {NgModule} from '@angular/core';
import {BrowserModule} from '@angular/platform-browser';
import {HttpClientModule, HttpClient} from '@angular/common/http';
import {TranslateModule, TranslateLoader} from '@ngx-translate/core';
import {TranslateHttpLoader} from '@ngx-translate/http-loader';
import {AppComponent} from "./app";

// AoT requires an exported function for factories
export function HttpLoaderFactory(http: HttpClient) {
    return new TranslateHttpLoader(http);
}

@NgModule({
    imports: [
        BrowserModule,
        HttpClientModule,
        TranslateModule.forRoot({
            loader: {
                provide: TranslateLoader,
                useFactory: HttpLoaderFactory,
                deps: [HttpClient]
            }
        })
    ],
    bootstrap: [AppComponent]
})
export class AppModule { }

The TranslateHttpLoader also has two optional parameters:

• prefix: string = "/assets/i18n/"
• suffix: string = ".json"

By using those default parameters, it will load your translations files for the lang "en" from: /assets/i18n/en.json.

You can change those in the HttpLoaderFactory method that we just defined. For example if you want to load the "en" translations from /public/lang-files/en-lang.json you would use:

export function HttpLoaderFactory(http: HttpClient) {
    return new TranslateHttpLoader(http, "/public/lang-files/", "-lang.json");
}

For now this loader only support the json format.
