• Installation
• Usage

breaking change: v9.0.0

• This library is now using httpBackend instead of the httpClient, to avoid being delayed by interceptor, which was creating errors while loading.
• From the v9, the library will only be using a list of string[] so prefix & suffix aren't needed anymore and .json gonna be the default suffix.

Installation

We assume that you already installed ngx-translate.

Now you need to install the npm module for MultiTranslateHttpLoader:

npm install ngx-translate-multi-http-loader --save

Choose the version corresponding to your Angular version:

Angular	@ngx-translate/core	ngx-translate-multi-http-loader
14	14.x+	8.x+
13	14.x+	7.x+
6	10.x+	1.x+

Usage

The MultiTranslateHttpLoader uses HttpBackend to load translations, therefore :

• Create and export a new HttpLoaderFactory function
• Import the HttpClientModule from @angular/common/http
• Setup the TranslateModule to use the MultiTranslateHttpLoader

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

// AoT requires an exported function for factories
export function HttpLoaderFactory(_httpBackend: HttpBackend) {
    return new MultiTranslateHttpLoader(_httpBackend, ['/assets/i18n/core/', '/assets/i18n/vendors/']);
}

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

The MultiTranslateHttpLoader takes a list of strings.

Those strings, for example ['/assets/i18n/core/', '/assets/i18n/vendors/'],
will load your translations files for the lang "en" from : /assets/i18n/core/en.json and /assets/i18n/vendors/en.json

The loader will merge all translation files from the server using deepmerge.
