@ngx-translate/http-loader

What is @ngx-translate/http-loader?

@ngx-translate/http-loader is an Angular library that provides a way to load translation files from a web server using HTTP. It is used in conjunction with @ngx-translate/core to manage internationalization in Angular applications.

What are @ngx-translate/http-loader's main functionalities?

Loading Translation Files

This feature allows you to load translation files from a web server. The TranslateHttpLoader uses Angular's HttpClient to fetch translation files, which are typically in JSON format.

import { HttpClient } from '@angular/common/http';
import { TranslateHttpLoader } from '@ngx-translate/http-loader';

export function HttpLoaderFactory(http: HttpClient) {
  return new TranslateHttpLoader(http);
}

Custom File Paths

You can customize the path and file extension of the translation files. This example shows how to set a custom path and file extension for the translation files.

import { HttpClient } from '@angular/common/http';
import { TranslateHttpLoader } from '@ngx-translate/http-loader';

export function HttpLoaderFactory(http: HttpClient) {
  return new TranslateHttpLoader(http, '/assets/i18n/', '.json');
}

Using with TranslateModule

This feature demonstrates how to integrate the TranslateHttpLoader with the TranslateModule in an Angular application. The HttpLoaderFactory is used to configure the loader for the TranslateModule.

import { HttpClient } from '@angular/common/http';
import { TranslateLoader, TranslateModule } from '@ngx-translate/core';
import { HttpLoaderFactory } from './http-loader.factory';

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

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

Usage

1. Setup the TranslateModule to use the TranslateHttpLoader:

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

import {NgModule} from '@angular/core';
import {BrowserModule} from '@angular/platform-browser';
import {HttpModule, Http} from '@angular/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: Http) {
    return new TranslateHttpLoader(http);
}

@NgModule({
    imports: [
        BrowserModule,
        HttpModule,
        TranslateModule.forRoot({
            loader: {
                provide: TranslateLoader,
                useFactory: HttpLoaderFactory,
                deps: [Http]
            }
        })
    ],
    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: Http) {
    return new TranslateHttpLoader(http, "/public/lang-files/", "-lang.json");
}

For now this loader only support the json format.
