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 { }

angular-l10n
angular-l10n is another library for localization in Angular applications. It provides similar functionalities to @ngx-translate/http-loader, such as loading translation files and managing translations. However, it also includes additional features like locale management and date/number formatting.
angular-translate
angular-translate is a popular library for AngularJS (Angular 1.x) that provides similar functionalities to @ngx-translate/http-loader. It allows loading translation files via HTTP and managing translations. However, it is designed for AngularJS and not for Angular (2+).
@ngx-translate/http-loader
A loader for ngx-translate that loads translations using http.

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 http-loader@0.1.0.
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";
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.
