How to implement localization in Angular 2 Plus

A locale denotes region in which application is running and identifies that region where people speak a particular language.

We will add localization in angular application using ngx-translate/core package. let's understand how to use it step by step.

Step 1: Install ngx-translate/core package in your app using following command.

     npm i @ngx-translate/core

Step 2: Import package in app module 

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

After this, add TranslateModule in import array of app module as below

      loader: {
        provide: TranslateLoader,
        useFactory: HttpLoaderFactory,
        deps: [HttpClient]
      defaultLanguage: 'en'

Step 3: Create a folder i18n in assets folder and create seprate json files of your languages as below.

Step 4: Now it's time to add translation for texts where you want to add it.

If you want to add this in html file, you can use as following.

{{'HOME.MESSAGE' | translate}} // here translate is a pipe

// HOME.MESSAGE is denoting keys of your json file as following


    "HOME": {

        "MESSAGE": "Some Message"



If you want to add translation in component, you can do the same as following.

            private translate: TranslateService)

These are the simple steps to follow and you will have a application with Internationalization, you can publish your app in multiple languages if you need it.
