Internationalization (i18n) is a must required feature for any modern web application. Internationalization enables the application to target any language in the world. Localization is a part of the Internationalization and it enables the application to render in a targeted local language. Angular provides complete support for internationalization and localization feature.
Let us learn how to use Internationalization in Angular by creating a simple hello world application in different languages.
Internationalization in Angular
Follow the steps given below to enable internationalization in Angular:
Step 1: Create a new Angular application using below command −
ng newi18n-sample
Step 2: Navigate to the app folder using the given command −
cd i18n-sample
Step 3: Change the AppComponent’s template as specified below −
<h2>{{ title }}</h2><div>Hello</div><div>The Current time is {{ currentDate | date :'medium'}}</div>
Step 4: Add localize module using below command −
ng add @angular/localize
Step 5: The LOCALE_ID is the Angular variable to refer the current locale. By default, it is set as en_US. Let us change the locale by using useValue: ‘hi’ (for Hindi) in the providers array of app.component.ts. Import the locale data from @angular/common/locales/hi and then, register it using registerLocaleData method. Also, define a local variable named CurrentDate and set current time using Date.now() as specified below:
import{ Component }from'@angular/core';import{ RouterOutlet }from'@angular/router';import{LOCALE_ID}from'@angular/core';import{ DatePipe, registerLocaleData }from'@angular/common';import localeHi from'@angular/common/locales/hi';registerLocaleData(localeHi); @Component({ selector:'app-root', standalone:true, imports:[RouterOutlet, DatePipe], providers:[{ provide:LOCALE_ID, useValue:'hi'}], templateUrl:'./app.component.html', styleUrl:'./app.component.css'})exportclassAppComponent{ title ='Internationalization Sample'; currentDate: number = Date.now();}
Step 6: Now run the application using ng serve command and check the result. You will see the date is specified using hi locale.

Finally, we have created a localized application in Angular.
