Angular10 getLocaleId() Function

In this article, we are going to see what is getLocaleId in Angular 10 and how to use it.

The getLocaleId is used to get the locale ID from the current locale.

Syntax:

getLocaleId(locale: string): string

NgModule: Module used by getLocaleId is:

• CommonModule

Approach:

• Create the angular app to be used
• In app.module.ts import LOCALE_ID because we need locale to be imported for using get getLocaleId.

import { LOCALE_ID, NgModule } from '@angular/core';

• In app.component.ts import getLocaleId and LOCALE_ID
• inject LOCALE_ID as a public variable.
• In app.component.html show the local variable using string interpolation
• serve the angular app using ng serve to see the output.

Parameters:

• locale: the locale code

Return value:

• string: the locale code.

Example 1:

app.module.ts

import { LOCALE_ID, NgModule }
        from '@angular/core';
import { BrowserModule }
        from '@angular/platform-browser';

import { AppRoutingModule }
        from './app-routing.module';
import { AppComponent }
        from './app.component';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    AppRoutingModule
  ],
  providers: [
      { provide: LOCALE_ID, useValue: 'en-GB' },
  ],
  bootstrap: [AppComponent]
})
export class AppModule { }

app.component.ts

import {FormStyle,
        getLocaleId,
        TranslationWidth}
        from '@angular/common';

import { Component,
         Inject,OnInit,
         LOCALE_ID }
         from '@angular/core';

@Component({
    selector: 'app-root',
    templateUrl: './app.component.html'
})
export class AppComponent {
    for = getLocaleId(this.locale);
    constructor(
        @Inject(LOCALE_ID) public locale: string,){}
