What are the steps to globalize the ng-bootstrap datepicker?

For my current project, I am utilizing the ng-bootstrap datePicker component. The demo for my simple datePicker widget can be found here.

However, I am now seeking to internationalize it by setting it to use the Russian language. Any assistance with this would be greatly appreciated.

Here is the JavaScript code snippet:

import {Component} from '@angular/core';
import {NgbDate, NgbCalendar} from '@ng-bootstrap/ng-bootstrap';

@Component({
  selector: 'ngbd-datepicker-range',
  templateUrl: './datepicker-range.html',
  styles: [``]
})
export class NgbdDatepickerRange {

  hoveredDate: NgbDate;

  fromDate: NgbDate;
  toDate: NgbDate;

  constructor(calendar: NgbCalendar) {
    this.fromDate = calendar.getToday();
    this.toDate = calendar.getNext(calendar.getToday(), 'd', 10);
  }

  onDateSelection(date: NgbDate) {
    if (!this.fromDate && !this.toDate) {
      this.fromDate = date;
    } else if (this.fromDate && !this.toDate && date.after(this.fromDate)) {
      this.toDate = date;
    } else {
      this.toDate = null;
      this.fromDate = date;
    }
  }

  isHovered = (date: NgbDate) => this.fromDate && !this.toDate && this.hoveredDate && date.after(this.fromDate) && date.before(this.hoveredDate);
  isInside = (date: NgbDate) => date.after(this.fromDate) && date.before(this.toDate);
  isRange = (date: NgbDate) => date.equals(this.fromDate) || date.equals(this.toDate) || this.isInside(date) || this.isHovered(date)
}

Answer №1

Alright, here is the solution I came up with: https://stackblitz.com/edit/angular-dd3vve?file=app/datepicker-range.ts

Based on this demo as reference, here are the changes I made:

// Extending NgbDatepickerI18n in the class definition
export class NgbdDatepickerRange extends NgbDatepickerI18n {

.

// Calling super() within the constructor
constructor(calendar: NgbCalendar) {
  super()

.

// Implementing the abstract methods
getWeekdayShortName(weekday: number): string {return "td"};
getMonthShortName(month: number): string {return "mt"};
getMonthFullName(month: number): string {return "month"};
getDayAriaLabel(date: NgbDateStruct): string {return "e"};

.

// Providing in the component
@Component({
  selector: 'ngbd-datepicker-range',
  templateUrl: './datepicker-range.html',
  providers: [{provide: NgbDatepickerI18n, useClass: NgbdDatepickerRange}],

You will need to adjust the method implementations to return appropriate values.

If you want to set up locale in your Angular application, the following code snippet can be used:

import { LOCALE_ID } from '@angular/core';
import { registerLocaleData } from "@angular/common";
import localeRo from "@angular/common/locales/ro";
import localeRoExtra from "@angular/common/locales/extra/ro";

registerLocaleData(localeRo, "ro", localeRoExtra);

After that, provide the locale ID in the @NgModule decorator like this:

providers: [{ provide: LOCALE_ID, useValue: "ro-RO"}]

No need to use NgbDatepickerI18n for this purpose!
