Globalization in Vue DatePicker component

30 Mar 2021 / 4 minutes to read

Globalization is the combination of adapting the component to various languages by means of parsing and formatting the date or number Internationalization and also by adding cultural specific customizations and translating the text localization

By default, DatePicker date format, week and month names are specific to English culture. It utilizes the Essential JavaScript 2 Internationalization package to parse and format the date object based on the culture by using the official UNICODE CLDR JSON data and it allows to load the culture specific CLDR JSON data by using loadCldr method

The DatePicker component supports only the Gregorian type of calendar. All the Essential JS 2 component are specific to English culture (‘en-US’). If you want to go with the different culture other than English, follow the below steps.

Install the CLDR-Data package by using the below command (it installs the CLDR JSON data). To know more about CLDR-Data refer the CLDR-Data link.

npm install cldr-data --save

Once the package installed, you can find the culture specific JSON data under the location \node_modules\cldr-data.

Now import the installed CLDR JSON data into the app.vue file.
Now use the loadCldr method to load the culture specific CLDR JSON data from the installed location to app.vue file.
DatePicker displayed Sunday as the first day of week based on default culture (“en-US”). If you want to display the DatePicker with loaded culture’s first day of week, you need to import weekdata.json file from the cldr-data/suppemental as given in the code example.

//Load the loadCldr from ej2-base
import { loadCldr } from '@syncfusion/ej2-base';

import * as numberingSystems from 'cldr-data/supplemental/numberingSystems.json';
import * as gregorian from 'cldr-data/main/de/ca-gregorian.json';
import * as numbers from 'cldr-data/main/de/numbers.json';
import * as timeZoneNames from 'cldr-data/main/de/timeZoneNames.json';
import * as weekData from 'cldr-data/supplemental/weekdata.json';// To load the culture based first day of week

loadCldr(numberingSystems, gregorian, numbers, timeZoneNames, weekData);

The Localization library allows you to localize default text content of the DatePicker. The DatePicker component has static text for today feature that can be changed to other cultures (Arabic, Deutsch, French, etc.) by defining the locale value and translation object.

Locale keywords	Text
today	Name of the button to choose Today date.
placeholder	Hint to describe expected value in input element.

Before changing the culture other than English, ensure that locale text for the concerned culture is loaded through load method of L10n class.

//Load the L10n from ej2-base
import { L10n } from '@syncfusion/ej2-base';

//load the locale object to set the localized placeholder value
L10n.load({
'de': {
    'datepicker': { placeholder: 'Wählen Sie ein Datum aus', today: 'heute' }
}
});

Set the culture by using the locale property. The following example demonstrates the DatePicker in German culture.
