Globalization in React DatePicker component

Globalization is the combination of internalization and localization. You can adapt the component to various languages by parsing and formatting the date or number Internationalization and also add culture specific customization and translation to the text localization.

By default, DatePicker date format, week, and month names are specific to the American 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. It provides the loadCldr method to load culture specific CLDR JSON data. To use a different culture other than English, follow the steps below:

  • Install the CLDR-Data package by using the following command (installs all the CLDR JSON data). To know more about CLDR-Data refer to the CLDR-Datalink.
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.ts file.

  • Now use the loadCldr method to load the culture specific CLDR JSON data from the installed location to app.ts 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.

import { loadCldr } from "@syncfusion/ej2-base";

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 numberingSystems from 'cldr-data/supplemental/numberingSystems.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);

if you are facing the error /node_modules/cldr-data/main/de/*.json (1,1): unused expression, expected an assignment or function call when you are adding the json files to render the culture sample, then add the below configuration in your tslint.json file

"linterOptions": {
    "exclude": [
      "*.json",
      "**/*.json"
    ]
  }
  

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 to a 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",
            today:"heute"
        }
    }
});
  • Set the culture by using the locale property. The below code example, initialize the DatePicker component in German culture with corresponding localized text.

The following example demonstrates the DatePicker in German culture.
