intl-locale-textinfo-polyfill
This library will help you to detect if the locale is right-to-left language or not.
It implements part of this now Stage 3 intl-locale-info proposal.
The library has begun as a fork of rtl-detect,
but it strives to adhere to the Intl.Locale (textInfo) proposal (notably,
locales with underscores as in the form en_US are not accepted).
Usage
import the library as a ponyfill
import Locale from 'intl-locale-textinfo-polyfill';
const { direction } = new Locale('he').textInfo;
// "rtl"import the library as a polyfill
import 'intl-locale-textinfo-polyfill/lib/polyfill.js';
const { direction } = new Intl.Locale('he').textInfo;
// `direction` will be "rtl"Intl.Locale#textInfo
This returns an object with the language direction for the locale.
Examples:
const { direction } = new Intl.Locale('ar-JO').textInfo;
// `direction` will be "rtl"const { direction } = new Intl.Locale('ar').textInfo;
// `direction` will be "rtl"const { direction } = new Intl.Locale('en-US')).textInfo;
// `direction` will be "ltr"
