intl-locale-textinfo-polyfill

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"
