@formatjs/intl-localematcher
Advanced tools
The @formatjs/intl-localematcher package is designed to help with locale matching based on the Best Fit Matcher algorithm as specified by the ECMAScript Internationalization API. It allows developers to determine the best available locale for their application based on a list of desired locales and a list of supported locales. This can be particularly useful in internationalization (i18n) efforts where applications need to gracefully handle multiple languages and regional differences.
Locale Matching
This feature allows you to match a list of desired locales against a list of supported locales to find the best match. It uses the Best Fit Matcher algorithm to determine the most appropriate locale for the user.
"use strict";
const {getCanonicalLocales, match} = require('@formatjs/intl-localematcher');
const supportedLocales = ['en-US', 'fr-FR', 'es-ES'];
const desiredLocales = ['en-GB', 'en'];
const bestMatch = match(desiredLocales, supportedLocales);
console.log(bestMatch); // 'en-US'The 'locale' package provides similar functionalities for locale detection and negotiation. It can parse, normalize, and match locales using different strategies. Compared to @formatjs/intl-localematcher, 'locale' offers a broader set of features for handling locales but might not specifically implement the Best Fit Matcher algorithm as defined by ECMAScript.
This package is designed to parse the Accept-Language header from an HTTP request and match it against a list of supported languages. While it serves a similar purpose in determining the best language for the user, it is more focused on the context of HTTP requests and does not directly implement the ECMAScript Internationalization API's Best Fit Matcher algorithm.
