browser-localization-detector

This library provides a simple and efficient way to detect the preferred language of a user's browser in a Node.js environment. It utilizes the accept-language-parser library to parse the Accept-Language header of an HTTP request and extract the user's preferred language.

Installation

npm install browser-localization-detector

Usage

const detectPreferredLanguage = require('browser-localization-detector');

// Example usage in an Express.js route handler
app.get('/', (req, res) => {
  const preferredLanguage = detectPreferredLanguage(req);
  res.send(`Your preferred language is: ${preferredLanguage}`);
});

API

detectPreferredLanguage(req)

• req: HTTP request object.

Returns the user's preferred language code based on the Accept-Language header of the provided request object (req). If no language is detected, null is returned.

Example

const express = require('express');
const detectPreferredLanguage = require('browser-localization-detector');

const app = express();

app.get('/', (req, res) => {
  const preferredLanguage = detectPreferredLanguage(req);
  res.send(`Your preferred language is: ${preferredLanguage}`);
});

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});

Note

This library is designed to be used in a Node.js environment and does not support browser-side JavaScript. If you require browser-side localization detection, consider using libraries such as i18next in conjunction with i18next-browser-languagedetector.
