Internationalization Library Usage Guide

This README provides an overview of how to use the internationalization library in your project to support multiple languages.

Overview

The internationalization library allows you to easily add multilingual support to your application. It provides features for loading translation files, setting the default language, and switching between supported languages.

Installation

Before using the internationalization library, you need to install it as a dependency in your project. You can do this using npm:

npm install i18next i18next-fs-backend

Usage

1. Importing Libraries: In your JavaScript file, import the necessary libraries:

   const i18next = require('i18next');
   const Backend = require('i18next-fs-backend');
   const path = require('path');

2. Initialization: Initialize the internationalization library with the desired configuration options:

   i18next
       .use(Backend)
       .init({
           backend: {
               loadPath: path.join(__dirname, 'locales', '{{lng}}', '{{ns}}.json')
           },
           lng: 'en',
           fallbackLng: ['en', 'zh'],
           debug: true
       });

3. Setting Language: Set the default language for your application:

   i18next.changeLanguage('en', (err, t) => {
       // Current language is English
   });

4. Switching Language: You can switch the language dynamically during runtime:

   i18next.changeLanguage('fr', (err, t) => {
       // Current language is French
   });

Additional Notes

• The library supports loading translation files from different directories. Make sure to specify the correct path in the configuration.
• Debug mode is enabled by default, which provides additional logging information. You can disable it by setting debug: false.
• Ensure that the specified languages in the fallbackLng array match the available translation files.
