Closes #124
📝 Rationale / Motivation
This PR introduces multilingual support to the application using i18n (internationalization) and a language switcher, enabling users to interact with the platform in multiple languages.
This improves:
Accessibility for non-English users
User experience for a global audience
Scalability for adding new languages in the future
Separation of UI text from business logic for better maintainability
✨ Description of Changes
🌍 i18n Integration
Integrated i18n setup into the project
Added translation configuration and initialization layer
Structured translation files for scalable language support
📁 Translation System
Created language resource files (e.g., en.json, hi.json, etc.)
Moved all static UI text into translation keys
Replaced hardcoded strings with translation function (t())
🔄 Language Switcher
Added a language selector component in the UI
Supports switching languages dynamically without page reload
Stores selected language in localStorage (persistent preference)
🧠 State & Context Updates
Added i18n provider wrapper at app level
Ensured global access to language state across components
🖥️ UI Improvements
Updated navigation and key pages to support translations
Ensured consistent layout across different language lengths
🧪 Testing Instructions
Run the project locally:
npm install
npm run dev
Then:
Open the application
Locate the language switcher (header/settings/menu)
Switch between available languages
Verify:
UI text updates instantly
No page refresh is required
Selected language persists after reload
No missing translation keys appear in console/UI
🧪 Edge Case Testing
Switch language multiple times rapidly
Refresh page after changing language
Check fallback behavior for missing translation keys
Verify UI consistency for long translated strings
