Goodbye Moment, Hello Luxon: Modern Date-Time Handling with Dynamic Locale Support #luxon #MomentJS

🚀 Goodbye Moment.js, Hello Luxon! | React Native Date-Time Migration Tutorial 🔥

In this video, we walk you through how we migrated from Moment.js to Luxon in our React Native project, implemented dynamic locale support, and removed bulky, outdated date-time libraries.

🧠 Why the change?
Moment.js is officially in maintenance mode — it's large, mutable, and lacks modern features like tree-shaking and native Intl support. Luxon brings everything Moment lacks — immutability, modern APIs, timezone support, and clean internationalization.

🌐 What You'll Learn:

Why we replaced Moment.js with Luxon

How to format dates and times using Luxon

Parsing and converting dates with dynamic timezones

Fixing toLocaleString inconsistencies across iOS, Android & Web

Building a custom fallback for iOS using regex and format inference

Migrating without breaking user experience on 100+ locales

📦 Packages Removed:
moment
moment-timezone
moment-business-days

🔁 Replaced with:
npm install luxon
📲 Platform Support:
✅ Web
✅ Android
⚠️ iOS (with workaround for Intl limitations)

💡 BONUS: Includes a detectLuxonFormatFromInput utility to dynamically infer and parse date-time strings based on user locale!
