React Native CRUD with Firebase and Firestore | Tutorial

Every real app needs create, read, update, and delete. Here you learn all four against a real-time database, building a product manager where changes show up instantly thanks to Firestore listeners. I build it from scratch in the video with Expo, React Navigation, and an emoji picker to give each product some personality.

If you've been wanting to connect React Native to a real backend, this is a solid first step.

What's inside

• Create a Firebase project and enable Firestore in test mode
• Connect your Expo app to Firebase with config keys
• Keep those keys out of source control with Expo Constants
• Navigate between a product list and a create screen with a stack navigator
• Add products with name, price, and an emoji picker
• Mark products as sold and delete them, with real-time UI updates
