Users want apps to work offline. They expect instant updates. A local-first approach solves this.
You save data on the device first. The app syncs when you are online. CRDTs make this work.
CRDT means Conflict-Free Replicated Data Types. These structures merge data automatically. They remove the need for complex conflict rules. All users see the same state.
Use these tools for your stack:
- TypeScript and React
- Yjs for state management
- IndexedDB for local storage
- WebSockets for sync
Why use this method?
- It works offline.
- It allows real-time collaboration.
- It keeps data consistent across devices.
Two users edit a task at once. Standard apps overwrite one edit. CRDTs merge both edits. No data disappears.
