Modern teams want instant updates. Nobody wants to refresh a page to see a task move. You want your software to feel fast.
Build a real-time Kanban board with React, TypeScript, and WebSockets.
The stack:
- Frontend: Vite, React DnD, Zustand.
- Backend: Node.js, Express, Socket.IO.
- Database: PostgreSQL.
Avoid polling. Polling asks the server for updates every few seconds. It wastes resources. It slows down the app.
Use WebSockets. WebSockets keep a connection open. The server pushes updates to you. You get lower latency.
Organize your code by features. Do not use one giant components folder. Use folders for:
- api
- components
- features
- hooks
- store
- types
TypeScript prevents bugs. Zustand keeps state simple. React DnD handles task movement.
Use optimistic updates. Update the UI before the server responds. If the server fails, roll back the change. This makes the app feel instant.
Stop data conflicts with versioning. Give each task a version number. Only accept updates with a newer version.
Keep the app fast. Use React.memo for components. Select only the state you need.
Safety comes first. Always verify permissions on the server. Never trust the frontend. Handle offline states with banners.
Start with these steps:
- Build the board.
- Add drag and drop.
- Add WebSockets.
- Handle conflicts.
- Optimize performance.
