Chat Application (WebSocket)

Part of the Frontend Developer Roadmap

In short

A real-time chat app using WebSockets — rooms/channels, typing indicators, and message history — a strong demonstration of real-time frontend skills.

How to learn this

  1. 1Implement typing indicators and online/offline presence.
  2. 2Handle reconnection gracefully if the WebSocket connection drops.
  3. 3Add message persistence so chat history survives a refresh.
