Real-Time Chat App with Rooms
Socket.IO chat rooms with typing indicators, presence and history
1-2 weeks build
Overview
A browser chat app where users sign in, join public or invite-only rooms and talk in real time. Socket.IO carries messages, typing indicators and join or leave events, while MongoDB stores history so a returning user can scroll back through earlier messages. Presence shows who is online in each room, and unread counts update as messages arrive.
What makes it stand up
- 01Public and invite-only rooms with join, leave and member lists
- 02Typing indicators and online presence per room
- 03Persistent message history with cursor-based infinite scroll
- 04Unread counts and read receipts per room
- 05Reconnection handling that resends messages queued while offline
