## Building a Real-Time Collaborative App – Part 1: Chat Done Right 💬

Creating a real-time chat system from scratch using WebSockets, Prisma, and PostgreSQL.

I'm building a full-stack collaborative app inspired by tools like Notion and Slack. The vision? Real-time chat, shared documents, and even AI features like summarizing and explaining content.

This is Part 1 of the journey — where I built the chat system that powers real-time communication between users in the same room.

🛠️ Tech Stack

• 
  Frontend: React + Tailwind CSS


• 
  Backend: Node.js + Express


• 
  Database: PostgreSQL (via Neon)


• 
  ORM: Prisma


• 
  WebSocket: ws library

✨ Features

• ✅ Signup / Login / Logout with JWT


• ✅ Join or create chat rooms


• ✅ Real-time messaging via WebSockets


• ✅ Typing indicators (who’s typing?)


• ✅ Messages stored in PostgreSQL


• ✅ Secure token-based auth

Each chat room works like a real-time space where users can message, see typing activity, and stay synced with others instantly.

🧠 Key Learnings

• 
  WebSocket architecture for multiple rooms requires clean message protocols and user-session tracking.


• 
  Prisma makes schema modeling and database integration straightforward.


• Building a custom typing indicator system was surprisingly fun!

🔮 What’s Next?

The chat system is just the beginning. Here’s what’s coming up:

• 📝 Collaborative documents with Tiptap + Hocuspocus
  


• 🤖 AI integration for:
  
  
  
  
  • Chat summarization
  
  
  • Contextual explanations of documents
  
  
  
  
  
  

This is shaping up to be a real-time, AI-powered team workspace tool.

Thanks for reading! This is part of a devlog-style series where I’ll be building the entire app in public. If you're interested in collaborative tools, AI integration, or full-stack dev, follow along. 🚀
