Booth-Chat : A full-stack chat-room app hackathon

Goal

Build a Robust Multi-Tenant Node.js Server Application using modern web technologies. The focus is really on the server-side application.

• Express web framework using Typescript
• SQLite database with raw SQL
• Asynchronous REST APIs
• Use of middleware for JWT token authentication. No framework is used
• WebSocket (socket.io) for push notifications
• Proper error handling to make server production hardened
• Docker and Nginx
• Cloud deploy to Heroku and Vercel
• Interaction using a React-UI frontend

Server requirements for multi-tenant chat room

• Ability to register new users
• Create/delete rooms
• Join/leave rooms
• Broadcast messages within rooms
• Message history persistence
• Recover state from database on restart
• Support users joining from multiple devices.

Architecture

Demo/Deployment

1. The NodeJS application is deployed on Heroku using docker. I used the same port for both http and websocket because I don't know how to set multiple ports for Heroku.
2. The React front-end is deployed on Vercel.
