Collaborative Code Reviewer

A real-time collaborative code review platform built with a microservices architecture. Multiple users can join shared rooms, write code together, analyze it with a linter, and leave comments — all in real time.

Features

• Real-time collaborative code editing (Socket.io)
• Python analysis via Pylint (real lint errors and warnings)
• JavaScript analysis via custom regex rules (var, ==, console.log, debugger, etc.)
• Live comment panel per room
• JWT-based authentication
• Room creation and joining via lobby page
• Dark gradient UI with Monaco Editor

Getting Started

Prerequisites

• Docker Desktop
• MongoDB Atlas account (or any MongoDB URI)

Setup
