Finally completed my own collaborative WEB IDE. Inspired by Replit.com
Features:

• Contarized Playground Execution using Docker

• Real Time Multi User Cursor Tracker, and Chat using Socket-IO

• Pseudao Terminal using Node-PTY and Xterm.

• Code suggestion based on language using Monaco Editor

• Persist project storage using Docker Volume.

• MongoDB for persisting user and project data.
  

Challenges Faced:

• Realtime multi cursor update in Monaco editor based on files and user viewing same file without any external library. Achieved this functionality using Monaco Decorations, Real time Socket-IO and effective use of React state and memoization.

• Configuring Pseudo Terminal for project, unabling user to install libraries.

• Executing Build projects from docker container to user.

Area To Improve:

• Using proper Container Orchestration like Kubernetes instead of relaying on backend and Dockerode package. It will make it easier for exposing ports.

• Executing project inside IDE page using iFrame instead of opening it in new Tab.
