When I used to discuss data-structure and algorithm problems with a friend while in college (yea thank covid for closing all the colleges D:), it was a pain in the neck since both of us were coding on different computers and different code-editors, and more often than not resorted back to just using pen and paper.

I attempted to solve this problem by creating a real-time collaborative editor in which once you enter a room you just need to share the URL with a friend and he can join your room and both of you can collaborate together.

Technologies used:

  • React for the front-end of caucus.
  • NodeJS for the back-end of caucus.
  • Postgresql database for storing and retrieving leetcode questions.
  • socket.io for real-time communication.
  • convergence for handling real-time collaboration.
  • Heroku🤮(I hate Heroku) for hosting the nodejs server and Azure 🥰 for hosting the docker container.

Features

  • Real-time collaboration for practicing for coding interviews
  • All free leetcode questions to practice.
  • You can also load any question from codeforces or atcoder by pasting the problem URL
  • Real-time messaging.
  • Remote code execution in 5 different languages (C++, Java, Python, Javascript and GO. Try it live: live demo
