Code Collab Editor

Inspiration

My inspiration was always having a difficult time collaborating with fellow peers whenever we had to program assignments for hw. Traditional development environments often lack real-time collaboration features, making it difficult for people to work on code for assignments together.

What it does

Code Collab Editor is a real-time collaborative code editing and execution tool. It lets you work with multiple users editing code simultaneously. It supports JavaScript and Python and has an AI assistant to assist with coding. It gives a live count showing when other participants are in your room and creates shareable room IDs to connect with others. It also includes file upload and download functionality.

How we built it

I built Code Collab Editor using Next.js 15:

1. Frontend:

   • Next.js React framework for the application structure
   • Monaco Editor (the engine behind VS Code) to include the code editor experience in the browser
   • Tailwind CSS for responsive styling

2. Backend:

   • Next.js API routes for server-side execution of code
   • Socket.IO for real-time collaboration
   • Node.js child processes for secure code execution

3. AI Integration:

   • Gemini API integration for code completion

4. Real-time Features:

   • Custom Socket.IO implementation for code synchronization
   • Indicators to show count for collaborative experience

Challenges we ran into

I had difficulty implementing secure code execution environments without risking server security. Socket.IO was essential in managing concurrent edits without conflicts or performance issues

Accomplishments that we're proud of

I am proud of the real-time code synchronization in an instant. It really made the collaborative experience responsive. I successfully implemented both client and server-side code execution, giving users flexibility while maintaining security.

What we learned

I learned mainly about designing systems that handle concurrent operations efficiently. I discovered methods to minimize network traffic to keep the app as responsive as possible

What's next for Code Collab Editor

I want to expand support for more programming languages like Java, Go, and C++. Implement version control to improve users' workflow. I would also like to add a chat and a cursor presence for users. Developing authentication and project management tools will be necessary for work between larger teams.
