Nice App!
More better if you include a database like Mongodb

Nice, I have also build a Realtime code editor project using socket.io calledCode-Sync.

🔮 Features of the project:

• 💻 Real-time collaboration on code editing across multiple files
• 🚀 Unique room generation with room ID for collaboration
• 🌈 Syntax highlighting for various file types with auto-language detection
• 💡 Auto suggestion based on programming language
• ⏱️ Instant updates and synchronization of code changes across all files
• 📣 Notifications for user join and leave events
• 🎨 Multiple themes for personalized coding experience
• 🌍 Comprehensive language support for versatile programming
• 🔠 Option to change font size and font family
• 👥 User presence list of users currently in the collaboration session, including online/offline status indicators
• 📁 Open, edit, save, and delete file functionalities
• 💾 Option to download files edited within the collaboration session
• 💬 Group chatting allows users to communicate in real-time while working on code.
• 🎩 Real-time tooltip displaying users currently editing
• 🚀 Code Execution: Users can execute the code directly within the collaboration environment, providing instant feedback and results.
