⚔️ CodeDuel - Competitive Coding Battles in VS Code

CodeDuel is a VS Code extension that lets you challenge your friends to real-time competitive programming duels — without ever leaving your editor.

🚀 Compete head-to-head by solving the same Codeforces problem
⏱ See who submits first and wins — results shown live in VS Code
👤 Log in with your Codeforces ID to get started

✨ Features

• 🔧 Start a Duel
  Use the VS Code Command Palette (Ctrl+Shift+P or Cmd+Shift+P) and run the Start Duel command. Share the generated Room ID with a friend.

• 🤝 Join a Duel
  Your friend runs the Join Duel command and enters the shared Room ID. Once both players are in, the duel begins.

• 💻 Same Problem, Same Time
  A random Codeforces problem is fetched for both players — everyone gets the exact same challenge.

• 📤 Codeforces Integration
  When you submit your solution on Codeforces, CodeDuel tracks the verdicts and updates the VS Code interface.

• 🏆 Live Winner Detection
  The first person to get an Accepted verdict wins the duel. A win/loss message is shown right in VS Code.

🔧 Setup

1. Install the extension from the VS Code Marketplace (Coming soon)
2. Open the Command Palette (Ctrl+Shift+P / Cmd+Shift+P)
3. Search for and run either:
   • CodeDuel: Start Duel
   • CodeDuel: Join Duel
4. You'll be prompted to enter your Codeforces handle (only once per session)
5. Let the games begin!

🖼️ Example Flow

1. Player A runs Start Duel → gets Room ID → shares it with Player B
2. Player B runs Join Duel → enters Room ID
3. Both receive the same Codeforces problem in their editor
4. They code and submit on Codeforces
5. CodeDuel checks every 10 seconds who got an AC first
6. Winner is announced inside VS Code 🎉

🛠️ Technologies Used

• VS Code Extension API
• Node.js backend (Socket.IO + Redis)
• Codeforces API
• Puppeteer/Selenium for Codeforces submission (optional automation)

📝 Notes

• Make sure you’re logged in to Codeforces before submitting your code.
• Extension does not store your credentials — only your Codeforces handle.
• You can continue solving the problem even after one player wins — great for practice!

📦 Future Plans

• Leaderboards & rating system
• Support for more platforms (e.g., LeetCode, AtCoder)
• Voice/chat feature during duels
• Custom problem difficulty filter
