🚀 CodeHack

LeetCode-Style DSA Practice Platform

🧠 Inspiration

We wanted to create a lightweight, LeetCode-style platform focused on making Data Structures and Algorithms (DSA) practice more accessible — especially for beginners. Most existing platforms require accounts or have steep learning curves. CodeHack offers a frictionless way to code, test, and learn — even anonymously.

💡 What it does

• 🧪 Users can solve DSA problems in C, C++, and Python
  
• 🧑‍💻 No login required – use a Demo Account to start instantly
  
• ✅ Submissions are tested against 5 predefined test cases
  
• ⚙️ View code efficiency and result feedback
  
• 📂 Track submissions and revisit your solutions
  
• 🎯 Clean, fast, and focused for pure coding practice

🛠️ How we built it

Tech Stack:

• Frontend: Next.js + Tailwind CSS
  
• Backend: Node.js with REST API
  
• Database: PostgreSQL + Prisma ORM
  
• Code Execution Engine: Judge0 API
  
• Hosting: Vercel

🧩 Challenges we ran into

• Handling multi-language code execution securely
  
• Ensuring reliable test case validation across all edge cases
  
• Building a UI that works both for registered and demo users
  
• Optimizing performance when compiling/running code on the backend

🏆 Accomplishments that we're proud of

• Built a real-time, interactive coding platform with live code execution
  
• Created a smooth, no-login-required user flow to reduce learning friction
  
• Added support for multiple programming languages
  
• Designed a system to provide instant test feedback and efficiency analysis

📚 What we learned

• Managing secure code execution with external APIs like Judge0
  
• Structuring problems, test cases, and scoring logic efficiently
  
• Creating seamless UI/UX that works across user types
  
• Balancing performance and functionality for code-heavy apps

🔮 What's next for CodeHack

• 🧠 Add AI-powered hints and code explanations
  
• 🎮 Launch a gamified challenge system (XP, levels, badges)
  
• 💬 Introduce community problem sharing
  
• 🏆 Add leaderboards and competitive contests
  
• 🔐 Explore plagiarism detection and smarter code analytics
