Stress-Test Your Atcoder Problems Online - v2

Exciting News! Version 2 is now live! 🚀
( *Main branch contains the prototype )

---

🔍 Overview

This microservice tool streamlines the debugging process for AtCoder problems by leveraging platform test cases and user inputs. It isolates each test case, dry-runs your code, retrieves the expected output, and compares it with editorial solutions. This iterative process helps quickly identify discrepancies, pinpoint failing test cases, and makes debugging much easier.

🛠️ Tech Stack

• Backend: Golang, Node.js, REST API .
• Frontend: Next.js, TailwindCSS, Bootstrap
• Integrations ( to be added ) : Redis , mongoDB and Docker .

⚙️ System Architecture

1. Frontend: User interface for submitting code and viewing results.
2. Backend: Composed of multiple services:
   • api-gateway (apiGate) - Routes requests.
   • cs1 & cs2 - Worker servers responsible for handling compilation and test execution.
   • subCode - Web scraping server fetching test cases from AtCoder.

System Flow:

Frontend ➡️ subCode (Web Scraping) ➡️ Frontend ➡️ apiGate (API Gateway) ➡️ cs1 & cs2 (Worker Servers) ➡️ apiGate ➡️ Frontend

💻 How to Use

Just enter the submission link and you are good to GO !

🚧 Current Limitations

1. Delay in Response time: Since the api gateway , worker-servers and code scrapping servers are hosted in Render's free service , so the services generally spins down due to inactivity and takes around 1-2 minutes to spin back again.
2. Manual Contest Links: Contest links must be manually added to our database due to web scraping issues, resulting in a short delay after each contest before test cases are added.
3. Variable Line Support: Does not support test cases with variable lines of input or output yet.

🎯 Future Targets

• Custom Test Cases: Add functionality for users to write custom test cases for faster debugging.
• AI-Powered Separation: Explore AI-powered tools to automate the separation of test cases, removing reliance on manual input.
• Previous Submissions: Implement features to track and manage users' previous submissions on AtCoder.
