Renovating a vibe-coded app: the code was readable, the reasoning was gone
TL;DR
A renovation of a vibe-coded education app revealed that while the code was readable, the underlying business logic was unclear, particularly regarding the definition of 'citizenship'. This lack of clarity led to uncertainty in implementing changes to the app's functionality.
✦ Why It Matters
Ensure all business logic is clearly documented to avoid ambiguity in future code changes.
Key Takeaways
- Document business logic clearly to avoid ambiguity.
- Regularly audit code for security vulnerabilities.
- Establish clear ownership of scoring algorithms.
- Implement a robust migration strategy for database changes.
Full Summary
An education platform was built using Supabase for the backend and React for the frontend, focusing on scoring students based on effort rather than test results. During a renovation, the author encountered a function for cleaning duplicate citizenship records, but the term 'citizenship' was undefined in the codebase or documentation.
After addressing various migration issues and security vulnerabilities, the author discovered conflicting scoring mechanisms that could lead to inconsistent student grades. Despite the app being operational, the absence of clear reasoning behind decisions made during development posed risks for future changes.
The project highlighted the importance of maintaining comprehensive documentation to ensure clarity and accountability in software development.
