Supabase Pitfalls: Avoid These Common Mistakes for a Robust Backend​

Supabase offers a powerful open-source alternative to Firebase, built around PostgreSQL. Its ease of use makes it a favorite for rapid development, but this very convenience can lead developers down paths that introduce technical debt, performance bottlenecks, and security vulnerabilities. Understanding and avoiding these common pitfalls is crucial for building a robust and scalable application.

Writing docstrings in Python can feel like a chore - especially with the odd formatting involving triple quotes, >>> signs, and parameter blocks. But clear, standardized docstrings are critical for both readability and maintainability.

If you’re using VSCode (Visual Studio Code), you’re in luck. With a few extensions and configurations, you can make writing professional, PEP 257-compliant docstrings painless.

Writing clean and consistent code is a mark of professionalism, and it also makes collaboration easier. But keeping formatting consistent manually is hard. That’s where Black, the Python code formatter, shines.

Black automatically formats your code according to PEP 8 (Python’s style guide), with minimal configuration and zero fuss. This guide will show you how to install it, use it, and why it's helpful - especially if you're new to Python programming.

Off-by-one errors (OBOEs) are among the most common logic bugs, even for seasoned developers. These bugs occur when a loop or operation goes one iteration too far or one iteration too short-leading to incorrect results, missed elements, or crashes.

They usually occur in:

• Loops
• Array indexing
• Ranges
• Substring operations
