Supabase Authentication Integration Broken
After Cursor refactored your Supabase authentication integration, login/signup stops working. Users cannot authenticate or their session isn't being maintained.
Supabase client initialization or auth flow was broken.
Error Messages You Might See
Common Causes
- Supabase client not initialized with correct URL and key
- signUp/signIn methods removed or refactored incorrectly
- Session management broken, not persisting auth state
- Auth listener not set up, session changes not detected
- Environment variables for Supabase not set
How to Fix It
Initialize client: createClient(url, anonKey). Sign up: await supabase.auth.signUp({email, password}). Listen to session: supabase.auth.onAuthStateChange(). Store session in state/context. Verify env vars NEXT_PUBLIC_SUPABASE_URL and _KEY.

I am a technologist and product builder dedicated to creating high-impact solutions at the intersection of AI and specialized markets. Currently, I am focused on PropScan (EstateGuard), an AI-driven SaaS platform tailored for the Japanese real estate industry, and exploring the potential of Archify.
As an INFJ-T, I approach development with a "systems-thinking" mindset—balancing technical precision with a deep understanding of user needs. I particularly enjoy the challenge of architecting Vertical AI SaaS and optimizing Small Language Models (SLMs) to solve specific, real-world business problems. Whether I'm in a CTO-level leadership role or hands-on with the code, I thrive on building tools that turn complex data into actionable value.

Get HelpFrequently Asked Questions
How do I persist auth across page reloads?
Supabase handles this. Call getSession() on app load to restore session from storage.
What's the difference between anon and service keys?
Anon key: client-side (safe to expose). Service key: server-side only (secrets). Use appropriate key based on context.
