Prevent TypeScript type drift between database and frontend by auditing for duplicate type definitions and unanchored interfaces. Prune redundant types and ensure all AppXxx frontend types derive directly from Supabase-generated DbXxx types to maintain a single source of truth.

Using 'any' and 'as' in TypeScript breaks type safety by bypassing the compiler's strict checks, allowing unvalidated runtime data to flow into your frontend. Audit your codebase to remove generic 'any' usage and validate API responses against Supabase types to prevent runtime errors.

The best way to validate runtime API responses against Supabase-generated TypeScript types is to audit your API routes for improper type derivations. Enforce strict type flows from the database layer and validate runtime data to ensure it matches the generated database.types.ts definitions.

Yes, you can audit an existing TypeScript codebase for duplicate type definitions and unanchored interfaces. The audit identifies anti-patterns, detects duplicate types across API routes and frontend layers, and generates a plan to align all types with Supabase database definitions.

Yes, this approach works for fixing type errors across database, API route, and frontend layers simultaneously. It applies strict typing rules across your entire stack, checking generic 'any' usage, duplicate types, and improper derivations to enforce consistent type flows from database to UI.
