SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Audit TypeScript code for type-safety issues, anti-patterns, and duplicate type definitions. Use when fixing type errors, reviewing TypeScript code, auditing for "any" or "as" usage, checking for duplicate types, or ensuring Supabase types are used as source of truth.

Core Features & Use Cases

Enforce strict typing across database-to-frontend data flows.
Detect and prune duplicate type definitions and unanchored interfaces.
Validate API responses and runtime data against Supabase-generated types to prevent drift.

Quick Start

Audit a codebase for TypeScript type-safety issues and generate a plan to align Supabase DB types (DbXxx) from database.types.ts to AppXxx frontend types.

FAQPage Schema

How do I enforce strict TypeScript type safety from my Supabase database to the frontend UI?▼

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.

Why does using 'any' and 'as' in TypeScript break type safety in Supabase projects?▼

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.

What is the best way to validate runtime API responses against Supabase-generated TypeScript types?▼

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.

Can I audit my existing TypeScript codebase for duplicate type definitions and unanchored interfaces?▼

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.

Does this approach work for fixing type errors across database, API route, and frontend layers simultaneously?▼

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.
