Updated Dec 30, 2025Main Prompt
Enable strict mode in my TypeScript configuration and fix all resulting type errors in my codebase. Please follow these steps: 1. Update tsconfig.json to include "strict": true 2. Identify all type errors that arise from this change 3. Fix each error with proper typing (avoid using 'any') 4. Add proper null checks where needed 5. Use type guards for runtime type checking where appropriate Additional strict options to consider: - noUncheckedIndexedAccess - noImplicitOverride - exactOptionalPropertyTypes
Optional Add-ons
Add stricter compiler options
Set up path aliases
Configure separate tsconfig files
Useful Notes
Start with 'strict: true' and add more options gradually
Use 'tsc --noEmit' to type-check without building
Consider using 'exactOptionalPropertyTypes' for stricter nullability
