Strict null checks in TypeScript prevent runtime errors by forcing explicit handling of nullable values. You can implement them using optional chaining and nullish coalescing operators, ensuring robust null safety and explicit guards across your codebase.

To handle async patterns in TypeScript, apply consistent error handling, define explicit return types for async functions, and parallelize operations where appropriate. This ensures robust API contracts and maintainable internal utilities across frontend and backend code.

You need discriminated unions in TypeScript when modeling variant states, such as loading, success, and error responses. Combine these with explicit type guards to safely narrow types at runtime and enforce strict type discipline across your application.

Recommended TypeScript configuration settings for strict type checking include enabling strict null checks and configuring the tsconfig to enforce explicit public APIs and explicit return types. These settings provide practical patterns to improve overall type safety and maintainability.

To audit a TypeScript module for type safety, review its data structures and API contracts, replace 'any' with 'unknown', and add explicit return types to public APIs. This quick start approach immediately improves codebase robustness and maintainability.
