typescript

To enforce strict TypeScript patterns, apply const objects with as const, flat interfaces, unknown types, type guards, and utility types during development and code reviews to ensure type safety, readability, and maintainability across modules.

The best way to refactor scattered unions into a type-safe model is introducing a const-based types section, replacing complex inline types with flat interfaces, and adding type guards to validate runtime data for scalable projects.

Flat interfaces improve TypeScript maintainability by favoring single-level interfaces with references instead of inline nested objects, ensuring type safety and readability across modules during development.

You should prefer unknown over any for type safety practices because unknown forces explicit type checking through type guards and utility types, preventing unsafe runtime operations and ensuring safer code.

Yes, this approach works with existing TypeScript projects by adapting them through introducing a const-based types section, replacing complex inline types with flat interfaces, and adding type guards to validate runtime data.

You need to use type guards and utility types in TypeScript when avoiding the any type and preferring unknown, leveraging them to validate runtime data and enforce type safety for robust, maintainable code.
