typescript

Use const objects to derive union types, creating a single source of truth for runtime values. This const-first pattern ensures your TypeScript code remains synchronized between the literal values and their type definitions, preventing mismatches during refactoring.

The best way to handle unknown types is to use the unknown type instead of any, combined with dedicated type guards. This requires you to validate inputs before use, ensuring type safety and eliminating the runtime risks associated with using any.

Structure flat interfaces by keeping them one-level deep and using proper extension to avoid inline complex types. This practice encourages composing strong interfaces through standard utility types like Pick, Omit, and Partial instead of nesting complex definitions.

Use Import Type and utility types across modules, components, and libraries to compose strong data shapes safely. Import Type ensures type-only imports do not impact runtime behavior, while utilities like Readonly and Required enforce strict immutability and completeness.

Yes, this approach applies to codebases and teams that want consistent patterns across modules, components, and libraries. Enforcing explicit interfaces and disciplined utility type usage scales safely across different levels of your project architecture.
