typescript

Enforce strict TypeScript patterns by replacing any with unknown, deriving union types from const objects, and keeping interfaces flat. This improves type safety, readability, and maintainability across frontend and backend codebases.

Derive TypeScript types from a const object using the const type assertion pattern. This creates a union type from the object's literal values, ensuring runtime values and type definitions stay synchronized and safe.

Use unknown instead of any in TypeScript generics to enforce type safety without sacrificing flexibility. The unknown type forces explicit type checking before usage, while generics preserve type relationships throughout your codebase.

Yes, this TypeScript pattern approach works for both frontend and backend codebases. It enforces consistency across teams and modules by applying flat interface design and safe generic usage regardless of the runtime environment.

Create flat interfaces in TypeScript by limiting interface depth to one level. This pattern improves maintainability and refactorability by preventing deeply nested type structures that complicate module updates and team collaboration.

Avoid generic types in TypeScript when a simpler interface or type alias fully covers the use case. Overusing generics can reduce readability and maintainability, favor flat interfaces and const-based derivations for straightforward type structures.
