Choosing a TypeScript runtime validation library depends on your performance and bundle size needs. This Skill provides decision trees comparing Zod, TypeBox, and Valibot to help you select the right type safety validator for your project.

The TypeScript satisfies operator and const type parameters enable precise type definitions without widening. This Skill demonstrates advanced type patterns to ensure your objects strictly match interfaces while retaining literal types.

Use TypeScript type aliases for unions and primitives, and interfaces for extensible object shapes. This Skill includes decision trees for choosing between type and interface to optimize your type system configuration.

Optimize your tsconfig.json by configuring project references and strict compilation options. This Skill offers configuration best practices to improve TypeScript build performance and maintainability in monorepos.

TypeScript generic constraint errors often occur when type parameters are too wide. This Skill covers troubleshooting common type inference errors and provides patterns to resolve them using advanced generics.

You can validate API payloads by integrating Zod or Valibot to infer TypeScript types directly from validation schemas. This Skill shows how to ensure runtime data matches your defined types automatically.
