What problem does it solve?
This Skill helps TypeScript developers perform pattern matching, exhaustive union handling, and runtime validation efficiently, reducing boilerplate and errors.
Core Features & Use Cases
- Pattern Matching: Provides APIs like
match, match.promise, and matchBy to handle complex conditional logic based on object structure, discriminated unions, and paths.
- Type Safety & Exhaustiveness: Ensures comprehensive coverage with
exhaustive() checks, preventing unhandled cases in TypeScript projects.
- Runtime Validation: Offers guards like
isMatching and assertMatching to validate data objects at runtime, throwing detailed errors when mismatched.
- Use Case: Developers can parse API responses, configuration objects, or state machines with concise, type-safe code, and catch errors early during development.
Quick Start
Use the ts-match library to handle pattern matching for API response parsing or discriminated union handling in TypeScript.
