atelier-typescript-functional-patterns

Build reliable systems using Algebraic Data Types (ADTs), discriminated unions, Result/Option types, and branded types. These patterns enable the compiler to prove correctness, prevent runtime errors, and make illegal states unrepresentable.

Reliability through types: Use the type system to encode business rules, making invalid states impossible to construct. The compiler becomes your safety net, catching errors at build time rather than runtime.

Copy these into your project to start using functional patterns:

안정적인 TypeScript를 위한 기능적 프로그래밍 패턴입니다. 상태 기계, 구별된 공용체, 결과/옵션 유형, 브랜드 유형을 모델링하거나 유형이 안전한 도메인 모델을 구축할 때 사용합니다. 출처: martinffx/claude-code-atelier.
