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:

可靠 TypeScript 的函數式程式設計模式。在對狀態機、可區分聯合、結果/選項類型、品牌類型或建構類型安全性域模型進行建模時使用。 來源：martinffx/claude-code-atelier。
