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 的函数式编程模式。在对状态机、可区分联合、结果/选项类型、品牌类型或构建类型安全域模型进行建模时使用。 来源：martinffx/claude-code-atelier。
