This library provides a declarative approach to conditional logic in TypeScript, replacing imperative branching with structural pattern matching. It functions as a tool for decomposing complex data structures and mapping them to specific execution branches, ensuring that all possible states are accounted for during development.
The library distinguishes itself by enforcing exhaustive logic, which requires developers to address every possible branch of a data structure to prevent runtime errors. By leveraging compile-time type narrowing and recursive evaluation, it allows for the validation and transformation of deeply nested objects while maintaining strict type safety throughout the control flow.
Beyond its core matching capabilities, the library supports complex data validation and functional state transformation. It provides a framework for evaluating incoming data against defined structural requirements, ensuring that variations in input are processed in a predictable and type-safe manner.
