Typesafe utilities for "action-creators" in Redux / Flux Architecture
...It provides strongly typed helpers for creating synchronous and asynchronous Redux actions. Its reducer utilities infer state and action types while validating handlers at compile time. Helper types can derive action and state types directly from existing implementations. The library supports integrations with common asynchronous approaches such as redux-observable and redux-saga. It is distributed in CommonJS, ES module, and UMD formats and includes runtime tests, type tests, and performance benchmarks intended to preserve type safety and efficiency.
