TypeScript FSA Reducers

TypeScript FSA Reducers provides a fluent, typesafe API for defining Redux reducers. It builds on `typescript-fsa` to streamline reducer creation by removing common boilerplate such as `if-else` chains for action type checking and manual extraction of payloads from actions. Instead, it offers a method-chaining approach with dedicated handlers for specific action creators. The current stable version is 1.2.2. While there isn't a strictly defined release cadence, the library has demonstrated consistent updates and a commitment to stability, notably reaching version 1.0.0. Its key differentiators include the fluent builder pattern (`.case()`, `.default()`, `.withHandling()`, `.build()`), strong type inference for state and payloads, and direct integration with `typescript-fsa`'s action creators, making reducer logic concise and highly maintainable in TypeScript Redux applications.
