redux-promise-middleware

Transforms a single async action into separate pending, fulfilled, and rejected actions based on promise lifecycle, eliminating boilerplate code for tracking async states as highlighted in the README.

Works alongside other middleware like Redux Thunk, enabling complex async workflows such as chaining actions, demonstrated in the README example with firstAction and secondAction.

Requires only a promise as the action payload to trigger the middleware, making setup straightforward and reducing initial overhead.

Automatically dispatches rejected actions on promise failure, centralizing error state management in the Redux store without manual intervention.
