Redux User Timing Middleware

redux-user-timing is a Redux middleware designed to integrate Redux action dispatching with the browser's User Timing API, enabling performance profiling of Redux applications within tools like Chrome DevTools. The current stable version is `1.0.2`, released in January 2019. The package has seen no significant updates or active development since then, indicating a maintenance state. Its primary differentiator is its straightforward approach to leveraging a native browser API (`performance.mark()` and `performance.measure()`) for performance measurement, specifically marking Redux action lifecycles. It is explicitly intended for development environments only and does not provide advanced profiling features beyond basic action timing.
