I am currently learning both libraries. What are the criteria for choosing which one ist best for my type of application? Redux-thunk has three times more weekly Npm downloads right now. Is there any other big player I should know about?
The Redux Style Guide recommends thunks for most use cases
The reasoning behind it is simple: Thunks are very easy to use and most of the time "just enough". At the same time, is is also recommended to use the official Redux Toolkit (which you best learn by following the official Redux Tutorial) and recently, Redux Toolkit is also shipping with an api caching solution called RTK-Query which - if you only need to handle api communication - might remove your need for hand-written sagas or thunks altogether.
