There are some important concepts to consider, such as dealing with async behaviours, an area where Redux fails to deliver a solution. redux-observable (because of RxJS) truly shines the most for complex async/side effects. If only there were some way to teach Redux how to deal with functions as actions… Well, this is exactly what redux-thunk does: it is a middleware that looks at every action that passes through the system, and if it's a function, it calls that function. I posted another version a while back with redux and thought it would be helpful to post an updated version showing how it can be done without redux. - Different middleware implementations available for async actions in Redux like redux-thunk, redux-saga, redux-observable etc. 먼저, redux-saga를 살펴보면 Worker + Watcher라는 구조를 가진다.
