Side Effects

For comparisons between side effect approaches, see What is the right way to do asynchronous operations in Redux?.

Widely Used Tools

• redux-thunk
  https://github.com/gaearon/redux-thunk
  The simplest possible side effects approach: dispatch functions instead of objects, which then get access to dispatch and getState. (Variations on the concept listed on the Middleware page.)

• redux-saga
  https://github.com/redux-saga/redux-saga
  Generator-based side effects approach. Create "sagas", which act like background threads or daemons that can listen for actions and dispatch objects describing side effects.

• redux-loop
  https://github.com/raisemarketplace/redux-loop
  Sequence your effects naturally and purely by returning them from your reducers. Also returns descriptive objects, which are executed later.

• redux-observable
  https://github.com/redux-observable/redux-observable
  RxJS 5-based middleware for Redux. Compose and cancel async actions and more.

• redux-logic
  https://github.com/jeffbski/redux-logic
  Redux middleware for organizing business logic and action side effects.
