I realize this is a basic question but I had no luck finding the answer elsewhere.

Is store.dispatch synchronous or asynchronous in Redux ?

In case it is asynchronous is there a possibility to add a callback after the action has been propagated as it is possible with React ?

AFAIK, dispatching action is synchronous. In case if you are willing to address the asynchronous call, you can use the thunk-middleware in redux, where dispatch is provided as a callback function which you can invoke as per your convenience.
