I want to get the current action from store.

[whatifif]

store has "subscribe" method to notify "the change of state" to all the subscribing clients.

It will be convenient if the current action is able to be sent to the clients in 'subscribe' method.

Current state can be obtained from store.getState().
But there is no such method to get the current action from store
( for example, store.getAction() which will return the current action dispatched to the store )

Any idea is appreciated.

Please see #1057, this is the same request.

Also #1091, #622.

I found an exact solution to this issue. So I leave the link below.
This has an advantage: Action can be controlled before it is dispatched to the store.
