Creates an effect that instructs the middleware to queue the actions matching
pattern using an event channel. Optionally, you can provide a buffer to
control buffering of the queued actions.
Example
The following code creates a channel to buffer all USER_REQUEST actions.
Note that even the Saga may be blocked on the call effect. All actions that
come while it's blocked are automatically buffered. This causes the Saga to
execute the API calls one at a time
import { actionChannel, call } from 'redux-saga/effects'
import api from '...'
