We saw that
take Effects are resolved by waiting for actions to be dispatched to the Store. And that
put Effects are resolved by dispatching the actions provided as argument.
When a Saga is started (either at startup or later dynamically), the middleware automatically connects its
put to the store. The 2 Effects can be seen as a sort of Input/Output to the Saga.
redux-saga provides a way to run a Saga outside of the Redux middleware environment and connect it to a custom Input/Output.
