Redux Promise Middleware

Redux promise middleware enables robust handling of async action creators in Redux: it accepts a promise and dispatches pending, fulfilled and rejected actions.

const promiseAction = () => ({
  type: 'PROMISE',
  payload: Promise.resolve(),
})

The middleware can also be combined with Redux Thunk to chain action creators.

const secondAction = (data) => ({
  type: 'TWO',
  payload: data,
})

const first = () => {
  return (dispatch) => {
    const response = dispatch({
      type: 'ONE',
      payload: Promise.resolve(),
    })

    response.then((data) => {
      dispatch(secondAction(data))
    })
  }
}
