Redux Async Action Middleware

This redux middleware enables a dispatching of async actions.

Usage

To use it in your project you have to provide it on your redux middleware stack:

import promiseMiddleware from 'redux-payload-promise';
import { createStore, applyMiddleware } from 'redux';

const store = createStore(
  reducers,
  [ 'some provided state' ],
  applyMiddleware(promiseMiddleware)
);

and define an Action with object defined with a payload key, that refer to your async Promise. For example:

export const loadDataAction = (queryParams) =>
({
  type: LOAD_DATA,
  payload: loadPromise(queryParams),
});

in case of a successful Response it will be dispatched with a JSON object like this:

{
  payload:"[object Promise]"
  result: // your load data query result string
  success:true
}

in nonsuccessful case the success will be false.

You can chain as many dispatches as you want:

dispatch(loadDataAction(queryParams))
        .then((output) => dispatch(filterResonse(JSON.parse(output.result))))
        .then(() => dispatch(sayEverythingIsFine()));
