redux-ondispatch v1.0.0

redux-ondispatch

redux-ondispatch is middleware that allows you to include a function to be executed when a redux action is dispatched. Eg:

function myAjaxAction(id) {
  return {
    type: FETCH_SOMETHING,
    payload: { id },
    onDispatch: (store, action) => {
      fetch(`/api/something/${action.payload.id}`)
      .then((something) => {
        store.dispatch({
          type: SOMETHING_FETCHED,
          something
        });
      });
    }
  };
}

store.dispatch(myAjaxAction(1));

Usage

0) Requirements: redux

1) Install the package via npm or yarn

> npm install redux-ondispatch

or

> yarn add redux-ondispatch

2) Define the middleware as part of your redux store

import { createStore, applyMiddleware } from 'redux';
import reducers from './reducers'; // Or wherever
import reduxOnDispatch from 'redux-ondispatch';

const store = createStore(reducers, applyMiddleware(
                                      reduxOnDispatch,
                                      // any other middleware
                                    ));

That's it! Any action dispatched with a function assigned to a top-level onDispatch attribute will be executed when the action is dispatched.
