redux-multi-conditional

Conditionally dispatch multiple actions from one action creator

Installation

$ npm install redux-multi-conditional --save

Usage

Installing the middleware:

1import multiConditionalMiddleware from 'redux-multi-conditional'
2import {createStore, applyMiddleware} from 'redux'
3
4applyMiddleware(multiConditionalMiddleware)(createStore)

Using it:

1import { ConditionalAction } from '../helpers/ConditionalAction.js'
2
3function doSomething () {
4  return [
5    new ConditionalAction((state) => state.isActive, { type: 'WHEN_ACTIVE' }),
6    new ConditionalAction((state,initialState) => state.total != initialState.total, { type: 'TOTAL_CHANGED' }),
7    { type: 'ALWAYS_RUN' }
8  ]
9}

This will enumerate the the actions in order dispatching them when the conditional function returns true.

Thanks

Thanks to the author of Redux itself and the redux-multi middleware which I used as an exemplar for building a Redux middleware package
