redux-middleware-oneshot

Create Redux actions from arbitraty sources out of middlewares.

Installation

npm install --save redux-middleware-oneshot

Usage

// In this example, we want to create someAction in redux for every
// change-event emitted by someEventEmitter
import someEventEmitter from './someEventEmitter';
import someAction from './someAction';

// And for this we simply create a new oneShot middleware
import createOneShot from 'redux-middleware-oneshot';
const myMiddleware = createOneShot((dispatch) => {
    // This function is called exactly once as soon as the first action
    // runs through redux. Perfect moment to glue things together!
    someEventEmitter.addEventListener('change', (event) => {
        dispatch(someAction(event.value));
    });
});

// Everything else is straight forward Redux ...
import { createStore, applyMiddleware, combineReducers } from 'redux';
const createStoreWithMiddleware = applyMiddleware(myMiddleware)(createStore);
const store = createStoreWithMiddleware(/* reducer */);
