Setup event listeners for various things

Installation

$ npm install redux-effects-events

Usage

Provides access to event listeners on window and document. Right now the library itself decides which events go where, you cannot specify. Currently click and DOMContentLoaded go on document and all others go on window.

Unbinding handlers works similarly to setTimeout/setInterval. Binding a handler will return an id to your composed effect handlers. You can store that id, and then use it to unbind your handler later:

import {handle} from 'redux-effects-events'
import {bind} from 'redux-effects'
import {createAction} from 'redux-actions'

function initialize () {
  return bind(handle('DOMContentLoaded', loadApp), boundLoadedListener)
}

const loadApp = createAction('LOAD_APP')
const boundLoadedListener = createAction('BOUND_LOADED_LISTENER')
const clearLoadedListener = createAction('CLEAR_LOADED_LISTENER')

// ... In your state reducers...

function reduce (state, action) {
  if (action.type === 'BOUND_LOADED_LISTENER') {
    return {...state, loadedListenerId: action.payload}
  } else if (action.type === 'CLEAR_LOADED_LISTENER') {
    return {...state, loadedListenerId: null}
  } else if (action.type === 'LOAD_APP') {
    return {...state, loaded: true}
  }
}

// ... In your main app...

function onStateChange (state) {
  if (state.loaded && state.loadedListenerId) {
    dispatch(clearLoadedListenerId())
  }
}
