DEPRECATED

ES6 arrow functions with implicit returns, argument destructuring and object literal enhancements make it easy to keep your action creators compact without helper functions.

ES6 Alternative

import types from './action-types'

export let addLesson = () => ({type: types.ADD_LESSON})

export let importLessons = (lessons) => ({type: types.IMPORT_LESSON, lessons})

export let updateLesson = ({id, update}) => ({type: types.UPDATE_LESSON, id, update})

Redux Action Utils

Factory functions for reducing action creator boilerplate.

npm install --save redux-action-utils

Before

var types = require('./action-types')

function addLesson() {
  return {
    type: types.ADD_LESSON
  }
}

function importLessons(lessons) {
  return {
    type: types.IMPORT_LESSONS,
    lessons
  }
}

function updateLesson(options) {
  return {
    type: types.SELECT_LESSON,
    id: options.id,
    update: options.update
  }
}

module.exports = {addLesson, importLessons, updateLesson}

After

var types = require('./action-types')
var {actionCreator, optionsActionCreator} = require('redux-action-utils')

module.exports = {
  addLesson: actionCreator(types.ADD_LESSON),
  importLessons: actionCreator(types.IMPORT_LESSONS, 'lessons'),
  updateLesson: optionsActionCreator(types.UPDATE_LESSON, 'id', 'update')
}
