Reduce boilerplate in Redux

Reduce boilerplate in Redux

• Create actions similar to Flummox.
• Generate action ids.
• Supports actions with promises, and therefore ES7 async.

actions.js

//
// 4 different ways to write actions: ES7 Async/Await, Promises, Async Function, Synchronous.
//

import {createActions} from './helpers.js'

export const CounterActions = createActions({

  async incrementAsync() {

    const promise = new Promise((resolve, reject) => {
      setTimeout(() => {
        resolve()
      }, 1000)
    })

    let result = await promise
    return result

  },

  incrementPromise() {
  
    // Debug
    const promise = new Promise( (resolve, reject) => {
      setTimeout(() => {
        resolve()
      }, 1000)
    })
  
    return {
      types: ['INCREMENT_BEGIN', 'INCREMENT_SUCCESS', 'INCREMENT_FAILURE'],
      promise,
    }
  
  },

  incrementFunctionWithState() {
    return (dispatch, getState) => {
      const {counter} = getState()
      console.log(dispatch)
      if (counter % 2 === 0) return
      dispatch(CounterActions.increment())
    }
  },

  incrementFunction()) {
    return dispatch => {
      setTimeout(() => {
        dispatch(CounterActions.increment())
      }, 1000)
    }
  },

  increment() {
    return {}
  },

})
