Pass custom store enhancer and middleware to redux store

[thangngoc89]

Some basic function that I could build when statinamic have this feature:

• Search : https://github.com/treasure-data/redux-search

I could send a PR for this. But I'm waiting for #91

Two things:

• I was thinking about removing redux because I am not sure it's really useful Consider replacing redux in favor of react context #40, feel free to give your thoughts about this
• if we keep it, have you any idea about a nice flexible way to allow that?

Allow 2 extra args in createStore function:

A proof of concept

// https://github.com/MoOx/statinamic/blob/master/src/redux/createStore/index.js#L4
import { createStore, applyMiddleware, compose } from "redux"
import thunk from "redux-thunk"

export default function(reducer = {}, initialState = {}, extraMiddlewares = {}, storeEnhancers = {}) {
  function promiseMiddleware() {
    return (next) => (action) => {
      const { promise, types, ...rest } = action
      if (!promise) {
        return next(action)
      }
      else if (!promise.then) {
        throw new Error(
          "promiseMiddleware expects a promise object that implements then()"
        )
      }

      const [ REQUEST, SUCCESS, FAILURE ] = types
      next({ ...rest, type: REQUEST })
      return promise.then(
        (response) => next({ ...rest, response, type: SUCCESS }),
        (error) => next({ ...rest, error, type: FAILURE })
      )
    }
  }

  let finalCreateStore

  if (__DEVTOOLS__) {
    const { devTools, persistState } = require("redux-devtools")

    finalCreateStore = compose(
      applyMiddleware(promiseMiddleware, thunk, ...extraMiddlewares),
      devTools(),
      persistState(window.location.href.match(/[?&]debug_session=([^&]+)\b/)),
      ...storeEnhancers
    )(createStore)
  }
  else {
    finalCreateStore = applyMiddleware(promiseMiddleware, thunk)(createStore)
  }

  return finalCreateStore(reducer, initialState)
}

```js

Well, why not.
