`@0y0/use-reducer-x` is an alternative to `React.useReducer` that accepts middlewares to do some cool things before and after dispatch.

Inspired by [Redux Middleware](https://redux.js.org/api/applymiddleware).

### 3-second quick look

```js

import useReducerX from '@0y0/use-reducer-x'

function App() {

  const middlewares = [

    ({ getState, dispatch }) => next => action => {

      // do something before dispatch...

      next(action)

      // do something after dispatch...

    }

  ]

  const [state, dispatch] = useReducerX(reducer, initialState, middlewares)

  // ...

}

```

## Installation

```sh

npm install @0y0/use-reducer-x --save

```

## Real-world Usage

```js

import React from 'react'

import useReducerX from '@0y0/use-reducer-x'

import thunkMiddleware from 'redux-thunk'

function logMiddleware({ getState }) {

  return next => action => {

    console.log('Prev State:', getState())

    console.log('Action:', action)

    next(action)

    console.log('Next State:', getState())

  }

}

function gaMiddleware({ getState }) {

  return next => action => {

    window.ga && window.ga('send', 'event', 'Action', action.type)

    next(action)

  }

}

function useAppReducer(reducer, inititalState) {

  return useReducerX(reducer, inititalState, [

    thunkMiddleware,

    logMiddleware,

    gaMiddleware

  ])

}

function counterReducer(state, action) {

  switch (action.type) {

    case '+1': return { count: state.count + 1 }

    case '-1': return { count: state.count - 1 }

    case '0': return { count: 0 }

    default: return state

  }

}

function resetCounterAfter1Second() {

  return dispatch => setTimeout(() => { dispatch({ type: '0' }) }, 1000)

}

function App() {

  const [state, dispatch] = useAppReducer(counterReducer, 0)

  return (

    

       dispatch({ type: '+1' })}>+

       dispatch(resetCounterAfter1Second())}>Reset

       dispatch({ type: '-1' })}>-

      


      Count: {state.count}

    

  )

}

```
