redux-hook-middleware

A Redux middleware to provide easy hooks on pre/post dispatch.

install

$ npm i redux-hook-middleware -S

usage

import { createStore, applyMiddleware } from 'redux'
import hookMiddleware, { registerPrehook } from 'redux-hook-middleware'

// redux setup
const initialState = { /* initial state */ }
const reducer = (state = initialState, action) => { /* reducer function logics */ return state }
const middlewares = [hookMiddleware]
const store = createStore(reducer, initialState, applyMiddleware(...middlewares))

// middleware logic
registerPrehook('HOOKING_ACTION_TYPE', (store, action) => {
  console.log('prehooked!')
  // do anything inside callback
  // you can also dispatch other actions
  store.dispatch({ type: 'SOME_ACTION_TYPE' })
})

// how does it works
store.dispatch({ type: 'HOOKING_ACTION_TYPE' }) // 'prehooked!'
