``js
import { createAction, createReducer } from 'redux-action'
`

* Uses dispatch with Promise chain
* Generates action type automatically when no pass action type
* payload first reducer
* Assign updated data to state automatically
* Works with redux-thunk

$3

* createAction

`js
import { createAction } from 'redux-action'

const action = createAction('action', (...args) => {
// ...
return payload
})

const asyncAction = createAction('async action', (...args) => {
// ...
return Promise.resolve(payload)
})
`

* createReducer

`js
import { createReducer } from 'redux-action'

const reducer = createReducer(defaultState, {
'action': (payload, state, action) => {
// ...
// only return updated state
// will assign to state automatically
return updatedData
},

'async action': (payload, state, action) => {
// ...
return updatedData
},

'common usage': payload => ({some: payload}),
})
`

* Uses dispatch with Promise

`js
class App extends React.Component {
async updateData(data) {
const {
dispatch,
userId
} = this.props

await dispatch(updateUserInfo(userId, data))
await dispatch(getUserInfo(userId))
// ...
}

render() {
// ...
}
}
`

$3

* store.js

`js

import { createStore, applyMiddleware } from 'redux'
import reduxThunk from 'redux-thunk'
import reducer from './reducer'

const createStoreWithMiddleware = applyMiddleware(
reduxThunk
)(createStore)

const store = createStoreWithMiddleware(reducer)

export default store

`

* action.js

`js

import { createAction } from 'redux-action'

export const setUserStatus = createAction('set user status', status => status)
export const getUserInfo = createAction('get user info', () => Promise.resolve(userInfo))
`

* reducer.js

`js

import { createReducer } from 'redux-action'
import { combineReducers } from 'redux'

const defaultState = {
status: 'normal',
info: {},
}

const user = createReducer(defaultState, {
'set user status': status => ({status}),
'get user info': info => ({info}),
})

// combine reducers

const rootReducer = combineReducers({
user,
})

export default rootReducer
`

$3

createAction also can generate a unique type, when no pass any string in the first argument.

* action.js

`js

import { createAction } from 'redux-action'

export const setUserStatus = createAction(status => status)
export const getUserInfo = createAction(() => Promise.resolve(userInfo))
`

* reducer.js

`js

import { createReducer } from 'redux-action'

import {
setUserStatus,
getUserInfo
} from './action'

const defaultState = {
status: 'normal',
info: {},
}

const user = createReducer(defaultState, {
[setUserStatus]: status => ({status}),
[getUserInfo]: info => ({info}),
})
