redux-reset-state

A redux plugin to reset the redux state you specify.

$ npm install -S redux-reset-state

Usage

import { createStore, applyMiddleware } from 'redux'
import rootReducer from 'your/path/reducers'
import { composeRootReducer, resetMiddleware, resetReduxState } from 'redux-reset-state'

// Some code is omitted here

const store = createStore(composeRootReducer(rootReducer), initialState, applyMiddleware(
  resetMiddleware
))

// If the shape of your application state is like this: { state: { key: { "state-key": 'value' } } }, 
// you can exec the following line of code to reset the state: 
resetReduxState([['state', 'key', 'state-key'], ['state', 'key']])

Hoc in React application

Now the resetStateWhenUnmount has been remove from the package, you can copy the code bellow to your application, the hoc will use the stateKeys to reset the corresponding states of your application, and in React 16.3, you can use React.forwardRef to reconstruct it

import React, { Component } from 'react'
import { resetReduxState } from 'redux-reset-state'

export default function (stateKeys) {

  return function wrapWithRedsetStateWhenUnmount(WrappedComponent) {
    class RedsetStateWhenUnmount extends Component {
      static displayName = `Reset(${JSON.stringify(stateKeys)})(${WrappedComponent.displayName || WrappedComponent.name || 'Component'})`
      
      componentWillUnmount() {
        resetReduxState(stateKeys)
      }
      
      render() {
        return <WrappedComponent resetReduxState={resetReduxState} {...this.props} />;
      }
    }

    return RedsetStateWhenUnmount;
  }
}
