Redux effects driver for localStorage

Installation

$ npm install redux-effects-localstorage

Usage

Simple redux-effects driver for localStorage. Add it to your redux middleware stack like this:

import localStorage from 'redux-effects-localstorage'

applyMiddleware(localStorage(window.localStorage))(store)

And then dispatch it actions, like this:

store.dispatch({
  type: 'EFFECT_LOCALSTORAGE',
  payload: {
    type: 'setItem',
    key: 'todos.0',
    value: 'Clean the kitchen'
  }
})

Or, use the action creators that come bundled with it:

import localStorage from 'redux-effects-localStorage'

store.dispatch(localStorage.setItem('todos.0', 'Clean the kitchen'))

The API of the action creators is identical to that of the native localStorage object, with the sole exception that the property length has been changed to the function getLength.

Example - Auth token getter/setter

Getting/setting an auth token:

function authToken (newToken) {
  return arguments.length > 0 
    ? localStorage.setItem('authToken', newToken)
    : localStorage.getItem('authToken')
}

function setUserToken (token) {
  return {type: 'SET_USER_TOKEN', payload: token}
}

function reducer (state, action) {
  if (action.type === 'SET_USER_TOKEN') {
    return {
      ...state,
      authToken: action.payload
    }
  }
}

function checkUserStatus () {
  store
   .dispatch(authToken())
   .then(token => store.dispatch(setUserToken(token))
}

Use with sessionStorage

Each of the action creators takes another parameter, STORAGE_TYPE. You can access this from STORAGE_TYPE exported by this module. Values are local (the default) and session, which you can use if you want the actions to be applied to session storage rather than local storage.
