$ npm install react react-redux redux reselect normalizr
$ npm install react-redux-self --save

Why do you need to use react-redux-self, Abilities:

  • Independence of the local component state from the global state directly. You don't need to define one more global reducer, just attach it to component.
  • Independence of the similar components and their state on one page by default works at once relating to `selfID``. (like redux-form)
  • Using a normalizr helps to speed up components update when changing by default, the same concerns manual usage of reselect-factory. Reselect by default isn't convenient and it's often used for the components incorrectly causing uncontrolled memory leaks. This Library provides useful interface (shortcuts) for this operations.
  • Removed opportunity of direct working with mapStateToProps, now it's possible only through selector/getters which speeds up the working and redrawing process. You don't care how many connects you have on the page. It also simplifies logic fragmentation and it's hierarchy
  • Forces to write only the important stuff without all that secondary sh*t in the state in the reducers saving only what can't be calculated. Everything that can be calculated should be calculated in the selector
  • It fix redux state lifecycle. After the component's death it's local reducer also dies (or reducerS, there can be plenty of them and it looks like state mixins of that component, sometimes it's convenient), the component state also dies. There's nothing left and you shouldn't worry about the memory and store size. The only part that stays is what is shown on the page.
  • This approach divides the global reducers with the component reducers and let's think what should be common and what should be local from the beginning.
  • And the most important reason is that you don't use 2 state types - setState and redux-reducers to have all the team operations on the project in the same flow. There will also be an option with setState with the same API for those who want to divide the state from the global store (it will speed up the working process), - in development
  • if there's no need in the local store (reducer) you can do without it. API isn't changed in this case, if the reducer isn't transferred you work directly with the global store and the updates will work out in relation to it with the same API that's there if you're using the local store.

Basic Usage

// /index.js
import { render } from 'react-dom';
import { reducer } from 'react-redux-self';
import { combineReducers, Provider, createStore } from 'react-redux';
import MyComponent from './components/MyComponent';

const store = createStore(combineReducers({
  self: reducer

  <Provider store={store}>
    <MyComponent />

// /components/MyComponent.jsx
import React, { PropTypes } from 'react';

const MyComponent = ({ name, handleChange }) => (
    <h1>Hello! {name}</h1>
    <button type="button" onClick={handleChangeName}>Change My Name To Silvia!</button>

MyComponent.propTypes = {
  name: PropTypes.string.isRequired,
  handleChangeName: PropTypes.func.isRequired

export default MyComponent;

// /components/
import { actionsFactory } from 'react-redux-self';

const action = actionsFactory('MyComponent');

const CHANGE_NAME = action('CHANGE_NAME');

const changeNameAction = (newName) => ({ 
  type: CHANGE_NAME, 
  payload: { name: newName } 

export default (state = { name: 'John', email: '' }, action) => {
  if (action.type === CHANGE_NAME) {
    return {
  return state;

// /components/MyComponent.container.js
import { compose, withHandlers } from 'recompose';
import MyComponent from './MyComponent.jsx';
import { globalStoreConnect } from 'react-redux-self';
import reducer, { changeNameAction } from './'
import { calcGravatarByEmail } from 'lib/gravatar';

export default compose(
    mapDispatchToProps: { changeNameAction },
    getters: [
      (ownStore, globalStore, props) => ownStore 
    selector: (ownStore) => ({
      gravatar: calcGravatarByEmail( // it should be calculated. do not store it OR do not calc it in render function 
    handleChangeName: ({ changeNameAction }) => () => {



Connect is wrapper of "native" react-redux connect.

It provides selector and denormalize helpers to improve development experience.

It provides the component's reducer. It can store data inside and you can use this component several times on the page and this data will not be crossing (there is full isolation between the components).


The same as globalStoreConnect but it use local state storage (emulated "redux on component" approach). Has no connection to redux itself


type String. Default null

Basic selfID of the component. You can change it if you specify the prop selfID deliberately on the component like <MyComponent selfID="some"> it can help you find it to control remotely by action creators.

options.getters[(ownStore, globalStore, ownProps) => ?]

type [Function]. Default null

it is a shortcut for getters of selector. read more about reselect


type Function. Default null.

It is a shortcut for createSelector factory. read more about it here

It receives all arguments as results of getters functions

  getters: [
    (ownStore, globalStore, ownProps) => ownStore 
  selector: (ownStore) => ownStore

options.reducer(state, action)

type Function or [Function]. Default null

It creates it's own store in this component.

if reducer !== null and selector === null and getters === null. Selector and getter will be pointing to it's own store first.

options.denormalize = { propName: scheme }

type Object. Default null

It is a simple shortcut for map denormalization that provides by normalizr. read more about normalizr

const someEntityScheme = new Entity('some');
const someArrayItemScheme = new Entity('someArrayItem');

 denormalie: {
   pathToProp: someEntityScheme,
   pathToAnotherProp: [ someArrayItemScheme ]
options.denoralizeFunction(value, schema, entities)

type Function default denormalize (from configuration)

options.denormalizeEntitiesGetter(ownStore, globalStore, ownProps)

type Function default (_1, { entities }) => entities (from configuration)

options.mapDispatchToProps - (redux connect)

type Object default null

this property only for global connectionType

options.mergeProps - (redux connect)

this property only for global connectionType

options.connectOptions - (redux connect options)

this property only for global connectionType


You can change global settings of this wrapper


Default: (self, storeState) => storeState.entities


Function Default: denormalize

settings.reducerName = null

String Default: 'self'

settings.selfIdByComponentName = null

Boolean Default: 'false'

actionsFactory(ComponentName) => (ActionName) => computed name

  • simple shortcut for using optimizations in self store.

this approach allows to use any action name you want without fear about of aciton-name collisions

import { actionsFactory } from 'react-redux-self';

const action = actionsFactory('MyComponent');

const SOME_ACTION = action('SOME_ACTION');


  • global reducer to connect "self" store into your actual global store
import { reducer as selfReducer } from 'react-redux-self';
import { combineReducers, Provider, createStore } from 'react-redux';

const store = createStore(combineReducers({
  self: selfReducer
