Bringing class-style reducer factory to your redux stack.

import ReduxClass from '../src/index';
const reducerBundle = ReduxClass.create({
  // Write your logic here
    return state + 1;
    return state - 1;
  add(state, { value }){
    return state + value;
  substract(state, { value }){
    return state - value;
  // Configure the reducer here
    // We return an object where keys are going to be used as action
    return {
      increment: this.increment,
      decrement: this.decrement,
      add: this.add,
    // We bind general action to be handled
    return {
      "substract": this.substract,
    return 0;
let state = reducerBundle.reduce(null, reducerBundle.actions.init()); // state = 0
state = reducerBundle.reduce(state, reducerBundle.actions.increment()); // state = 1
state = reducerBundle.reduce(state, reducerBundle.actions.decrement()); // state = 0
state = reducerBundle.reduce(state, reducerBundle.actions.add({ value: 3 })); // state = 3
state = reducerBundle.reduce(state, { type: "substract", value: 2}); // state = 1


Simply run npm install --save redux-class


Writing reducers can be annoying, it takes time to create actionTypes, and actions, and to put it all into a switch. The imperative style of treating the action using condtionnal is hard to grasp. ReduxClass propose a more declarative way to create your reducers using a class-looking approach. You don't have to take care of the assignation logic, you just describe what action leads to what function.

Pros :

  • Easy to understand even for those who don't know about redux
  • Go straight to your logic without caring about reducer boilerplate (actionCreator, actionTypes..)
  • Functions are reusable, they are just reducer themselves !

Cons :

  • Map one action to one function, but you can call other functions within it
  • A bit less control over your reducer (since the reducer is generated)


ReduxClass.create (config: Object) => { actions: { [key: string]: Function }, reduce: Function }

Create the object holding the reducer.

  • reducer : the function that will handle the reducer logic and return a state given an action
  • actions : actions to dispatch. They are all functions ! There is one function by default, init, which reinitialize the state
createUniqueActions () => { [key: string]: Function }

Return a map whose keys are going to be the actions (you call from yourClass.actions) and whose values are functions to call when we dispatch this action. Those actions are unique, which mean that calling them will only affect the current reducer.

bindActions () => { [key: string]: Function }

Same as createUniqueAction, except the key is a general-purpose key. Those actions are global, so every reducer will respond to them if the action given as key is dispatched.

getInitialState () => mixed

Return the reducer initial state.
