Necessitates Proper Modularity

    npm package

    A Reactive library for Monkberry applications or any Javascript application, inspired by Flux.

    Why monkberry-flux?

    monkberry-flux is a reactive library that provides for your application multiple stores, wich each store manage your state.

    • Best Performance
    • Reactive Stores
    • Simple and minimalistic API
    • Unidirectional data flow

    Data Flow

    In monkberry-flux data flow is unidirectional, as it should be in Flux:

    • The store dispatch her actions
    • Actions change the state.
    • When state changes you can trigger a handler


    • Application state is held in the store, as a single object.
    • The only way to mutate the state is by dispatching store actions.
    • Actions must be synchronous, and the only side effects they produce should be mutating the state.


    A Store is basically a container that holds your application state. There are two things that makes a monkberry-flux store different:

    • A Store is reactive. Every time the state changes, you can trigger a handler.

    • You cannot directly change the store's state. The only way to change a store's state is by explicitly dispatching store actions.

    Creating a Store is pretty straightforward - just provide an name, state and actions:

    import monkberryFlux from "monkberry-flux";
    const TodoStore = monkberryFlux.createStore({
      name: 'Todo',
      state:  {
        todos: []
      actions: {
        ADD_TASK ( state, task ) {
        REMOVE_TASK ( state, index ) {
          state.todos.splice(index, 1);
    // every time the state changes, this function will be triggered 
    TodoStore.observe( templates => {
      // update each template that are subscribed on the store with
      // the new store state
      templates.forEach( template => template.update(TodoStore.getState());
    module.exports = TodoStore;


    On your template, you can register methods and subscribe your template for when the store state change, your template can update with the new state.

    // templates/main/main.js
    import Template from './main.monk';
    import TodoStore from 'stores/todo';
    export default class extends Template {
        this.on('click', '#change', this.changeName)
        TodoStore.dispatch('name', 'CHANGE_NAME', 'Luis Vincius');


    Application state is held in the store, as a single object. monkberry-flux uses a single state tree - that is, this single object contains all your Store level state and serves as the "single source of truth".

    Store Actions

    Actions are just functions that call the store actions. All actions receive a state as first argument.

    Creating an action inside your Store:

    actions: {
      increment ( state, n ){
        state.count += n

    Calling an action on your component

    import { TodoStore } from './store/todo';
    TodoStore.dispatch('todos', 'ADD_TASK', 10);

    An action receives the state property that you want to change as first argument, the *action event name as the second argument, anything after these are passed as arguments to the action callback.


    To get the store state value, use store.getState() or store.getState( name ), in your Components or Stores.

    API Reference

    • #### Create a Store:

      • monkberryFlux.createStore({ name, state, actions }): Create a single store with the name of Store, State and Actions.
    • #### Store Actions:

      • store.dispatch(stateName, action [,...arguments]): Call a store action.
    • #### Add you store handler to be called when the state changes:

      • store.observe(listeners, stateName, stateValue): Register a handler that will be triggered when any state change in you store.
    • #### Observing the store state changes in your Component or other Store:

      • yourStore.subscribe( listener ): Add the listener for watch the Store state changes.
      • yourStore.unsubscribe( listener ): Remove the listener for unwatch the Store state changes.
