reaction

reaction is a simple state management library that can be used with a React application. This is simply [WIP] or an expriment if you will. You probably should be using redux or a flux implementation like altjs

Installation

    npm install --save reaction-js

storeActions

a store represent a state group within the state tree. These states are modified by actions. Actions are simple functions. Note that action functions needs to have the a specific signature.

    const incrementCount function({}, storeState ) {
        const {count: currentCount} = storeState;
        const count = currentCount + 1;

        return { count }; //new state
    }

stores can be created using the createStore function.

import { createStoreActions } from 'reaction-js';

const add = ( {todo} , {todos = []} ) => {
    //...
};
const delete = ( {id} , {todos = []} ) => {
    //...
};

const update = ( {todo} , {todos = []} ) => {
    //...
};

const storeActions =  createStoreActions( 'todos', add, delete, update );

store

To create the store, you need to pass storeActions.

const store = createStore( [storeActions] );

store.actions.increment();

console.log(store.state);

a store has the following signature

1. store.state

Attribute representing the current state. There is a function named store.getState() that returns the same e.g. store.state and store.getState() points to the same object. Choose your poison.

2. store.actions

Attribute representing all store actions. E.g. if you register increment on the root store, the store.actions.increment is available that can be used by clients to change the state.

3. store.subscribe

Function that can be used to subscribe which is called whenever the state changes.

Testing

npm run test
