RxJS + ReactJS

The basic implementation of rx-react-store is simple. However, to make the most of it, it's recommended to have basic knowledge on:

Installation 

npm i --save @zazapeta/rx-react-store

Data flow

1. You call store.dispatch(reducer, ...rest)

A reducer is a pure function . It only computes the next state. It should be completely predictable: calling it with the same inputs many times should produce the same outputs. It shouldn't perform any side effects like API calls or router transitions. These should happen before an action is dispatched.

You can call store.dispatch(reducer, ...rest) from anywhere in your app, including components and XHR callbacks, or even at scheduled intervals.

2. The store calls the reducer function you gave it

The store will pass n arguments to the reducer: the first is the current state, rest of arguments are passing with ...rest. For example :

 function setAppCfg(state, title, theme){
  return { ...state, title, theme };
 }

 /*
  dipatch : store.dispatch(setTitle, 'My new title', 'dark')
 */

3. The store save the new state given by reducer

Every connected registered with store.connect()(component) will now be rerender.

Because component.setState is async, the store.dispatch is also async by nature.

Basic starting guide

Store

app.store.js

import RxStore from '@zazapeta/rx-react-store';

let store = new RxStore();

// setup middlewares
store.AfterGlobalParalel.set('InfoLogger', (state, reducer) =>
  console.info(`[${reducer.name}] STATE:`, state),
);

export default store;

Reducers

app.reducers.js

export function setStitle(state, title){
 return {...state, title };
}

Dispatchers

app.dispatchers.js

import appStore from './app.store.js';
import * as appReducers from './app.reducers.js';

export default appStore.createDispatchers(appReducers);

Connected Component (aka Container Component)

App.container.jsx

import appStore from './app.store.js';

function App({title}){
 return (
  <div>
   <h1>{title}</h1>
  </div>
 );
}

export default appStore.connect()(App);

AnOther.jsx

import appDispatchers from './app.dispatchers.js';

export default function InputTitle(){
 return <input type='text' onBlur={(e) => appDispatchers.setTitle(e.target.value)} />
}

Each time the input will be blurred, App.container.jsx will rerender with the new value of the title input. Throttle implemntation is up to you.
