React Adone

Taking the good parts of Redux and React Context to build a flexible, scalable and easy to use state management solution.

Philosophy

Adone is heavily inspired by Redux, the main difference is the lack of reducers. Instead of React Provider and Consumer, we have Container and Subscriber, connected to the same instance of a Store (defined as actions and initial state) and make it's state (or part of it) and the actions bound to the instance available via render-prop API.

Each Subscriber is responsible to get the instantiated Store (creating a new one with initialState if necessary). That makes sharing state across you project extremely easy.

Similar to Redux thunk, actions receive a set of arguments to get and mutate the state. The default setState implementation is similar to React setState, called with an object that will be shallow merged with the current state. But you are free to replace that with something different, even like immer for instance.

Basic usage

npm i react-adone
# or
yarn add react-adone

Creating a Subscriber

import { createStore, createSubscriber } from 'react-adone';

const Store = createStore({
  // value of the store on initialisation
  initialState = {
    count: 0,
  },
  // actions that trigger store mutation
  actions: {
    increment: (by = 1) => ({ setState, getState }) => {
      // mutate state syncronously
      setState({
        count: getState().count + by,
      });
    },
  },
  // optional, mostly used for easy debugging
  name: 'counter',
})

const CounterSubscriber = createSubscriber(Store);

// app.js
import { CounterSubscriber } from './components/counter';

const App = () => (
  <div>
    <h1>My counter</h1>
    <CounterSubscriber>
      {/* Store state is the first argument and actions are the second one */}
      {({ count }, { increment }) => (
        <div>
          {count}
          <button onClick={increment}>+</button>
        </div>
      )}
    </CounterSubscriber>
  </div>
);

Contributing

To test your changes you can run the examples (with npm run start). Also, make sure you run npm run preversion before creating you PR so you will double check that linting, types and tests are fine.

This library merges ideas from redux, react-redux, redux-thunk, react-copy-write, unstated, bey, react-apollo just to name a few. Moreover it has been the result of months of discussions with ferborva, pksjce, TimeRaider, dpisani, JedWatson, and other devs at Atlassian.
