Redux Blue Shell

Redux Blue Shell is a simple way to build apps using React and Redux, inspired by Hyperapp, Elm and Rematch.

Install

The following does not work, but might someday

npm install redux-blue-shell react react-dom --save

Getting started

In Redux Blue Shell you organize your state into models where you also put the actions and effects that can access and transform this state.

But first we need to grab some dependencies

import React from "react";
import ReactDOM from "react-dom";
import { init } from "redux-blue-shell";

Now lets define our model. It's going to be a simple counter app.

const model = {
  state: {
    count: 0
  },
  actions: {
    up: state => (n = 1) => ({ count: state.count + n }),
    down: state => (n = 1) => ({ count: state.count - n })
  },
  effects: {
    upDelayed: actions => () => setTimeout(actions.up, 1000)
  }
};

Next we'll define our top-level react component. Blue Shell will induce the models state, actions and effects as props into this component.

const View = ({ state, actions, effects }) => (
  <div>
    <h1>{state.count}</h1>
    <button onClick={() => actions.down()}>down</button>
    <button onClick={() => actions.up()}>up</button>
    <button onClick={() => actions.up(10)}>up more</button>
    <button onClick={effects.upDelayed}>up later</button>
  </div>
);

Lastly we init Blue Shell with our model and view. Then we render the app.

const App = init(model, View);
ReactDOM.render(<App />, document.getElementById("root"));

Et voila, our first Blue Shell app is complete

Nesting Models

You can nest models to help structure your app in ways you see fit.

const model = {
  authentication: autheticationModel,
  feature1: feature1Model,
  bigFeature2: {
    feature2a: feature2aModel,
    feature2b: feature2bModel
  }
};

Roadmap

• add more tests
• add a connect function
• add possibility to subscribe to actions in different models
• look into support for Preact
• create a documentation / page
