ext-react

Extension React is a library that build on top of React, helping you build data-intensive, cross-platform web apps for desktops, tablets, and smartphones.

Quick Start

Use npm or yarn to install following dependencies:

  • babel-polyfill
  • babel-preset-env
  • babel-preset-react
  • d3
  • react
  • react-dom
  • rxjs
  • ext-react

To launch your app, add the following to your app.js file

// ./app.js
import 'babel-polyfill';
import React, { PureComponent } from 'react';
import { Application } from 'ext-react';
import Viewport from './components/viewport/viewport';
 
@Application()
export default class App extends PureComponent {
  render() {
    return <Viewport />
  }
}

Core Concepts

Full documentation: https://huytrongnguyen.github.io/extension-react

Components

A component in Extension React is the combination of a React Component and a component class that controls a portion of the screen. Here is an example of a component that display a simple string:

import React, { PureComponent } from 'react';
import { Component } from 'ext-react';
 
class DashboardView extends PureComponent {
  render() {
    return <h1>{this.props.$view.title}</h1>;
  }
}
 
@Component({
  view: DashboardView
})
export default class Dashboard {
  constructor() {
    this.title = 'Dashboard';
  }
}

Every component begins with an @Component decorator function that takes a metadata object. The metadata object describes how the React Component and component class work together. That's mean you can access any property or method of component class via this.props.$view.

Actually, with the above example, it can be implemented like this:

import { Component } from 'ext-react';
 
@Component({
  view: ({ $view }) => <h1>{$view.title}</h1>
})
export default class Dashboard {
  constructor() {
    this.title = 'Dashboard';
  }
}

Data Package

Stores load data via a Proxy. Creating a Store is easy - we just tell it the Proxy to use for loading and saving its data:

import { Store } from 'ext-react';
 
export default Store({
  storeId: 'UserStore',
  proxy: {
    url: '/api/user/search'
  }
});

In the example above we configured an AJAX proxy to load data from the url /api/user/search.

Now, just bind a store to the Component:

import React, { PureComponent } from 'react';
import CardStore from '~/stores/card';
 
export default class Card extends PureComponent {
  constructor(props) {
    super(props);
    this.reload = () => this.forceUpdate();
  }
 
  componentDidMount() {
    CardStore.clearData();
    CardStore.load();
    CardStore.subscribe(this.reload);
  }
 
  render() {
    const records = CardStore.getData();
    return <section>
      <section className="rx-grid-header">
        <div className="d-flex flex-row rx-grid-header-container">
          <div className="rx-grid-column-header text-sm-center" style={{width:'20%'}}>ID</div>
          <div className="rx-grid-column-header text-sm-center" style={{width:'20%'}}>Name</div>
          <div className="rx-grid-column-header text-sm-center" style={{width:'20%'}}>Type</div>
          <div className="rx-grid-column-header text-sm-center" style={{width:'20%'}}>Armor</div>
          <div className="rx-grid-column-header text-sm-center" style={{width:'20%'}}>Weapon</div>
        </div>
      </section>
      <section className="rx-grid-body" style={{overflow:'visible'}}>
        <section className="rx-grid-view">
          {records.map(record => <article className="d-flex flex-row rx-grid-row">
            <div className="rx-grid-cell" style={{width:'20%'}}>{record.get('Id')}</div>
            <div className="rx-grid-cell" style={{width:'20%'}}>{record.get('Name')}</div>
            <div className="rx-grid-cell" style={{width:'20%'}}>{record.get('Type')}</div>
            <div className="rx-grid-cell" style={{width:'20%'}}>{record.get('ArmorUsable')}</div>
            <div className="rx-grid-cell" style={{width:'20%'}}>{record.get('WeaponUsable')}</div>
          </article>)}
        </section>
      </section>
    </section>;
  }
}

In this above example, we use subscribe to update the component whenever data's changed. Because Store convert data to Model then you need to use get to access data.

Screen Navigation

Route decorator is most basic responsibility is to render UI when a location matches the route’s path.

Link provides declarative, accessible navigation around your application.

HashRouter uses the hash portion of the URL (i.e. window.location.hash) to keep your UI in sync with the URL.

// ./app.js
import 'babel-polyfill';
import React, { PureComponent } from 'react';
import { Application } from 'ext-react';
import Viewport from './components/viewport/viewport';
 
@Application({
  views: [
    require('./components/search'),
    require('./components/details'),
    require('./components/notfound'),
  ],
})
export default class App extends PureComponent {
  render() {
    return <Viewport />
  }
}
 
// ./components/viewport/viewport.js
import React, { Component } from 'react';
import { Link, HashRouter } from 'ext-react';
 
export default class Viewport extends Component {
  render() {
    return <section>
      <Link to="/">Dashboard</Link>
      <Link to="/search">Search</Link>
      <Link to="/details/huynguyen">Details</Link>
      <HashRouter />
    </section>;
  }
}
 
// ./components/search/search.js
import React from 'react';
import { Route, Component } from 'ext-react';
 
@Route('/search')
@Component({
  view: () => <section />
})
export default class Search { }
 
// /components/search/detail.js
import React from 'react';
import { Route, Component } from 'ext-react';
 
@Route('/details/:name')
@Component({
  view: ({ params }) => <h1>{params.name}</h1>
})
export default class Details { }
 
// ./components/notfound/notfound.js
import React, { PureComponent } from 'react';
import { Route } from 'ext-react';
 
@Route('*')
export default class NotFound extends PureComponent {
  render() {
    return <h1>'{this.props.params.route}' doesn't exist</h1>
  }
}

Built-in Components

Extension React has several build-in components to support for building responsive web. For example:

  • Grid are an excellent way of showing large amounts of tabular data on the client side. Essentially a supercharged , Grid iss an incredibly versatile component that provides an easy way to display and edit data.
// ./app.js
import 'babel-polyfill';
import React, { PureComponent } from 'react';
import { Application } from 'ext-react';
 
@Application({
  stores: [
    require('./stores/cards'),
  ],
  views: [
    require('./components/viewport/viewport'),
    require('./components/cards'),
  ],
})
export default class App extends PureComponent {
  render() {
    return <Viewport />
  }
}
 
// ./stores/card
import { Store } from 'ext-react';
 
export default Store({
  storeId: 'CardStore',
  fields: [ 'Name' ],
  proxy: {
    url: '/data/card.json'
  }
})
 
// ./components/cards.js
import { Route, Component } from 'ext-react';
 
@Route('/example/cards')
@Component({
  stores: [ 'CardStore' ],
  view: CardView
})
export default class Card {
  @bind
  saveChanges() {
    this.stores.CardStore.sync({
      fail: err => console.log(err)
    });
  }
 
  @bind
  rejectChanges() {
    this.stores.CardStore.rejectChanges();
  }
}
 
// ./components/cards.view.jsx
import React, { PureComponent } from 'react';
import { Grid } from 'ext-react';
 
export default class CardView extends PureComponent {
  componentDidMount() {
    this.props.stores.CardStore.load();
  }
  render() {
    const {CardStore } = this.props.stores;
    return <Grid store={CardStore}>
      <div header="Id" dataIndex="Id" />
      <div header="Name" dataIndex="Name" editable />
      <div header="Type" dataIndex="Type" />
    </Grid>
  }
}
