import * as React from 'react';
import ReactHardware, { Led } from 'react-hardware';

class FlashingLed extends React.Component {
  state = {value: 1};

  componentDidMount() {
    setInterval(() => {
      this.setState({
        value: this.state.value === 0 ? 1 : 0,
      });
    }, 500);
  }

  render() {
    return <Led pin={8} value={this.state.value} mode={'OUTPUT'} />;

Pragma

Custom Render

Demo

A custom Filesystem Renderer

Atomic Entities

Folder

File

<folder name="Foo">
    <folder name="Bar">
        <file name="HelloWorld" extension=".txt">
            Hello CodeBuds
        </file>
    </folder>
</folder>

But that's not where this ends
