React-gui-controller NPM

react-gui-controller

Introduction

A graphical user interface for changing states in react. Inspired from Google's popular dat.GUI controller library. This library provides additional functionalities such as Ease curve editor, Draggable placement and Stylable component's. For styling this library uses Zeit styled-jsx.

Installation

npm install react-gui-controller --save

Usage

import React, { Component } from "react";
import Gui, { GuiString, GuiNumber, GuiColor } from "react-gui-controller";
class App extends Component {
   state = {
      data: {
         text: "Some Awesome Val",
         noise: 0.4,
         background: "#dc6900",
         foreground: "#b7c485"
      }
   };

   update = data => {
      this.setState({
         data
      });
   };

   render() {
      const { data } = this.state;
      return (
         <Gui data={data} theme="dark" onUpdate={this.update}>
            <GuiString path="text" label="Head" />
            <GuiNumber path="noise" label="Noise" min={0} max={1} step={0.1} />
            <GuiColor path="background" label="Background" type="hex" />
            <GuiColor path="foreground" label="Foreground" type="hex" />
         </Gui>

data - The data your Gui controller will mutate.
onUpdate - The method which will be called whenever an update is handled by the controller.
