react-nipple

A react wrapper for the nipplejs on-screen-joystick.

Resources

Installation

yarn add react-nipple
# or using npm: 
npm install --save react-nipple

Usage

Import and use the component. It supports all options from nipplejs.
It provides callbacks for all supported event types in a camel-cased on-notation, e.g. start -> onStart.

import React from 'react';
import ReactNipple from 'react-nipple';
 
// optional: include the stylesheet somewhere in your app
import 'react-nipple/lib/styles.css';
 
class Example extends React.Component {
    render() {
        return (
            <div>
                <ReactNipple
                    // supports all nipplejs options
                    // see https://github.com/yoannmoinet/nipplejs#options
                    options={{ mode: 'static', position: { top: '50%', left: '50%' } }}
                    // any unknown props will be passed to the container element, e.g. 'title', 'style' etc
                    style={{
                        outline: '1px dashed red',
                        width: 150,
                        height: 150
                        // if you pass position: 'relative', you don't need to import the stylesheet
                    }}
                    // all events supported by nipplejs are available as callbacks
                    // see https://github.com/yoannmoinet/nipplejs#start
                    onMove={(evt, data) => console.log(evt, data)}
                />
            </div>
        );
    }
}

Additional features

  • There is an additional onCreated callback that receives the created nipplejs instance - you might want to use it for direct access to instance methods etc.
  • You can pass the boolean static flag as a prop, which is a shortcut for options={{mode: 'static', position: {top: '50%', let: '50%'}}}

Demo app

The repository is a yarn workspace that contains a small demo app next to the actual react-nipples package.
You can play around with the demo after cloning the repository and installing the dependencies in the root folder.

git clone https://github.com/loopmode/react-nipple.git
cd react-nipple
yarn install
yarn demo

Debug view

There is a debug view based on the official codepen demo.

It supports a data prop that accepts the data object you receive with all nipplejs events, and simply renders its values.
Use it to quickly inspect the values.

import React from 'react';
import ReactNipple from 'react-nipple';
import DebugView from 'react-nipple/lib/DebugView';
 
export default class DebugExample extends React.Component {
    state = {
        data: {}
    };
    render() {
        return (
            <div>
                <ReactNipple
                    options={{ mode: 'static', position: { top: '50%', left: '50%' } }}
                    style={{
                        outline: '1px dashed red',
                        color. 'blue',
                        width: 150,
                        height: 150,
                        position: 'relative'
                    }}
                    onStart={this.handleEvent}
                    onEnd={this.handleEvent}
                    onMove={this.handleEvent}
                    onDir={this.handleEvent}
                    onPlain={this.handleEvent}
                    onShown={this.handleEvent}
                    onHidden={this.handleEvent}
                    onPressure={this.handleEvent}
                />
                <DebugView data={this.state.data} />
            </div>
        );
    }
    handleEvent = (evt, data) => {
        console.log(evt);
        this.setState({ data });
    };
}
