react-web-circular-slider

ReactJS component for creating circular slider. This is a rework of the original React-Native project to support ReactJS.

Example app – inspired by Apple's Bedtime ⏰

(It's just an example what you can achieve – with this package you can create any circular slider)

Original React Native Demo

Side By Side with Web Control

(Apologies - the video does not do the original justice - the recording slowed it down due to the gif)

Installation

1. Install library

   npm i --save react-web-circular-slider

Usage

Import Circular Slider

import { CircularSlider } from 'react-web-circular-slider';

Use as follows:

<CircularSlider
  startAngle={startAngle}
  angleLength={angleLength}
  onUpdate={({ startAngle, angleLength }) => this.setState({ startAngle, angleLength })}
  segments={5}
  strokeWidth={40}
  radius={145}
  gradientColorFrom="#ff9800"
  gradientColorTo="#ffcf00"
  showClockFace=True
  clockFaceColor="#9d9d9d"
  bgCircleColor="#171717"
  initialStartTime="18:00"
  initialEndTime="16:00"
  stopIcon={<G><Path .../></G>}
  startIcon={<G><Path .../></G>}
/>

Configuration

You can configure the slider by passing of the following props:

• startAngle – angle where the slider starts (from 0 to 2π)
• angleLength - length of the slider (from 0 to 2π) where data is an object of new values of startAngle and angleLength.
• segments (optional) - SVG doesn't support canonical gradients, so it's imitated by using multiple linear gradients across the slider. In most cases 5 should be fine.
• strokeWidth (optional) - width of slider
• radius (optional) - size of the slider
• gradientColorFrom (optional) - initial gradient color
• gradientColorTo (optional) - final gradient color
• showClockFace (optional) - if component should render clock face
• bgCircleColor (optional) - color of the circle under the slider (pathway for a slider)
• stopIcon (optional) - SVG Path for a stop icon (see the example)
• startIcon (optional) - SVG Path for a start icon (see the example)
• initialStartTime - The initial start time that should be set once the slider is loaded
• initialEndTime - The initial end time that should be set once the slider is loaded

Change events

• onUpdate({ startAngle, angleLength, startTime, endTime, durationMinutes }) - when either start or end slider is moved. onUpdate(data) is triggered, where data is an object of new values of startAngle, angleLength, startTime({h, m}), endTime({h, m}) and duration [int] value expressed in total minutes.
• onStartUpdate({ startAngle, startTime, durationMinutes }) - when the start slider is moved. onStartUpdate(data) is triggered, where data is an object of new values of startAngle, startTime({h, m}) and duration [int] value expressed in total minutes.
• onEndUpdate({ angleLength, endTime, durationMinutes }) - when the end slider is moved. onEndUpdate(data) is triggered, where data is an object of new values of angleLength, endTime({h, m}) and duration [int] value expressed in total minutes.

Working example app

There is an example in the example directory. To get it running, simply run:

npm install
npm start

and you shold be able to access the example on the default localhost:3000
