]

export default () => (
  <>
    <Wheel
      mustStartSpinning={mustSpin}
      prizeNumber={3}
      data={data}
      backgroundColors={['#3e3e3e', '#df3428']}
      textColors={['#ffffff']}
    />
  </>

Types

WheelData

interface WheelData {
  option?: string;
  image?: ImageProps;
  style?: StyleType; // Optional
  optionSize?: number; // Optional
}
Prop Type Default Description
option string '' String to be rendered inside an option.
image ImageProps - Image to be rendered inside an option. It is configured through ImageProps
style StyleType - Styles for option. It is configured through StyleType
optionSize number 1 Integer that sets the size of the option measured in roulette pieces. For example: if data provides 2 options A and B, and you set A's optionSize to 2, B's optionSize to 1, the roulette will render 3 pieces: 2 corresponding to A and 1 corresponding to B. Therefore, A will appear to be twice as big as B.

StyleType

interface StyleType {
  backgroundColor?: string; // Optional
  textColor?: string; // Optional
  fontFamily?: string; // Optional
  fontSize?: number; // Optional
  fontWeight?: number | string; // Optional

}
Prop Type Default Description
uri string - Image source. It can be url or path.
offsetX number 0 Image offset in its X axis
offsetY number 0 Image offset in its Y axis
sizeMultiplier number 1 A value of 1 means image height is calculated as 200px * sizeMultiplier and width will be calculated to keep aspect ratio.
landscape boolean false If true, image will be rotated 90 degrees so as to render in a landscape orientation.

Example (using useState)

import React, { useState } from 'react'
import { Wheel } from 'react-custom-roulette'

const data = [
  { option: '0' },
  { option: '1' },
  { option: '2' },
]

export default () => {
  const [mustSpin, setMustSpin] = useState(false);
  const [prizeNumber, setPrizeNumber] = useState(0);

  const handleSpinClick = () => {
    if (!mustSpin) {
      const newPrizeNumber = Math.floor(Math.random() * data.length);
      setPrizeNumber(newPrizeNumber);
      setMustSpin(true);
    }
  }

  return (
    <>
      <Wheel
        mustStartSpinning={mustSpin}
        prizeNumber={prizeNumber}
        data={data}

        onStopSpinning={() => {
          setMustSpin(false);
        }}
