react-scratchcard-v2

react-scratchcard-v2

A scratchcard component for React

Note

This is a clone of https://github.com/aleksik/react-scratchcard

Improvement:

• Resize the image using width and height props (in the original repo, the image was croped)
• Smooth fade out animation on scratch complete
• Add type definition (ts)
• Change brush size through props
• Use custom brush through props
• Define a custom check zone through props

Demo

Install

npm install --save react-scratchcard-v2

or

yarn add react-scratchcard-v2

import React from 'react';

      <ScratchCard
        width={320}
        height={226}
        image={IMG}
        finishPercent={80}
        onComplete={() => console.log('complete')}
      >
        <div style={{
          display: 'flex',
          width: '100%',
          height: '100%',
          alignItems: 'center',
          justifyContent: 'center'

        height={226}
        image={IMG}
        finishPercent={80}
        customBrush={{
          image: require('./brush.img'),
          width: 15,
          height: 15
        }}
      >
        <h1>Scratch card</h1>
