Introduction

Taking screenshots of web pages or specific DOM elements is essential for tasks like debugging, documentation, or capturing user-specific data in web applications. In React, various libraries such as dom-to-image, html2canvas, and rasterizeHTML.js simplify this process, while native JavaScript offers a library-free solution. In this blog, we will guide you through these methods, helping you choose the best one for your needs. At SvayambhuTech, recognized as a top website developer in Mumbai, we pride ourselves on leveraging the latest technology to enhance web development and application efficiency.

Using dom-to-image

dom-to-image converts DOM nodes into images using SVG and a canvas. To implement it:

  1. Install the Library
npm install dom-to-image

2. Create a Screenshot Function

import domtoimage from 'dom-to-image';

const takeScreenshot = () => {
    const node = document.getElementById('capture');
    domtoimage.toPng(node)
        .then(dataUrl => {
            var img = new Image();
            img.src = dataUrl;
            document.body.appendChild(img);
        })
        .catch(error => {
            console.error('Oops, something went wrong!', error);
        });
};

3. Trigger the Function

<div id="capture">Hello, SvayambhuTech!</div>
<button onClick={takeScreenshot}>Take Screenshot</button>

Using html2canvas

html2canvas captures screenshots by rendering the HTML into a canvas.

  1. Install the Library
npm install html2canvas

2. Screenshot Function

    import html2canvas from 'html2canvas'; 

const captureScreen = () => { html2canvas(document.getElementById('capture')).then(canvas => { document.body.appendChild(canvas); }); };

    3. Integrate with UI

      <button onClick={captureScreen}>Capture</button>

      Using rasterizeHTML.js

      For complete HTML rendering, including CSS and SVG:

      1. Install the Library
      npm install rasterizehtml

      2. Rendering Function

      import rasterizeHTML from 'rasterizehtml';

const renderToCanvas = () => {
    const canvas = document.getElementById('myCanvas');
    const html = document.getElementById('capture').innerHTML;
    rasterizeHTML.drawHTML(html, canvas);
};

      3. Setup HTML and Canvas

      <canvas id="myCanvas"></canvas>
<button onClick={renderToCanvas}>Render to Canvas</button>

      Native JavaScript Approach

      Without external libraries, use SVG and Blob APIs:

      1. Capture and Convert Function
      const captureDOM = () => {
    const svgData = new XMLSerializer().serializeToString(document.getElementById('capture'));
    const svgBlob = new Blob([svgData], {type: 'image/svg+xml;charset=utf-8'});
    const url = URL.createObjectURL(svgBlob);

    const img = new Image();
    img.onload = function () {
        const canvas = document.createElement('canvas');
        canvas.width = this.width;
        canvas.height = this.height;
        const ctx = canvas.getContext('2d');
        ctx.drawImage(this, 0, 0);
        URL.revokeObjectURL(url);
        document.body.appendChild(canvas);
    };
    img.src = url;
};

      2. HTML and Button

      <button onClick={captureDOM}>Capture DOM</button>
