Utilizing the html2canvas Library

To take a screenshot of a div, the html2canvas library serves as a valuable tool, allowing you to render the div as an image within a canvas element.

To incorporate the library, you can either add it directly to your HTML file with a script tag, like so:

Alternatively, if you're using a package manager, you can install it via NPM with the following command:

npm install --save html2canvas

Or, if you prefer Yarn, use this command:

yarn add html2canvas

Next, you can create a div that you wish to capture. For example:

<div>Hello world!</div>

To select and capture this element, you can use the following code:

const getScreenshotOfElement = async (element) => {

const canvas = await html2canvas(element);

document.body.appendChild(canvas);

};

const div = document.querySelector('div');

getScreenshotOfElement(div);

In the getScreenshotOfElement function, we pass the targeted element and call the html2canvas function, which returns a promise. Once resolved, it provides a canvas element containing the image of the specified div. We then append this canvas to the document body.

Finally, we select the div using querySelector and invoke the getScreenshotOfElement function to generate the screenshot. You should now see the canvas displaying the image of the div below the original element.
