Chapter 1: Introduction to PDF Exporting with React

Are you interested in converting a webpage into a PDF document, complete with styles and elements? This guide will walk you through the process using ReactJS, a widely-used JavaScript library for building user interfaces.

To get started, ensure that you have the necessary packages installed. We'll be utilizing Yarn, a dependable package manager for Node.js. Use the following commands in your terminal to install the required libraries:

yarn add jspdf html2canvas

The first library, jspdf, is a client-side utility that allows for PDF document creation from web content. Meanwhile, html2canvas is a JavaScript library that transforms HTML elements into canvas elements, which can subsequently be used to generate a PDF file.

With these packages set up, you can begin the process of exporting your webpage. The initial step is to pinpoint the specific element you wish to convert into a PDF. Be sure to assign it an ID attribute, which will be referenced in the exportPdf function.

Next, create a new JavaScript file similar to the provided testPage.js. In this file, you'll need to import the packages you just installed and define the exportPdf function.

Here's an example of the code you would use:

import jsPDF from 'jspdf';

import html2canvas from 'html2canvas';

const exportPdf = () => {

const element = document.getElementById('element-to-export');

html2canvas(element).then((canvas) => {

const imgData = canvas.toDataURL('image/png');

const pdf = new jsPDF();

pdf.addImage(imgData, 'PNG', 0, 0);

pdf.save('download.pdf');

});

};

In this example, we select the target element using its ID. Next, we utilize html2canvas to convert it into a canvas element. The resulting canvas is then transformed into an image, which is integrated into a new PDF document created with jspdf. Finally, the PDF is saved to the user's device.

To activate this function, you can create a button or link on your webpage and link it to the exportPdf function via its onClick event. For instance:

<button onClick={exportPdf}>Export to PDF</button>

And there you have it! With just a few lines of code, you can effortlessly export any component of your ReactJS webpage as a PDF document.
