What is jsPDF?

jsPDF is a JavaScript library that allows you to generate PDF files directly in the browser. This library is lightweight, easy to use, and has become the go-to solution for creating PDF documents on the client side without needing any server-side processing.

With jsPDF, you can add text, images, and tables to your PDFs and even customize fonts and styles to create professional-quality documents.

Integrating jsPDF into Your Web Application

To use jsPDF, you first need to include its library in your project. There are two ways to do this:

Via a CDN link(recommended for quick testing).
By downloading the libraryand hosting it yourself.

Here’s how to include jsPDF using CDN links:

html

Creating the “Download as PDF” Button

Now that we’ve included jsPDF in our project, we can create a button that will allow users to download the content as a PDF. Below is an example of the HTML and styling for this button:

html

CopyEdit

Download as PDF

</button>

</div>

Button Explanation:

Text Alignment: The button is aligned to the right using text-align: right;.
Styling: The button has a custom color (#172d88), and the text color is set to white (color: white;).

Generating the PDF on Button Click

To make this button functional, we’ll write a JavaScript function using jsPDF to generate the PDF when the button is clicked.

Here’s an example of the JavaScript code:

javascript

CopyEdit

document.getElementById(‘downloadPdfBtn’).addEventListener(‘click’, function() {

const { jsPDF } = window.jspdf; // Access jsPDF from the global object

const doc = new jsPDF();

// Adding text to the PDF

doc.text(“Hello, this is a PDF generated from your web content!”, 20, 30);

// Optionally, you can add tables or other content

doc.autoTable({

head: [[‘Column 1’, ‘Column 2’]],

body: [

[‘Row 1 Data’, ‘More Data’],

[‘Row 2 Data’, ‘More Data’]

]

});

// Save the PDF

doc.save(‘downloaded-content.pdf’);

});

Customizing the PDF Output

You can customize your PDF output in many ways using jsPDF. Here are a few common customizations:

Font Style:

javascript

CopyEdit

doc.setFont(‘times’, ‘normal’);

Adding Images:

javascript

CopyEdit

doc.addImage(imgData, ‘JPEG’, 15, 40, 180, 160);

Page Size and Orientation:

javascript

CopyEdit

const doc = new jsPDF(‘p’, ‘mm’, ‘a4’); // Portrait, A4 size

Adding Links:

javascript

CopyEdit

doc.textWithLink(‘Click Here’, 10, 20, { url: ‘https://example.com’ });

Conclusion

With jsPDF, you can easily integrate a feature into your web application that allows users to download content in PDF format, all without needing any server-side processing. Whether it’s for reports, invoices, or simple text content, jsPDF provides a flexible and efficient solution for generating PDFs directly in the browser.

By combining jsPDF with features like tables, images, and text customization, you can create professional-looking documents that suit a variety of needs.
