In today’s digital world, being able to create a printable PDF from a webpage can be extremely beneficial. Whether you’re compiling a report, creating an invoice, or generating a resume, the dom-to-pdf library empowers developers to effortlessly transform DOM elements into PDF files. In this article, we’ll guide you through the installation, usage, and options available within this versatile tool.

Installation

To get started, you’ll need to install the dom-to-pdf library. You can easily do this using npm by running the following command:

npm install --save dom-to-pdf

Usage

Once you have the library installed, you can begin using it. Here’s a quick example:

var domToPdf = require('dom-to-pdf');
var element = document.getElementById('test');
var options = { filename: 'test.pdf' };

domToPdf(element, options, function(pdf) {
    console.log('done');
});

In this code snippet, think of the DOM node as a piece of furniture in a room. The dom-to-pdf library is like a magical service that, when called, wraps that piece of furniture in nice paper and transforms it into a beautiful package (the PDF) that can be easily shared or presented. The options are like instructions on how you want that package presented, including the name of the package (PDF file).

Options

When utilizing dom-to-pdf, you can configure various options to tailor the PDF output to your needs. Below is a list of available options:

• filename: The name of the resulting PDF file. Default is generated.pdf.
• excludeClassNames: An array of strings, indicating class names of elements to exclude from the PDF (e.g., [Loading, ExcludeMeFromPdf]).
• excludeTagNames: An array of strings, indicating HTML tags to exclude from the PDF (e.g., [button, input, select]).
• overrideWidth: A number that overrides the width of a container DOM element.
• proxyUrl: A string used to avoid CORS problems (e.g., apiproxyImage?url=).
• compression: The compression level of the generated image, with options including NONE, FAST, MEDIUM, and SLOW. Default is NONE.
• scale: A number that increases image size before exporting to improve quality.

Troubleshooting

While working with dom-to-pdf, you may encounter a few common issues. Here are some troubleshooting tips:

• PDF not generating: Ensure that the DOM element you are trying to convert exists and is correctly referenced.
• Incorrect size/scale: Check the scale option; adjusting this can improve the image quality in the PDF.
• CORS issues: If images are not appearing in the PDF, ensure you correctly set the proxyUrl option to handle CORS.
• File permissions: Make sure that your application has permissions to write files in the designated output folder.
