This would generate an invoice that looks like this:įormatting through code can be pretty complex because you have a lot of numbers you have to keep in mind. TheOutput.text('Some awesome example text'. The text method actually takes in an optional option property after the string that can allow us to do things like bold, underline, oblique (“italicize”), or strike.
We would need to write quite a bit more code to format it.

TheOutput.text('Some awesome example text')Īfter that we then get a pdf that would look like this:Īgain, that’s still pretty bland. We can add text using the text method like this: const PDFGenerator = require('pdfkit') If getting json in the right format is a challenge, fabric.js can be your friend. Now we need to load some json data into the canvas then convert it to an SVG string. Then pipe it to a blob stream so changes are automatically captured as the PDF file is manipulated. TheOutput.pipe(fs.createWriteStream('TestDocument.pdf'))Īt this point, we would have a really useless pdf file that doesn’t contain anything. Create a new pdf document object using PDFKit and set some default values. pipe to a writable stream which would save the result into the same directory We then need to instantiate the library and then pipe it to the writeable stream. const pdfGenerator = require('pdfkit')Īfter that, we can start to simply use it with the core file system (commonly called fs). Using PDFKit in an existing project is pretty easy.įrom the command line / terminal we need to add it is a dependency npm i pdfkitĪfter that we can use it as a module in our project by simply requiring it. PDFKit is a library that I’ve used a few times for generating very simple invoices that a template wasn’t used for. In this post, we will cover using a library to generate the pdf using just JavaScript. We are going to cover both methods though because there are times I prefer to write a lot of code and do it.

Basically – I download the existing template and sales or marketing provides me the updates. I normally prefer to use a template that is HTML based to create pdf files because this potentially allows marketing or business users to make some of the needed changes without necessarily requiring code changes to happen. The PDFKit API is designed to be simple, so generating complex documents is often as. The API embraces chainability, and includes both low level functions as well as abstractions for higher level functionality. The first way is to use a PDF generation library that uses straight JavaScript/Nodejs and everything is untemplated or the other way is to use something templated in a language like HTML and then generate the pdf from it. PDFKit is a PDF document generation library for Node and the browser that makes creating complex, multi-page, printable documents easy. There are two major ways to approach creating a PDF file from Nodejs. It’s a really common request for businesses to be able to export a document or data into a really well-formatted PDF file whether it be an invoice or a report. The PDF format is one of the most common file formats for transmitting static information.
