Thankfully the google project page hosts a batch of static binaries that work on just about every platform. The hard part is getting the wkhtmltopdf binaries for you platform installed. Installing the PDFKit gem is a no brainer. ![]() But many topics will apply to both PDFKit and WickedPdf since they use wkhtmltopdf on the backside. In this article I am only going to focus on PDFKit with Rails. ![]() This is the muscle behind the PDFKit gem and other projects like WickedPdf. Wkhtmltopdf is an open source project that uses the WebKit rendering engine to convert HTML to native PDF code. Sure there are gems like Prawn that make this much easier, but nothing beats drawing your pdf code in native HTML and CSS, and that is where wkhtmltopdf comes in. In short, its a damn chore that involves a bunch of code that mixes both data and presentation. Why? Well drawing pdfs in ruby using libraries like PDF::Writer is like composing a webpage with an Etch A Sketch. Last week I had the pleasure of rewriting 4 years of legacy PDF::Writer code to PDFKit. (Use Firefox if you can, or try the demo on my personal site).Ruby, JavaScript, Sass, iOS. Note that, since CodePen loads the result page in an iframe, the PDF preview – which is loaded in an iframe too – has some issues with Chrome and Safari that prevent the preview from being displayed. This is an example of a PDF created with the app (photo credit: Rafael Leão / Unsplash)Ī functioning demo is available at the end of this article or directly in CodePen. The demo works well with Firefox and Chrome, while Explorer (or Edge) doesn’t allow you to display the preview, but only to download the generated PDF. I’ve rearranged that application for this article, removing all server-side functionality, simplifying the flyer design, getting rid of legacy browser compatibility and building a very simple UI with Bootstrap 3 and jQuery. The flyer’s main aim was to provide a simple way to display special offers to be exposed in the travel agency shop window. It was part of a larger project that dealt with some services for travel agencies, and the real flyer was partially populated by some JSON data. Some months ago, I was asked to build an application for creating some simple flyers. pdfmake seems to be well documented and very easy to use, but since it was a beta version, I decided for jsPDF. When I started my project, some months ago, I searched for a JS library, and finally I found two candidates: jsPDF and pdfmake. ![]() Unfortunately, the library seems to be abandoned (its last version dates back to 2011) (Update: actually, the latest version appears to be from December 2015), but thanks to some JavaScript libraries, we now have the ability to build PDF files directly in the clients (thus making their generation faster). In the past I’ve often used FPDF, a PHP tool that can easily give you such controls and that can be easily expanded with many plugins. (I’ve tried several tools of that type, but none of them has fully satisfied me.) My goal is to have complete control over the positioning and size of elements, page breaks and so on. I’m not talking here about the simple conversion of HTML to PDF. Therefore, when I need to build something that must be printed, I always try to avoid CSS, and the simplest solution is to use PDF. Anyone who has dealt with CSS printing rules knows how difficult it is to achieve a decent level of cross-browser compatibility (take a look, for example, at the Page-break support table at Can I Use).
