If you want to generate a PDF from the Google homepage, you can run: require "pdfkit" PDFKit also allows you to generate a PDF from a URL. You should have a new file called hello.pdf with the text at the top.
#PDFKIT RUBY INSTALL#
You also need to install the pdfkit gem, and then run the following bit of Ruby to generate a PDF with the text “Hello Envato!” require "pdfkit" You can download the binary or install from Brew on Mac, or your preferred Linux repository. To start, install wkhtmltopdf on your computer. Internally, PDFKit uses wkhtmltopdf (WebKit HTML to PDF), an engine that will take HTML and CSS, render it using WebKit, and output it as a PDF with high quality. Chances are that you are already familiar with HTML and CSS, so we are going to use PDFKit to generate PDF files using HTML from standard Rails view and style code. So when you want more control on the PDF document and if the PDF has multiple pages and involves more complexities, then PRAWN PDF would be the right gem, but when it comes to a single pager that involves lots of images/charts then PDFkit will be the right choice.There are many ways to generate PDFs in Ruby and Rails. If you have a view and want to just convert to pdf, then gems like PDFkit will help, HTML to PDF can be simpler.
#PDFKIT RUBY CODE#
There are some limitations in PRWAN PDF, We cannot draw everything we wanted in PRAWN, say pie chart, which involves lots of code to be written, at this point it would be good to go with HTML to PDF convertor.Īs I already stated, picking the gem is based on preference and project requirements. This is possible since PrawnPDF works based on gird layout, which helps us to be more precise. PRAWN Pdf has lots of api methods to draw shapes like, circle, rectangle, move from one point to other point and measurements based on. Here i have shared the code to repeat the header in all pages, We would be able to define colors, add html content, set width, height, alignment, text color and so on.Ĭode to generate table, where we would be able to define, header, width of each and every cell in the table, style and color of the row.
#PDFKIT RUBY MANUAL#
Prawn PDF has a very nice manual explaining each and every api methods. PrawnPdf is one of the fastest PDf generators available for Ruby, refer ruby-toolbox Finally we got a reliable and clean output. Then we tried Prawn PDF, which I will say is really really cool and awesome 🙂, when it comes to more specific requirements(fixed header footer, repeat table header in all the pages, separate footer in the last screen), We will have more control on the pages, but we need to do some coding to achieve this. We looked for solution and found out few googling, like page breaks using css and few other stuff to achieve this, but it did not help us a lot. But when the requirement became more specific and the table started growing, html to pdf was not of help anymore, We din’t have much control over the document.
The coding stuff was done in the view part and converted the html to pdf. We got a requirement for a project to generate pdf for a report module, Initially without too much investigation we directly went with wicked PDF, which got a simple and straight forward solution for our basic need. Here am not going to explain about all 3 gems, but I am going to share my experience with Prawn PDF.
The list of libraries or gems that are available in Ruby There are some straight forward ways to download the data in PDF format, say directly converting the html to pdf, which is one of the simplest ways. Users would like to download their data as pdf or excel and there are only few libraries available in Ruby to achieve this, but it depends on the requirement. Generating pdf is a common requirement in web applications, mostly to download reports.
