We needed a way to generate PDF documents from Go. These vary from invoices with highly customizable layouts to reports with tables, graphs and images. In our opinion, the best way to do this was by using HTML/CSS templates as a source for our PDFs. Using CSS print media types and millimeters instead of pixel units we can generate very accurate PDF documents using wkhtmltopdf. It takes care of setting the correct order of options as these can become very long with multiple pages where you have page and TOC options for each page. It makes usage in server-type applications easier, every instance (PDF process) has its own output buffer which contains the PDF output and you can feed one input document from an io.Reader (using stdin in wkhtmltopdf). You can combine any number of external HTML documents (HTTP(S) links) with at most one HTML document from stdin and set options for each input document.
Features
- Golang commandline wrapper for wkhtmltopdf
- go-wkhtmltopdf is a pure Golang wrapper around the wkhtmltopdf command line utility
- It takes care of setting the correct order of options as these can become very long with muliple pages where you have page and TOC options for each page
- ou can also ignore the internal buffer and let wkhtmltopdf write directly to disk if required for large files
- The package now has the possibility to save the PDF Generator object as JSON and to create a new PDF Generator from a JSON file
- The speed if pretty much determined by wkhtmltopdf itself
