    go-wkhtmltopdf

    go-wkhtmltopdf

    Golang commandline wrapper for wkhtmltopdf

    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.
