html2pdf
This is a fork of MhmoudGit/html2pdf that implements some features such as disabling external javascript scripts, as well as disabling internal javascript, so you do not need to worry about it hanging from someone injecting a script tag, or having anything exposed.
How to use
View original ReadMe here
html2pdf is a Go package designed specifically for converting HTML content to PDF documents. It wraps the functionality of Rod for browser automation and pdfcpu for PDF generation, providing a simple and efficient way to create PDFs from HTML content.
-
this is very simple code, basically a wrapper, for my personal usage as i struggled to find easy go library to suit my needs for converting html to pdf
-
it is not a perfect solution and not yet completed and probably have bugs :)

<h1 style="color: red">{{.ID}}</h1>
<p style="color: green; font-weight: bold">{{.Item}}.</p>
</body>

`
func main() {
// directory for saving generated data
tempDir := "files"
// the final output
mergedPdf := "example.pdf"
todos := []Todo{
{ID: 1, Item: "First item"},
}
template, err := template.New("todo").Parse(tmpl)
if err != nil {
fmt.Println(err)
}
// create a pdf generator
g := html2pdf.Generator[Todo]{
OutputPath: tempDir,
FinalPdf: mergedPdf,
Template: template,
Data: todos,
DisableAllScripts: true,
}
// generate pdf
err = g.CreatePdf()
if err != nil {
fmt.Println(err)
}
