Generating PDF through an html template

[sumit-popclub]

I have a html template in which I will render data on the runtime and want to generate a pdf out of it. Is there any way I can do that using go fpdf.

this is my code

func usingGoFPDF() {
	now := time.Now()

	tmpl, err := template.ParseFiles(templateFileName)
	if err != nil {
		log.Fatalf("could not parse template: %v", err)
	}

	fmt.Println("template parsed", time.Since(now))

	var result bytes.Buffer

	data := AadharDetails{
		PhotoSrc:      "photo.jpg",
		FormId:        "1234567890",
		AadhaarNumber: "1234 5678 9012",
		FirstName:     "John",
		FatherName:    "Doe",
		DOB:           "01-01-2000",
		ContactPerson: "John Doe",
		Gender:        "Male",
		MobileNumber:  "1234567890",
		EmailId:       "[email protected]",
		Address:       "123, XYZ Street, ABC City, DEF State, 123456",
		HouseNo:       "123",
		Landmark:      "Near ABC",
		City:          "ABC",
		Street:        "XYZ",
		PostOffice:    "DEF",
		District:      "GHI",
		SubDistrict:   "JKL",
		State:         "MNO",
		Pincode:       "123456",
		Country:       "India",
	}

	fmt.Println("data set", time.Since(now))

	err = tmpl.Execute(&result, data)
	if err != nil {
		log.Fatalf("could not execute template: %v", err)
	}

	fmt.Println("template executed", time.Since(now))

	htmlData := result.String()

	// Create a PDF document
	pdf := fpdf.New("P", "mm", "A4", "")

	// Add a new page
	pdf.AddPage()

	fmt.Println(htmlData)
	pdf.Write(1.2, htmlData)

	err = pdf.OutputFileAndClose("output.pdf")
	if err != nil {
		log.Fatal(err)
	}

	fmt.Println("Time taken:", time.Since(now))
	fmt.Println("PDF generated successfully:", "output.pdf")

}

It's breaking with the error - panic: runtime error: index out of range [60] with length 0

apologies for the belated answer.

do you have an as simple as possible reproducer ? (so I could play a bit with that ?)

Any html page will do.. I am also searching for a weasyprint(python) replacement in Go.
