const doc = new PDFDocument({
    layout: "landscape",
    size: "A4",
});

// The name
const name = "Sophia Sweet"

// Pipe the PDF into an name.pdf file
doc.pipe(fs.createWriteStream(`${name}.pdf`));

// Draw the certificate image
doc.image("images/certificate.png", 0, 0, { width: 842 });

// Remember to download the font
// Set the font to Dancing Script
doc.font("fonts/DancingScript-VariableFont_wght.ttf");

// Draw the name
doc.fontSize(60).text(name, 20, 265, {
    align: "center"
});

// Draw the date
doc.fontSize(17).text(moment().format("MMMM Do YYYY"), -275, 430, {
    align: "center"
});

// Finalize the PDF and end the stream
doc.end();
