puppeteer header and footertemplate doesnt work
Just bumped into the issue.
My observations about headerTemplate
/footerTemplate
are the following:
- At least the
font-size
has to be specified (it's set to 1px by default, which is very small):
headerTemplate: '<span style="font-size: 10px"> <span class="pageNumber"></span>/<span class="totalPages"></span></span>',
top/bottom margin must be defined to set space for the header/footer
Some CSS properties indeed don't work. I didn't have any success with
background-color
, but maybe it's because the background isn't painted for these sections.No asynchronous code (that would require an HTTP request) is allowed, such as calling a CSS stylesheet, loading an image or a font.
Consequently, CSS have to be inlined. To add an image, it can be base-64 encoded, as shown below. Concerning the fonts, we would need to rely on what is expected to be installed on the Puppeteer server I guess. Maybe there's a way to also embed it in base-64, I didn't try.
const printPDF = async () => {
const footer = `<footer style="margin: auto; width: 40%">
<img style="float: left; marginRight: 8px; marginLeft: 36px; width: 25%" src="data:image/jpeg;base64,/9j/4AAQSkZJRgAB...09Yv//Z" alt="Pivohub" />
<p style="font-family: arial; float: right; width: 55%; color: red; margin-top: 24px; font-size: 10px">
<b>My footer</b>
</p>
</footer>`
const content = `<!DOCTYPE html>
<html>
<head>
<meta charSet="utf-8"/>
<style type="text/css">
body { backgroundColor: "red" }
</style>
</head>
<body>
<h1>Hello</h1>
</body>
</html>`
const browser = await puppeteer.launch({ headless: true })
const page = await browser.newPage()
await page.setContent(content, { waitUntil: "networkidle0" })
const buffer = await page.pdf({
format: "A4",
displayHeaderFooter: true,
headerTemplate: '<span style="font-size: 10px"> <span class="pageNumber"></span> of <span class="totalPages"></span></span>',
footerTemplate: footer,
margin: { top: "100px", bottom: "200px" },
printBackground: true,
})
}
In this sample, the base 64 image was truncated. An image can be converted thanks to an online base-64 converter such as https://www.base64-image.de.
Please try the following templates:
headerTemplate: '<span style="font-size: 30px; width: 200px; height: 200px; background-color: black; color: white; margin: 20px;">Header 1</span>',
footerTemplate: '<span style="font-size: 30px; width: 50px; height: 50px; background-color: red; color:black; margin: 20px;">Footer</span>'
Not all styling properties are supported, you should avoid using position
, top
, bottom
.
Also make sure you are on the latest version of puppeteer
.
// or a .pdf file
await page.pdf({
printBackground: true,
width: `595px`, // ? 3508 x 2480 (print) || 595 pixels x 842 pixels (screen)
height: `842px`, // ? Here subraction for making alignment looks cool
margin: {
top: '25px',
bottom: '60px',
left: '25px',
right: '25px'
},
path: path.join(ROOT_PATH, 'pdf', 'report.pdf'),
displayHeaderFooter: true,
footerTemplate: `
<p style="margin: auto;font-size: 13px;">
<span class="pageNumber"></span>
/
<span class="totalPages"></span>
</p>
`
});
Hopefully, this one resolved someone's issue with the same problem. The footer was not shown before properly and finally done about a little bit search so comes with the above solution.
NOTE:
- Don't forget to mentioned
margin-bottom: 60px
(atleast).- Same for
displayHeaderFooter: true
.- Must needs to specify the
font-size: 10px
(atleast bcze default byfont-size: 0
).
