Start chrome with pm2
If you don’t have pm2, install it first.
pm2 start google-chrome \ --interpreter none \ -- \ --headless \ --disable-gpu \ --disable-translate \ --disable-extensions \ --disable-background-networking \ --safebrowsing-disable-auto-update \ --disable-sync \ --metrics-recording-only \ --disable-default-apps \ --no-first-run \ --mute-audio \ --hide-scrollbars \ --remote-debugging-port=44443 \ --no-sandbox
You can use your own port (change 44443 to your own port)
Now you can use module html-pdf-chrome:
All available printOptions:
landscape : Paper orientation. Defaults to false.
displayHeaderFooter : Display header and footer. Defaults to false.
printBackground : Print background graphics. Defaults to false.
scale : Scale of the webpage rendering. Defaults to 1.
paperWidth : Paper width in inches. Defaults to 8.5 inches.
paperHeight : Paper height in inches. Defaults to 11 inches.
marginTop : Top margin in inches. Defaults to 1cm (~0.4 inches).
marginBottom : Bottom margin in inches. Defaults to 1cm (~0.4 inches).
marginLeft : Left margin in inches. Defaults to 1cm (~0.4 inches).
marginRight : Right margin in inches. Defaults to 1cm (~0.4 inches).
pageRanges : Paper ranges to print, e.g., '1-5, 8, 11-13'.
Defaults to the empty string, which means print all pages.
ignoreInvalidPageRanges : Whether to silently ignore invalid but successfully parsed
page ranges, such as '3-2'. Defaults to false.
headerTemplate : HTML template for the print header.
Should be valid HTML markup with following classes used to inject printing values into them:
- `date` formatted print date
- `title` document title
- `url` document location
- `pageNumber` current page number
- `totalPages` total pages in the document
For example, `<span class="title"></span>` would generate a span containing the title.
footerTemplate : HTML template for the print footer. Should use the same format as the `headerTemplate`.
preferCSSPageSize : Whether or not to prefer page size as defined by css.
Defaults to false, in which case the content will be scaled to fit the paper size.
See Example 2 to know how to use printOptions.
Example 1: convert HTML code to PDF
const htmlPdf = require('html-pdf-chrome');
const html = '<p>Hello, TUTORIALSPOTS!</p>';
const options = {
port: 44443, // port Chrome is listening on
};
htmlPdf.create(html, options).then((pdf) => pdf.toFile('pdf1.pdf'));
//htmlPdf.create(html, options).then((pdf) => pdf.toBase64());
//htmlPdf.create(html, options).then((pdf) => pdf.toBuffer());
//htmlPdf.create(html, options).then((pdf) => pdf.toStream());
Result: http://demo.tutorialspots.com/nodejs/html-pdf-chrome/pdf1.pdf
Example 2: use an external site
const htmlPdf = require('html-pdf-chrome');
const options = {
port: 44443, // port Chrome is listening on
printOptions: {printBackground: true}
};
const url = 'http://tutorialspots.com/';
htmlPdf.create(url, options).then((pdf) => pdf.toFile('pdf2.pdf'));
Result: http://demo.tutorialspots.com/nodejs/html-pdf-chrome/pdf2.pdf
