Changelog

Have a look at the releases page: https://github.com/marcbachmann/node-html-pdf/releases

Installation

Install the html-pdf utility via npm:

$ npm install -g html-pdf

Command-line example

$ html-pdf test/businesscard.html businesscard.pdf

Code example

var fs = require('fs');
var pdf = require('html-pdf');
var html = fs.readFileSync('./test/businesscard.html', 'utf8');
var options = { format: 'Letter' };

pdf.create(html, options).toFile('./businesscard.pdf', function(err, res) {
  if (err) return console.log(err);
  console.log(res); // { filename: '/app/businesscard.pdf' }
});

API

var pdf = require('html-pdf');
pdf.create(html).toFile([filepath, ]function(err, res){
  console.log(res.filename);
});

pdf.create(html).toStream(function(err, stream){
  stream.pipe(fs.createWriteStream('./foo.pdf'));
});

pdf.create(html).toBuffer(function(err, buffer){
  console.log('This is a buffer:', Buffer.isBuffer(buffer));
});


// for backwards compatibility
// alias to pdf.create(html[, options]).toBuffer(callback)
pdf.create(html [, options], function(err, buffer){});

Footers and Headers

html-pdf can read the header or footer either out of the footer and header config object or out of the html source. You can either set a default header & footer or overwrite that by appending a page number (1 based index) to the id="pageHeader" attribute of a html tag.

You can use any combination of those tags. The library tries to find any element, that contains the pageHeader or pageFooter id prefix.

<div id="pageHeader">Default header</div>
<div id="pageHeader-first">Header on first page</div>
<div id="pageHeader-2">Header on second page</div>
<div id="pageHeader-3">Header on third page</div>
<div id="pageHeader-last">Header on last page</div>
...
<div id="pageFooter">Default footer</div>
<div id="pageFooter-first">Footer on first page</div>
<div id="pageFooter-2">Footer on second page</div>
<div id="pageFooter-last">Footer on last page</div>
