A Node.js wrapper for the wkhtmltopdf command line tool. As the name implies, it converts HTML documents to PDFs using WebKit.
var wkhtmltopdf = require('wkhtmltopdf');
// URL
wkhtmltopdf('http://google.com/', { pageSize: 'letter' })
.pipe(fs.createWriteStream('out.pdf'));
// HTML
wkhtmltopdf('<h1>Test</h1><p>Hello world</p>')
.pipe(res);
// output to a file directly
wkhtmltopdf('http://apple.com/', { output: 'out.pdf' });
// Optional callback
wkhtmltopdf('http://google.com/', { pageSize: 'letter' }, function (err, stream) {
});
// Ignore warning strings
wkhtmltopdf('http://apple.com/', {
output: 'out.pdf',
ignore: ['QFont::setPixelSize: Pixel size <= 0 (0)']
});
// RegExp also acceptable
wkhtmltopdf('http://apple.com/', {
output: 'out.pdf',
ignore: [/QFont::setPixelSize/]
});wkhtmltopdf is just a function, which you call with either a URL or an inline HTML string, and it returns
a stream that you can read from or pipe to wherever you like (e.g. a file, or an HTTP response).
There are many options available to wkhtmltopdf. All of the command line options are supported as documented on the page linked to above. The options are camelCased instead-of-dashed as in the command line tool.
There is also an output option that can be used to write the output directly to a filename, instead of returning
a stream.
First, you need to install the wkhtmltopdf command line tool on your system. The easiest way to do this is to download a prebuilt version for your system. Don't try to use the packages provided by your distribution as they may not be using a patched Qt and have missing features.
Finally, to install the node module, use npm:
npm install wkhtmltopdf
Be sure wkhtmltopdf is in your PATH when you're done installing. If you don't want to do this for some reason, you can change
the wkhtmltopdf.command property to the path to the wkhtmltopdf command line tool.
