Thank you very much, this is exactly what I was looking for.

Is it possible to alter an existing webpage before rendering with chrome-pdf recipe? For example, if you wanted to hide the navbar of the jsreport homepage using the below script:

playground: https://playground.jsreport.net/w/reidsentry/XY6lykpe

function beforeRender(req, res) {
req.template.chrome = {
"url": "https://jsreport.net"
};
req.template.content += <script> document.querySelector('.navigation-bar').style.display = 'none'; </script>;
}

I imagine this doesn't work because the content isn't used the same when a url is set, but I don't know.
