Hi,

I'm having an issue with JSReport Docker image, which causes the browser to freeze 9 out of 10 times (if I reload the tab in a different window 1 of 10 times it WILL load and work successfully). Tested on Chrome & Edge, and in two different machines.

Looks like the below when it happens and can't do anything (plus Chrome notifies that the browser is stuck).

Any help appreciated! (I'm a licensed user)

you are a saint!

One issue I was struggling with was how to add dynamic data to headers/footers in Chrome-PDF without having to resort to using pdf-tools, which are slow and extremely inefficient for long documents using the same data. I've found a nice little hack that allows me to do so now:

1. Add a template (let's call it DynamicHeaderTemplate) with your header template, including dynamic data-handling tags.
2. Add a script (let's call it DynamicHeaderScript) and reference it from your main template with the following code:

const proxy = require('jsreport-proxy');
var headerTemplate = null;

async function beforeRender(req, res) {
    if (!req.context.isChildRequest) {
        if (headerTemplate === null) {
            const result = await proxy.render({ template: { name: 'DynamicHeaderTemplate', recipe: 'html' }, data: req.data });
            headerTemplate = result.content.toString();
        }
 
        req.template.chrome.headerTemplate = headerTemplate;
    }
}

What this essentially does is calls the DynamicHeaderTemplate template before render, with the data structure for your main template. The resulting HTML replaces the chrome-pdf header html.

Solved: Page <span class="pageNumber"></span> of <span class="totalPages"></span>

I've tried using {#pageNum} and javascript (which worked in wkhtmltopdf I believe)
