描述

I use this Puppeteer microservice to generate receipts in PDF. For each receipt, width is always the same, but height changes, according to the article count in the order.

For now, I'm using the article count to approximate the required height for my receipt. It kind of works, but it's not perfect and is a dirty way to do. Is there way to tell Puppeteer API : "Please automatically find the right PDF height, according to the HTML body height, in order to generate a perfectly sized PDF" ?

研究方向
Investigate Puppeteer's page.pdf options to see if an automatic height feature exists (e.g., a 'height: 0' or 'auto' setting). If not, use page.evaluate to measure the page's scrollHeight (document.body.scrollHeight) and pass that value to the height option. Review the service's existing code in the index.js file to see how PDF options are currently passed and adjust accordingly. Check linked issues or discussions for prior attempts or solutions.
