Do you believe that creating a complete invoice document can take less than 200 lines of code? We have prepared for you a step-by-step instruction that shows every detail of this implementation and describes the best patterns and practices. This library is created specifically for designing and arranging document layouts, with full paging support. Alternative solutions, such as HTML-based converters, are not designed for this purpose and therefore are often unpredictable and do not produce desired results.

HTML to PDF or image (jpeg, png, webp) converter via Chrome/Chromium. This library is NOT meant to accept untrusted user input. Doing so may have serious security risks such as Server-Side Request Forgery (SSRF). If you run into CORS issues, try using the --disable-web-security Chrome flag, either when you start Chrome externally, or in options.chromeFlags. This option should only be used if you fully trust the code you are executing during a print job. It is strongly recommended that you keep Chrome running side-by-side with Node.js. There is significant overhead starting up Chrome for each PDF generation which can be easily avoided. By default, pages are saved as a PDF. To save as a screenshot instead, supply screenshotOptions. You can optionally provide an HTML template for a custom header and/or footer. There are a few CompletionTrigger types that wait for something to occur before triggering PDF printing.
