Express.js PDF API: From HTML to PDF in 30 Seconds Express.js remains the most widely used Node.js framework for building APIs. It has earned that position by staying out of your way. You define routes, wire up middleware, and ship. PDF generation should be just as straightforward. In practice, it rarely is. Teams burn days configuring Puppeteer, managing headless Chromium processes, handling zombie browsers, and debugging font rendering. All of that complexity exists below the abstraction layer you actually care about: give me HTML, give me back a PDF. DocuForge eliminates that entire layer. You send HTML (or a template, or JSX) to a single API call and get a production-ready PDF back. No browser binaries. No process management. No memory leaks at 3 AM. In this tutorial, you will build a PDF microservice with Express.js that exposes four endpoints: HTML-to-PDF generation, template-based invoice rendering, direct file downloads, and React-to-PDF conversion.
