If you need to generate PDFs from HTML in a production app, you have two options: run a local rendering tool yourself (Puppeteer, Playwright, wkhtmltopdf) or call an HTML to PDF API that does the rendering for you. This tutorial covers the API approach with a complete Node.js example that generates invoice PDFs using EJS templates and the PDFBolt API. You will also find a comparison with headless browser solutions to help you pick the right tool for your project.

Most web applications talk to each other through APIs. If you've ever pulled data from a third-party service, processed a payment, or generated a PDF from HTML, you've used one. But the terminology around APIs can get confusing fast: REST vs. SOAP vs. GraphQL, synchronous vs. asynchronous, public vs. internal. This guide breaks it down with clear definitions, architecture comparisons, and a working Node.js code example at the end.
