Using React, Vue, AngularJS, or Svelte?

Why a backend helps you generate reliable PDFs from frontend frameworks

Frontend frameworks like React, Vue, AngularJS, and Svelte are great for building modern web apps. But when you need to turn web pages into PDFs, things become more complex.

When using PDF generation libraries like pdfkit or react-pdf, it's important to be aware of their limitations. These libraries may not fully support complex CSS animations, external API calls, interactive web forms, custom web fonts, third-party JavaScript libraries, dynamic content loading, responsive layouts, Canvas-based graphics, multimedia elements, and browser-specific features in the PDF output.

Some frontend-oriented tools struggle to preserve layout, styling, and dynamic content when exporting to PDF. As a result, the generated document may not match what users see in the browser.

Use a headless Chrome-based renderer

Headless Chrome solutions such as Doppio render your pages in a real browser engine. This makes them much better at preserving layout, styling, fonts, and JavaScript behavior in the final PDF.

If you need advanced print features such as margins, page numbers, running headers, and more, you can also rely on Paged.js. It is based on emerging web printing standards, and we cover it in several framework-specific articles.

How does this work with frontend frameworks?

To use Doppio or a similar service with your frontend framework, you usually need a backend layer. That backend sends requests to Doppio and returns the result to your app. You can build it in the language of your choice, whether that is Node.js, PHP, Rust, or a serverless runtime.

Why do Doppio and a backend work well together?

1. Things look the same everywhere

Doppio helps your PDFs look consistent across devices and browsers. That means fewer rendering surprises for your users.

2. More power, less stress

Backend servers are better suited than browsers for heavy rendering tasks. They can handle more demanding workloads without affecting the user's device.

3. No browser hassles

Doppio relies on a browser rendering engine, so the output is not tied to whatever browser your end user happens to use.

4. Big and Strong

If you need to generate PDFs from large volumes of data, a backend-based workflow gives you more control over scaling, retries, and background processing.

5. Keep It Safe

Sensitive data is generally safer when PDF generation is handled on the server side instead of directly in the browser.

In short, if you are using React, Vue, AngularJS, or Svelte, a headless Chrome-based service like Doppio gives you a more reliable way to generate PDFs. It improves rendering consistency, makes scaling easier, and fits naturally into a backend workflow.

By connecting your frontend application to a backend service, you can generate PDFs more predictably and keep the integration easier to maintain.
