Frequently Asked Questions

Does Workers supports React/Angular/Svelte/your frontend framework of choice?

Workers supports some server-rendered solutions for frameworks like React and Svelte. We generally suggest these solutions for power-users, and recommend that developers deploying front-end applications check out our deployment platform Cloudflare Pages.

A package that you suggested doesn't work!

Some packages may require special configuration (see the "Notes" section for each package). If a package is listed on our list that isn't supported, you can reach out to us on the Cloudflare Workers Discord server and we'll get it removed as soon as possible.

What packages don't work?

Many packages that require Node dependencies, such as fs or net/http, aren't supported in Workers because Workers isn't Node—it's built on V8.

If you're using browser packages in Workers, you should be aware that many of them refer to window—the instance of the browser window. This isn't supported in Workers (because it runs in V8, not on a browser window).
