🤟 A Year of Improving Node.js Compatibility in Cloudflare Workers “We’ve been busy,” says Cloudflare which recently announced it’s bringing Node.js HTTP server support to its Workers function platform. This post goes deep into the technicalities, covering what areas of the standard library is supported, how the file system works (Workers doesn’t have a typical file system), how input/output streams work, and more. And you can use all of this now. James M Snell (Cloudflare)
