Upload files via HTTP using FormData

To upload files over HTTP with Bun, use the FormData API. Start with an HTTP server that serves an HTML form.

Stream a file as an HTTP Response

Bun.file() reads a file from disk and returns a BunFile instance, which you can pass directly to the new Response constructor.

fetch with unix domain sockets in Bun

In Bun, fetch() can send HTTP requests over a unix domain socket with the unix option.
