bun-http-server

Call Bun.serve with a port and a fetch handler that receives a Request and returns a Response. The server starts immediately, and you can read server.port and server.url for connection info.

Use await req.json() inside the fetch handler to parse JSON bodies. Bun also supports req.formData(), req.text(), req.arrayBuffer(), and req.blob(), but each body can only be consumed once.

Parse new URL(req.url) to get the pathname, then match it against static paths or regex patterns for dynamic segments like /api/users/:id. Combine with req.method checks to handle GET, POST, and other verbs.

Yes, pass a tls option with key and cert loaded via Bun.file to enable HTTPS. The skill also references additional TLS and mTLS configuration in its references documentation.

EADDRINUSE means the port is already occupied by another process. Either stop the conflicting process or configure Bun.serve to listen on a different port.

Return Access-Control-Allow-Origin, Methods, and Headers on every response, and handle OPTIONS preflight requests by returning an empty response with those headers. This allows browser clients from other origins to call the API.
