Uniquely identify a server instance with an ID

When bun is started with the --hot flag:

This string will be used to hot reload the server without interrupting pending requests or websockets. If not provided, a value will be generated. To disable hot reloading, set this value to null.

When bun is not started with the --hot flag:

This string will currently do nothing. But in the future it could be useful for logs or metrics.

What is the maximum size of a request body? (in bytes)

Set options for using TLS with this server

const server = Bun.serve({
fetch: request => new Response("Welcome to Bun!"),
tls: {
cert: Bun.file("cert.pem"),
key: Bun.file("key.pem"),
ca: [Bun.file("ca1.pem"), Bun.file("ca2.pem")],
},
});

If set, the HTTP server will listen on a unix socket instead of a port. (Cannot be used with hostname+port)
