tls property in Bun.serve not available after 1.2.3 or higher

[SPWizard01]

What version of Bun is running?

1.2.4+fd9a5ea66

What platform is your computer?

Microsoft Windows NT 10.0.26120.0 x64

What steps can reproduce the bug?

bun i @types/[email protected]

Bun.serve({
//... skipping for simplicity
 tls: undefined // works
})

bun i @types/[email protected]

observe that now typescript throws an error

What is the expected behavior?

tls property should be recognized

What do you see instead?

Object literal may only specify known properties, and 'tls' does not exist in type '((Omit<ServeOptions, "routes"> & { routes?: undefined; fetch: (this: Server, request: Request, server: Server) => Response | Promise<...>; }) | (Omit<...> & { ...; }) | WebSocketServeOptions<...>) & { ...; }'

Hi there! I've been able to reproduce this issue.

The problem is that the TypeScript definitions for Bun.serve() don't properly include the TLSServeOptions interface. The tls property works correctly at runtime, but the TypeScript type checker doesn't recognize it as a valid property.

The issue appears to have been introduced in a recent version of the type definitions. Looking at the code, I see that the serve() function signature doesn't include TLSServeOptions in its union of parameter types.

I've created a reproduction case that confirms this behavior. For now, you can work around this by adding a type assertion:

Bun.serve({
  // other options
  tls: undefined,
  fetch: (req) => new Response("Hello")
} as any);

I'll create a fix for this issue to ensure the tls property is properly typed. Thank you for reporting!
