🚀 Feature Proposal

For now it must be string or array of strings, but modern Node.js also supports URL for many APIs. It would be great to support it here too.

Motivation

root: new URL(".", import.meta.url) (or .toString()) fails because neither of URL nor file: protocol is supported. fileURLToPath is always required.

Example

fastify.register(fastifyStatic, {
  root: new URL("assets/", import.meta.url)
});
