Issue

Previously without this module we would boot fastify as follows:

const server = await initServer()
server.listen({ port: server.config.port, host: server.config.host }

With restartable, this looks like:

const server = await restartable(initServer, { logger: true })
// How to read server.config.port?

How does one access the underlying server object to read things like .config? The wrapper seems to return an object { then: undefined } which has the apps prototype copied over.

restartable/index.js

Line 9 in 0b02b0d

const proxy = { then: undefined }

Currently I see:

TypeError: Cannot read properties of undefined (reading 'port')
    at app.js:55:45
    at processTicksAndRejections (node:internal/process/task_queues:96:5)

I got to the bottom of my issue, and I believe it's a bug in this module, proposed fix in #46

Here is an example: https://github.com/fastify/restartable#usage

const app = await restartable(createApp, { logger: true })
const host = await app.listen({ port: 3000 })
