[✨] Throw server$ errors with a specific status code

[DustinJSilk]

Is your feature request related to a problem?

Currently all server$ errors return an HTTP 500 error which can't be configured per request.

Describe the solution you'd like

I'd like to be able to throw a custom error which includes a status code.

Option A:

import { ServerError } from `@builder.io/qwik-city`

const myFunc = server$(() => {
  throw new ServerError(404, { /** Some response data */ })
})

Option B:

const myFunc = server$(() => {
  throw this.error(404, { /** Some response data */ })
})

Describe alternatives you've considered

Currently the choices are:

• Return 200 with a union type for both a successful and unsuccessful response
• Throw an error that is always a 500

Additional context

No response

I like it and prefer option A

ok I have it here. but you have to make sure you know how to detect the error from the response object json
#6290

this will only work for any status that fails res.ok and not 500 status

const myFunc = server$(() => {
  if (throwing) {
    throw new ServerError(404, { error: true, data: {} })
  }
  return { error: false, data: {}}
})


const data = await myFunc()
if (data.error) {
  console.log(data.error)
}

this pattern should be way better

const myFunc = server$(() => {
  if (throwing) {
    const errorData = {};
    throw new ServerError(404, [ errorData ])
  }
  const data = {};
  return [null, data]
})


const [err, data] = await myFunc()
if (err) {
  console.log(err)
}

Amazing, thank you @PatrickJS !

[PatrickJS]

you have to import from import { ServerError } from "@builder.io/qwik-city/middleware/request-handler"; in the next release
