re: Thank you for all of your replies, Richard. This has set me up well!

Actually, I apologize for my answer to the second question. I realize I may have misspoke to quickly and perhaps stated something that could be incorrect. In the current implementation of the plugin, this is what is going on in the emitter:

  await runHook(ctx, pre) // run the pre-emit hook
  return new Promise((resolve, reject) => {
    ...
    // Emit the event "emitEvt" with msg:
    socket.emit(emitEvt, msg, (resp) => { 
      // Handle response
    })
    ...
  })

So, the plugin is currently not checking the return value of the runHook, but I guess the next version can check for a validation value (true or false). If validation fails, the emitter should not emit the event. However, to prevent breaking code for existing users of the plugin, it should only operate on the return value if it's defined (I'll keep thinking about this). The other design challenge is: do I treat the return value as a validation value or as data that should be propagated to the emit "msg"? Maybe some happy combination can be made.

But, back to your question...so for now since the plugin does't check the pre-emit hook's validation value, you would just update your code as follows:

nuxt.config:

// emitters: [ 'checkBeep] beep + msg --> resp' ] // old
emitters: [ 'beep + msg --> resp' ] // workaround

And then in your component.js:

checkBeep() { // You'd still have this method defined
  if (this.inputValid) {
    // valid input:
    this.beep() // "beep" gets emitted with "msg"
  }
}

This way, you can still have checkBeep defined, but just omit it from the nuxt.config entry so that the plugin doesn't call it. I know going forward, it will be cleaner to let the plugin do it, so I'll just need some time to think about it. (the challenge is when a lot of people have already downloaded it, there's a small risk I'll break there existing code, so I just have to take that into consideration too)
