io is not a function

[standfv]

My issues: io is not a function.
When used custom.
const io = useIO()
const socket2 = io('http://localhost:3069')

[pavlienko]

have the same problem

[huangbh1024]

onMounted(() => {
	const io = useIO();
	const socket = io("http://127.0.0.1:7001/onlineCount");
});

is useful to me

I have published a new version. This does not fix it but uses the latest Nuxt version.

For the meantime, you can do what @huangbh1024 did, or

const { $io } = useNuxtApp()

const connected = ref(false)

onMounted(() => {
  const socket = $io('http://localhost:3069/');

  socket.on('connect', () => {
    connected.value = socket.connected
  })

  socket.on('disconnect', () => {
    connected.value = socket.connected
  })
})

I'll deprecate this feature soon in favor of this.

@wobsoriano Is there a production version of this working? I get this error when I run build followed by node .output/server/index.mjs

$ node .output/server/index.mjs 
node:internal/errors:496
    ErrorCaptureStackTrace(err);
    ^

@BayBreezy looks like I have to test it on windows 🫣

[BayBreezy]

@wobsoriano oh ok cool.. Would love if this worked in production lol.
Let me know what you find when you get the time. Thanks 🙏🏽

[wobsoriano]

@BayBreezy thanks for confirming that it's not working in production build on windows!

[BayBreezy]

@wobsoriano I can confirm that the built version works on a mac 👍🏽

When deployed to Netlify, it does not work. ❌

When deployed on Ubuntu Server, it works fine. ✅

When deployed behind nginx it also works fine. ✅

Sadly I don't have a paid heroku account to test it on

I have not stress tested it yet but the few emits and listeners work great. Thanks for the module

[BayBreezy]

Confirming that it works on render.com too

@Donny2333 Were you able to get yours working?
Having the same issue on windows still.
