Adds basic Vue 3 compatibility

[veryeasily]

This pull request adds Vue 3 compatibility which should fix #284.

Previously this fix was open as #287 but seems like it was maybe prematurely closed. I tested my changes out and they appear to work on both Vue 3 and Vue 2.

As a warning though, my vue 3 tests have not been super thorough because my application is having vue 3 problems with unrelated dependencies. This PR gets past the initial issue, but there may still be deeper problems to debug.

Is this fix confirmed to be working?

Is this fix confirmed to be working?

Yes, it does fix the error reported in #284. While waiting for the pull request to be accepted I forked the repo and pushed a custom build of the plugin, because I needed it asap.

Thanks! I think I find myself in the same boat.

Thanks! I think I find myself in the same boat.

Actually, I forgot to add that the typings are also broken, if you're using Typescript.

The absolute minimum required to get everything to work is a definition of the custom properties:

declare module '@vue/runtime-core' {
    interface ComponentCustomProperties {
        $socket: SocketIO.Socket,
    }
}

I placed this declaration in my app entrypoint. I found this solution on stackoverflow.

Happy to see this merged too.

thanks for merging! I tried running npm update vue-socket.io and it still doesn't seem to be working

@wkuinkc try changing your dependency to point to this repo instead of the npm package; the latest release goes back to August of last year

@MetinSeylan, the NPM version doesn't seem up to date. Is there an upcoming update ? It would be greatly appreciated !
