TypeError: this.$socket.$unsubscribe is not a function

[ieshan]

Please take a look at the following link on App.vue line 38 and 39

Example Link

The $subascribe function does not exist.

Try version 4.0.0
For some reason tests were unable to catch such an issue.

Thanks for your issue BTW 👍

[ieshan]

@probil seems like the issue exists in 4.0.0 too in a different way.

When the page is loaded the first time and the Vue instance is created() the $subscribe function was available, but when I moved to another page and destroyed() called the $unsubscribe it raised TypeError. Again when I moved to the (without reloading) page the $subscribe function was not available.

Could this be the cause of it?

Probable Cause

I'm having the same issue. When I change the route and come back, the $subscribe is not available anymore.

I am still facing this issue

[ross-crowdsmart]

I am also facing this issue. Will this be fixed soon?

[zburk]

@probil Issue still not resolved. This is a pretty big issue as it renders the $subscribe and $unsubscribe useless

[probil]

It seems like introducing this.$socket.$subscribe was a mistake. 🤔

For now you can attach events directly on the socket instance, e. g.:

// subscribe
this.$socket.client.on('eventName', () => {
    // some code here
})

// unsubscribe
this.$socket.client.off('eventName', () => {
   // some code here
})

[probil]

Will try to check other use cases and probably release the next version without this.$socket.$subscribe :|

Has anyone found a solution for this? I am actively experiencing it.

@TBetcha The solution is mentioned above

// App.vue
mounted(){
  this.$socket.client.off('userSubscription');
  //this.$socket.client.on('userSubscription', (payload) => {console.log(payload)});
},

// server
socket.emit('userSubscription','Send this message to only those who subscribed');

plz show me how to handle this on server side because even though i write this.$socket.client.off('userSubscription');
it is still printing on console
