Upon transitioning between router pages, an error message pops up saying "Vue Socket.io-Extended: this.$socket.$subscribe is not a

I have created a basic Vue application that is designed to connect to a NodeJS server using websockets.

My setup involves the use of socket.io-extended for handling the connections.

After following the documentation and implementing the websocket connection within a component, everything works fine when I refresh the page. However, I encounter an issue when navigating away from the websocket page using vue router and then returning back to it. The console displays the following error message:

vue.runtime.esm.js?2b0e:619 [Vue warn]: Error in mounted hook: "TypeError: this.$socket.$subscribe is not a function"

[More frames with various functions]

vue.runtime.esm.js?2b0e:1888 TypeError: this.$socket.$subscribe is not a function
    at VueComponent.mounted (Index.vue?b484:23)
    ... (more lines of similar information)

Answer №1

I have found success using this code snippet for the Dynamic Listener feature:

this.sockets.subscribe('EVENT_NAME', (data) => {
    this.msg = data.message;
});

this.sockets.unsubscribe('EVENT_NAME');
