vue-socket.io app not receiving emit from express socket.io app - node.js

Question

I am trying to create a socket.io communication between an express app using socket.io (localhost:8000) and a vue app using vue-socket.io (localhost:8080). The express app is receiving emissions from the vue app but not vice versa. Here is my express app though I'm pretty sure the problem lies in the vue app:
Backend Express
const port = 8000
const express = require("express")
const socket = require("socket.io")
const app = express()
const server = app.listen(port, () => {
console.log(`App is lisening to port ${port}...`)
} )
const io = socket(server)
io.on("connection", (socket) => {
console.log("connected to " + socket.id) //this is successfully getting logged
socket.on("chat", (msg) => {
console.log(socket.id + ": " + msg) //this is successfully getting logged when I click send
io.sockets.emit("chat", msg)
} )
} )
I'm guessing the problem is somewhere below:
Frontend Vue (using CLI)
main.js:
import Vue from 'vue'
import App from './App.vue'
import VueSocketIO from 'vue-socket.io'
import SocketIO from 'socket.io-client'
Vue.use(new VueSocketIO( {
debug: true,
connection: SocketIO('http://localhost:8000')
} )
)
Vue.config.productionTip = false
new Vue({
render: h => h(App),
}).$mount('#app')
Chat component (Chat.vue)
<template lang="html">
<div>
<input type="text" v-model="input"/>
<button #click="send">Send</button>
</div>
</template>
<script>
export default {
sockets: {
//These dont work, nothing is printed to the console
connect: function () {
console.log('socket connected')
},
chat: function (msg) {
console.log("chat message recieved!: " + msg)
}
},
data(){
return {
input: ""
}
},
methods: {
send(){
this.$socket.emit('chat', this.input) //This works and is recieved by the express app!
}
}
}
</script>
I've been trying to figure this out for a day now with no luck.
Once again my only goal is to be able to receive emissions front the express app. As a side note if there is a better way to use socket.io in vue without using vue-socket.io I would be glad to investigate.

Answer 1

I was able to get this working simply by using vue-socket.io-extended instead of vue-socket.io. That was it, no major changes to the code necessary. I know technically this doesn't solve the issue using vue-socket.io, but until someone figures that out, I will leave this as the answer for future searchers.
