Basic Examples

Basic Emit and Response

The very first thing that needs to be done is configuring our sockets in Nuxt config. In this example, we'll use the socket IO server that is hosted on heroku:

io: {
  sockets: [{
    url: '' // IO server lives here

The IO server on heroku has been configured to support connections to the "/index" namespace. At that namespace, one of the events it listens for is "getMessage". It will respond with the message. In addition to responding with the message, before the server fully responds, it will emit an event "chatMessages", which we could listen for. That will be shown in the next example. But first, the simple stuff...

In this example, when the component first mounts, we create a socket instance, and connect to '/index' namespace. Since we only have one entry in nuxt.config, that will be used. We define a method getMessage to emit the event, and define messageRxd to be used for saving the response. In the example below, the getMessage method has been promisified, but it would still work find without it.

Try It!

data () {
  return {
    messageRxd: ''
mounted () {
  this.socket = this.$nuxtSocket({ channel: '/index' })
methods: {
  getMessage () {
    return new Promise((resolve) => {
      this.socket.emit('getMessage', { id: 'abc123' }, (resp) => {
        this.messageRxd = resp
