socket.io-client error in new vue-cli 3.0: global is not defined

[weixiao-huang]

I use vue-cli 3.0.0-alpha.7 to create a new default project as below:

Than I add socket.io-client by using

yarn add socket.io-client

and use it in App.vue as below:

<script>
import HelloWorld from './components/HelloWorld.vue'
import io from 'socket.io-client'

export default {
  name: 'app',
  components: {
    HelloWorld
  },
  created() {
    const socket = io('/home')
    socket.on('hello world', (hello) => {
      console.log('hello: ', hello)
    })
  },
}
</script>

However, I got an error about Uncaught ReferenceError: global is not defined

This seems not the bug of socket.io-client since I have no error in the project generated by legacy vue-cli 2.
