Socket.io-client: I want use ES6 import in browser side js

I would like to add that the following on the README.md

<script src="/socket.io/socket.io.js"></script>
<script>
  var socket = io('http://localhost');
  socket.on('connect', function(){});
  socket.on('event', function(data){});
  socket.on('disconnect', function(){});
</script>

// with ES6 import
import io from 'socket.io-client';

const socket = io('http://localhost');

Is misleading since it makes it look like you can use ES6 import on the client-side. Which you can't.

I was fooled as well. I do not always want to use webpack or similar.

ES6 imports are nothing new any more. Please make it work!

Many projects have a dedicated *.module.js which can be imported!

just adding on that .mjs is the preferred file type for ES6 modules.
