In odoo11 community edition, I have a custom js inherit the point_of_sale.assets and I want to include the socketio library and use it inside this custom js file
<?xml version="1.0" encoding="utf-8"?>
<odoo>
<template id="assets" inherit_id="point_of_sale.assets">
<xpath expr="." position="inside">
<script type="text/javascript" src="/okmenu/static/src/js/custom.js"></script>
<script type="https://cdnjs.cloudflare.com/ajax/libs/socket.io/1.7.3/socket.io.js"></script>
</xpath>
</template>
</odoo>
