ZIM Socket and the ZIM Socket Page has been updated to use Socket IO ES6 modules (4.7.5). This is good as it bypasses CORS, which also means we can test locally. And... we now just need one script tag:
import zim from "https://zimjs.org/cdn/zim_socket"; // only script needed
This will import the Socket IO, the ZIM socket helper module and the ZIM server urls.
The Updates at https://zimjs.com/updates.html and the Docs at https://zimjs.com/docs.html?item=socket have been updated.
