Remote Rendering: Shopify’s Take on Extensible UI - The host loads an extension and then renders it

host.js

// Host

import { createEndpoint } from "@remote-ui/rpc";
import { createRemoteReceiver } from "@remote-ui/core";

const endpoint = createEndpoint(new Worker("./sandbox.js"));
const receiver = createRemoteReceiver();

endpoint.call.load("https://somewhere.com/extension.js").then(() => 
  endpoint.call.render(receiver.receive, {
  	setTitle: (title) => document.title = title
  });
);
