Bug: intercepting postMessage from ipfs-postmsg-proxy

[hazae41]

Using this module https://github.com/ipfs-shipyard/ipfs-postmsg-proxy
And following this tutorial https://github.com/ipfs-shipyard/ipfs-service-worker

Then doing
createProxyServer(() => node) from a service worker
const node = createProxyClient() from a website

Then using await node.id() from the website, IPFS Companion shows the permission request dialog and responds with the ID of IPFS-Companion

IPFS-Companion does this even if it is disabled

@hazae41 Thank you for reporting. Are you using Firefox or a Chromium-based browser?

Chrome

@hazae41 by default createProxyClient() will use the same communication channel as window.ipfs

If you want to talk to instance in Service Worker, you need to bind to navigator.serviceWorker as in this example:

node = createProxyClient({
  addListener: navigator.serviceWorker.addEventListener.bind(navigator.serviceWorker),
  removeListener: navigator.serviceWorker.removeEventListener.bind(navigator.serviceWorker),
  postMessage: (data) => navigator.serviceWorker.controller.postMessage(data)
})

Let me know if this helped.
