PubSub Not Working on Relayed Connections without Relay Subscription in about js-libp2p

Relayed connections are time/data limited which means they can be closed at any time so data-heavy protocols don't run over them by default.

This is normally overridable with a runOnTransientConnection option but it looks like GossipSub doesn't have one of these - this will add it: ChainSafe/js-libp2p-gossipsub#485

Once that's been merged & released you should be able to configure it as:

import { createLibp2p } from 'libp2p'
import { gossipsub } from '@libp2p/gossipsub'

const node = await createLibp2({
  // other config
  services: {
    pubsub: gossipsub({
      runOnTransientConnection: true
    })
  }
})

---

What's happening in your example is the pubsub message is being sent from node2 to the relay over the direct websocket connection, then from the relay to node1.

What you want is for the message to got from node2 to node1 over the relayed connection between them instead.

With the runOnTransientConnection option you can remove gossipsub from the relay entirely.

@chainsafe/[email protected] contains the fix for runOnTransientConnection - please try that and the suggestions on https://gist.github.com/vaibhavmuchandi/7cc3d28161ceff68de9bb036bf03a24d

This should resolve the issue, please re-open this issue if you're still having trouble getting it working.
