ipfs swarm peers --enc=json --identify

[lidel]

Peers screen in ipfs-webui could show the agent versions, and all supported protocols, but it is too expensive to do ipfs.id call for each peer – especially in browser.

We already have ipfs swarm peers --enc=json --streams opt-in flag which fills Streams field in JSON response for each peer, example:

{
      "Addr": "/ip4/97.70.169.114/udp/4001/quic",
      "Peer": "12D3KooWDqzNdf6Ctcm8Xp89x7MWcdSbCFwnXeNfNXHhBjpr9jx9",
      "Latency": "",
      "Muxer": "",
      "Direction": 0,
      "Streams": [
        {
          "Protocol": "/ipfs/kad/1.0.0"
        }
      ]
    }

Streams info is used for "Open Streams" column on the peers screen, but it only shows active streams, not all supported protocols and versions:

Proposed improvement

Support passing --identify which adds Identify values, could be the same struct as one returned by ipfs id (result of libp2p's identify protocol):

{
      "Addr": "/ip4/95.208.80.171/udp/4001/quic",
      "Peer": "12D3KooWNCogGjemMiMjZmDxyVcrjP3KW7VFdSPTTGousXEhczuq",

      "Muxer": "",
      "Direction": 0,
      "Streams": [
        {

        }
      ],
      "Identify": {

        ],

        ]
      }
    }

If we had ipfs swarm peers --enc=json --identify then we could unblock ipfs/ipfs-webui#2086 and show it on the Peers screen, and see which nodes is JS-IPFs, Iroh, Kubo, which one is docker/brave/desktop etc

Unsure if we are caching identify results, if not, we should start doing so, removing the need for executing identify protocol lookup for every peer every time ipfs swarm peers --enc=json --identify is called.

If anyone has bandwidth to do this, feel free to pick it up, and @lidel me for review.

@lidel can I pick this up? any tips on where to start?
