Getting the peer multiaddr from IPFS Swarm peers

Help
1

I’m trying to decode the buffer stored in the addr key found in the output returned by the IPFS swarm peers function back to the original string. I tried to use the toString() method with all supported encodings, but the output I’m getting is not correctly decoded.

const swarm_peers = await node.swarm.peers(); 
console.log(swarm_peers['2']['addr']['buffer'].toString());

Below is a sample output of what I’m getting

6sgp-1.bootstrap.libp2p.io���" BD�38\

How do I correctly decode the buffer?

Tried base58/64?

Will check it out tomorrow. Going to sleep :sleeping: now :slight_smile:

Hey, yeah I tried base64, it too gave incorrect output. Base58 I think isn’t supported (check this - https://nodejs.org/api/buffer.html#buffer_buffers_and_character_encodings)

Hey!

The buffer is based on js-multiaddr. You can see the examples in the repo to play with the buffer.

Here how you can read it:

  const peerInfos = await ipfs.swarm.peers();
  console.log(peerInfos[2].addr.toString());

Oh great, works perfectly! Thanks a lot
