IPFS.swarm.peers gives empty array

Help
1

I have a function like this:

`async getIpfsPeers() {
    const peers = await this.node.swarm.peers();
    console.log("List of connected peers: ", peers);
    return peers;
}`

It’s inside a class, the class factory function is creating the IPFS instance. Bootstrap list works.

This is the output:
List of connected peers: []

Why am I seeing empty array?

Are you doing this shortly after the instance is created? Is it possible that the node just hasn’t had a chance to connect to any peers yet?

Yes, that indeed helped. Thank you!

You’ll also need to make sure, you have the right peers or a certain amount connected, otherwise you’ll be connected but the intended party won’t be able to get your content or receive your messages.

In https://github.com/QuestNetwork/qDesk/blob/master/src/app/sign-in/sign-in.component.ts we have:

 while(!this.q.os.isReady()){
        console.log('SignIn: Waiting for Quest OS...');
        this.q.os.sendBootMessage('Waiting For Peers... '+this.end()+'s');
        await this.ui.delay(5000);
      }

which allows to make sure all the conditions critical to the successful execution of methods like swarm.peers() are met

If you’re running an IPFS node in the same process you can also listen for peer:connect events fired by libp2p’s connection manager:

const IPFS = require('ipfs')

const ipfs = await IPFS.create()

ipfs.libp2p.connectionManager.on('peer:connect', (peerId) => {
  console.info('peer:connect', peerId.toString())
})

If it’s a remote node accessed via the ipfs-http-client, you have to poll the ipfs.swarm.peers method:

const waitFor = require('p-wait-for')

await waitFor(async () => Boolean((await ipfs.swarm.peers()).length))
