When i use ipfs-js i use him like that - 
`
    const ipfsInstance = new IPFS({
      repo: pathToIpfsRepo,
      EXPERIMENTAL: {
        pubsub: true
      },
      config: {
        Addresses: {
          Swarm: [
            "/ip4/0.0.0.0/tcp/6001",
            "/dns4/ws-star.discovery.libp2p.io/tcp/443/wss/p2p-websocket-star"
          ]
        }    
      },
      EXPERIMENTAL: {
        pubsub: true,
        dht: true
      }
    });
`
