import { getNodeList, listen, Node, Action } from "@colyseus/discovery";

// listen for node additions and removals through Redis
listen((action: Action, node: Node) => {

  if (action === Action.ADD) {
    // a Node has been added into the cluster

  } else if (action == Action.REMOVE) {
    // a Node has been removed from the cluster
  }

  console.log(node);
  // => {"processId": "xxxxxxxxx", address: "x.x.x.x:yyyy"}
});

// Retrieve pre-existing nodes
getNodeList()
  .then((nodes) => {
    nodes.forEach((node) => {
      // This node is already in the cluster

      console.log(node);
      // => {"processId": "xxxxxxxxx", address: "x.x.x.x:yyyy"}
    });
  })
