mcavage / node-leader Goto Github PK

Hey,
The example confused me, so this is my attempt to make it more clear, is my clarification correct?
Thanks,
D

elect(opts, function(err, node) {
   if (node.leader) {
     console.log('Hooray! I am the leader!');
   } else {
+    // you are not the leader, but might be elected at some later time.
     node.on('leader', function() {
-      console.log('I got elected as the leader!');
+      console.log('Old leader is down, and I was just elected as the leader!');
     });
   }
 });

Note that the example will not run out of the box because /my/service/path may not yet exist.

npm install leader installs the following leader package

Is this package deprecated? Want to evaluate this package if possible.

This project looks awesome! I've been waiting / wanting to do something like this myself for quite a while in Node, but haven't had enough real experience with ZK to do it.

I'd love to see a real world example when the lib is up to it - say, a simple example to manage master promotion in Redis or something like that. Would that be doable?
