node-zookeeper-explorer's Issues

New node and data modification fields to get focus when appearing on the screen.

Connections on the server side must be stored per connection host

So they're not created every time when user connects.

Modifications history

Would be nice to add the history and possibly undo?

Implement watchers for currently active node

Submit new node and data modification with keyboard.

Implement authentication

Allow modifications only when authenticated.

Implement background watchers with notifications

For nodes that aren't active. Notify user about the updates.

Implement top navigation

Make the tree auto expand to the given node.

Delete with children - exception

Delete with children is causing
Error: Can't set headers after they are sent.
at ServerResponse.OutgoingMessage.setHeader (http.js:689:11)

The recursive callback function "_$deregisterFromZooKeeper" is causing this issue.

Any proposal for fixing it ?

Thanks,
Manjiri

Creating new node for the root does not work.

An alert message is displayed instead.
Should create a node and reload the tree.

Implement node data modification.

Close ZK connections on inactivity

On the server side.

Zookeeper dependency broken on earlier versions.

Older versions of node-zookeeper cannot build the zookeeper library. This is because it attempts to retrieve the zookeeper c client version 3.4.3 for building. For whatever reason, that version of the C client no longer exists in Apache mirrors.
The maintainer of node-zookeeper has fixed this by publishing prereleases of zookeeper-3.4.6. However the fix is only available for [email protected]. Since it's infeasible to expect the node-zookeeper maintainer to retroactively patch all earlier versions, I think it'll be better to update node-zookeeper-explorer's dependency on node-zookeeper.
