KD is quickly becoming part of my regular workflow with Meteor. It’s really great.
In the past, understanding what was going on moment to moment meant some combination of Kadira, console.log() + debugger, and/or inspecting my websocket connection(s) for added and removed subscriptions, etc. While it certainly doesn’t replace (or attempt to replace) all those tools, I find it brings together some of the best parts of all of them.
In some ways it behaves like a remote console for your dev app, specialized for Meteor. I could imagine enhancements both small and large that would move it in this direction. A small one would be clearing the Kadira Debug screen by button, similar to ‘Clear Console’. A big one would be bi-directionality where you call methods and perform actions on your dev app from Kadira Debug, via remote DDP. Just some food for thought.
I definitely recommend giving this package a spin.
