## Debugging Reactive Expressions
Reactive expressions can be hard to debug. Something should be getting invalidated that isn't or it seems like something is getting updated too often.
Reactive expressions can be hard to debug - sometimes we notice that something should be getting invalidated that isn't or it seems like something is getting updated too often.
The `rx-debug` macro can be placed around the initialization of any `rx`:
```clojure
(rx-debug (rx (str @n)))
```
and you should seeing verbose debug statements corresponding to the:
* start of capturing dependencies
and you should seeing verbose debug statements corresponding to:
* start of dependency capture
* each dependency capture
* each invalidation event with a print out of watches
* each invalidation event with a print out of watch keys (note: not all watches aware of this `rx` will be registered - part of freactive's optimizations are smart attaching and removing of watches based on dirty flags)
