Event Handler Tracing

This panel provides an interactive, explorative UI through which you can browse the form-by-form execution trace of the ClojureScript code in your event handlers. You can inspect the data produced by every ClojureScript form, while retaining overall context.

Here's what it would look like if you had it setup:

Setup

First, adjust your project.clj by following these instructions to add day8.re-frame/tracing to the :dev :dependencies.

Then, within the namespace of yours which contains the event handlers to be traced (perhaps called events.cljs):

  1. Add the following :require to the ns: [day8.re-frame.tracing :refer-macros [fn-traced]]
  2. When you register your event handler, use fn-traced instead of fn, like this:
(reg-event-db 
   :some-id
   (fn-traced [db event]   ;; <-- notice the use of `fn-traced` instead of `fn`
      ... code in here))

Can you improve this documentation? These fine people already did:
