Re-frame Flow

re-frame-flow is a graph based visualization tool for re-frame event chains. Let's assume we clicked a login button and triggered a series of events. login-fx -> http-fx -> some-fx -> some-db-handler ... (event after event), so a path gets generated, re-frame-flow visualizes all paths in a graph.

Installation

• Add re-frame-flow to dev dependencies:

:profiles
   {:dev
      {:dependencies [[org.clojars.ertucetin/re-frame-flow "X.Y.Z"]] }}

• Add re-frame-flow.preload to preloads:

{...
 :preloads [re-frame-flow.preload]
 ...}

Usage

• Make sure you have followed all of the installation instructions above.
• Start up your application.
• Once it is loaded, trigger some events (Flow panel gets updated when an event is triggered).
• Focus the document window and press ctrl-g to open the flow panel.

Dispatch tracking (Optional)

If you want to track the flow of dispatch and dispatch-sync, you need to use re-frame-flow's custom dispatch and dispatch-sync. ClojureScript does not provide *ns* at runtime, so these functions implemented as custom macros. Which means you can't pass around like they are functions.

• You need to move re-frame-flow dependency from dev to prod
• Update your dev closure-defines inside shadow-cljs.edn

  •   :dev
       {:compiler-options
        {:closure-defines
         {re-frame-flow.trace.dispatch-enabled? true}}}
    

• Update your views (or any namespace that uses dispatch)

  • (ns app.views
     (:require [re-frame-flow.macros :refer-macros [dispatch dispatch-sync]]
      ...))
