This is an example of using the devtools outside of chrome/firefox/etc. In order to simulate the same network restrictions found in a plugin environment, the inspection target is within an iframe, and communication is done via .postMessage.

You have to run ./build.sh (or ./build.sh --watch) to be able to run this. Then open index.html.

Here's an overview of how things work:

• the devtools ui loads
• an iframe is created, and the global (__REACT_DEVTOOLS_GLOBAL_HOOK__) is setup.
• the inspection target script is added to the iframe (from /test/example/)
• the devtools backend is added to the iframe

And yes, you can use this to inspect the inspector :) but remember to enable file access for your browser's react-devtools extension.
