A little demo of how you might implement custom App Developer Tools.

In this example, we're using custom DevTools to make it easy to enable/disable "feature toggles". Please note that the concept of App DevTools has WAY more applicability than just feature toggles.

Files to take a look at to learn how the feature toggles are implemented for this app:

• public/config.js
• public/index.html
• src/feature-toggles.js
• src/App.js

Once you understand how the feature toggles work, then check out how the dev tools are installed and how they allow you to interact with the feature toggles by opening src/index.js and files in src/dev-tools/.
