I'm a visual person so perhaps seeing some code will help. I've gutted a CRUD heavy side project that shows how I lay things out and put it on Github [1]. I left out the back end folder so this repo isn't intended to work. The "users" and "journals" folders are the CRUD parts.

I prefer a domain folder structure versus splitting things by function. So instead of folders like "actions/userActions.js" and "reducers/userReducer.js" I'll do "users/actions.js" and "users/reducers.js".

Ping me on github if you have any more questions.
