Robert, are there any adjustments to this pattern that are needed a month later? Perhaps you'd consider making this into a project starter repo...

I used these as a start for a project template of sorts. https://github.com/PEZ/deps-edn-figwheel

I sort of merged the Figwheel starter project and this gist. Planning to create a tutorial for absolute beginners. If I get the time for it.
