I know that WordPress and $40 templates from templatemonster is a king now :)

But if you not CSS editor, but a real DEV. and want to build strong projects for Small Business clients with easy content managing. What stack would you Propose ?

I would try: Front-end -> React + TypeScript + Redux or Flux

REST <-> API

Backend -> Wordpress in role of Headless CMS with API points + MySQL DB

(Why WordPress - because php support is on every hosting, and not a fancy node.js or maybe I mistake )
