title: How to build SPA Spring applications without template engines
body: <p>For the sake of curiosity trying to build an SPA react spring boot application omitting template engines such as jsp or thymeleaf since it's worth decoupling frontend and backend at least in some cases as far as I understand. Managed to write controllers returning raw json and failed to add controllers returning html template with react script like I succeded to do when thymeleaf was included in dependencies and all html/js/css files were in resources folder. Should I run additional node server returning text/html? Can you give me some sample projects.
  Basically I want an app with navbar with links /index /something1 /something2 etc and kinda separate SPA with common html headers footers.</p>
