My work flow for a new app is: 1. Use whatever back end framework I know 2. Use server side templates 3. Slap on Turbolinks (because it works super easily with any back end framework) 4. Sprinkle in JS as needed This results in very fast development, very fast page loads and no duplication of things like validations / schemas. The best part is you can use whatever you want on the back end too. I've followed this pattern successfully with Rails, Flask and Phoenix. Screw SPAs (for most document heavy web apps).
