Some of this hits home for me. I work on the WAY DEEP backend of one of these 'modern single page apps', so dont really care about the REST apis or UI/UX. I will say our actual website is a nightmare to use and I attribute a lot of it to (A) mgmt demanding bad UI/UX on short timeframes(B) front end folks having the power to write butt loads of JS code to achieve said goals with no thought to system wide architecture / integration. We have so much shit happening each time you click to a different part of webapp, we seem to have hit the messy phase of a codebase where you cant change one part of the site without breaking something else in a totally different section of the codebase. to be fair though, as with everything there are pros and cons. Once i learned to deal with some of complexities and crazy UI/UX, using our web app is like driving a spaceship and it does work pretty fast considering all the data getting lifted, html getting rendered etc.
