Stevey's Google Platforms Rant

I was at Amazon for about six and a half years, and now I've been at Google for that long. One thing that struck me immediately about the two companies -- an impression that has been reinforced almost daily -- is that Amazon does everything wrong, and Google does everything right.

Single-page Application Project Structure

..with .NET / F# (or Node.js / Express), AngularJS (or Facebook React + RxJS), TypeScript, Gulp.js (or Grunt), NuGet...

Goals

Project structure should reflect application's logic (as opposed to regular MVC apps which all look the same)
Group assets by feature rather than by type (including views, scripts, documentation, tests etc.)
Allow developers to edit client-side and server-side code independently from each other

Update 25 April 2020:

Many thanks to @KZL1992 @tomslominski @ptrofi @n-thumann for recent comments on their experiences with 20.04 and Parallels 13/14/15, especially the subsitution of the latest prl-tools-lin.iso for older Parallels to get it going.
