What is the best practice around choosing directory structure for the application in ionic? Can we choose directory structure similar to angular application which emphasize on grouping of files on the basis of feature & not by file type. I am asking this because I have seen a pattern in ionic apps which puts all js and html files separately i.e. in www/js and www/templates. Can I use different directory structure for my files as shown in image? Is it going to create trouble while building the app for different platforms?
