I have an Angular-based Ionic project. The issue is that every time I do changes / save, it recompiles 5-10 times before it settles. It is extremely time consuming for development. I believe it something wrong with my configuration in angular.json, but I just can't figure it out! I would like to only have to reload once on save / changes.

In the console, this repeatedly shows when it recompiles:

ionic as well as angular, being SPA, when saving they recompile everything to always show you the latest developed version. Some IDEs can block the autobuild on the settings, but if this doesn't cause you major annoyances I would leave the setting, otherwise you would have to remind yourself to rebuild.
