Once you go to the grocery store and pick the 25 different libraries fundamental to your application, congratulations! You've created a completely new interaction between those sets of libraries and you get to debug those interactions instead of your own code for a portion of your time.

I've seen this with python flask REST environments where folks pull all these tiny pieces off the shelf and stitch them together. Meanwhile Django REST Framework has a mostly common baseline that you adopt and then diverge from as needed.

I am getting bit in the butt right now for using the ionic framework for building a multi-platform mobile app.

If I want to build a mobile app in JS, but not use a framework (ionic/cordova/react native), how do I proceed?

While I admit framework-driven cross platform mobile apps are bad, even native code is vulnerable to OS updates shifting the ground from underneath them.

How do you use a library in mobile app dev?
