I used war and peace to explain to a CEO how wasteful a mobile API was; twelve distinct items of data to display but we sent JSON larger than war and peace.
The D in SOLID is for dependency INVERSION not injection.
Most dependency injection that I see in the wild completely misses this distinction. Inversion can promote good engineering practices, injection can be used to help with the inversion, but you don’t need to use it.
In my experience this is a superb way to rapidly create bad integrations with AWS.
Some of the simple things will be easy, everything else will be hard.
Also instead of supplying an SDK, Amplify will provide components that can seriously constrain lots of your UI architecture decisions.
For Javascript the old mobile SDK was much more usable.
Almost all of the AWS services have a sensible JSON API, I wish that AWS would just generate sensible SDK bindings for Swift, Javascript and Dart and stop all development on Amplify.
