Update to React 18 and review app structure #237
Description
Is your feature request related to a problem? Please describe.
The app is using React 16, but React version 18 is now available. Also, this is the first app we built using React, and have since learned more about how to structure things.
Describe the solution you'd like
- Update the app to React 18, and update the testing infrastructure at the same time.
- Look at the overall structure of the app, and possibly bringing it more in line with how DIMES is structured.
Additional context
It's probably best to combine this work with issue #238
