Add hooks to API

[tstirrat15]

Opening this issue for tracking purposes.

Things I've figured out so far:

• The notion of a two-pass render is kind of strange the context of hooks. I'm doing my best to approximate it, but it may come at the expense of two setStates in the same cycle when it's in frontend-only mode.
• Hooks don't play nicely with the current way that tests are written. I'm going to rewrite the tests to use the React Testing Library.

@tstirrat15 thanks for taking this up man! I currently don't have the time to implement any new stuff so your help is really appreciated!
