Switch to Redux?

[artlowel]

I think we should consider using Redux to manage the state in the new UI.

• What is it?
  • It is basically a set of design-patterns
  • The entire application state is kept in a single tree
  • This tree is immutable, if the state is changed a new tree is generated
  • There is a limited set of actions that define all the reasons why the state can be changed
  • Changing the state happens through reducers: functions take in an action, know what needs to be done in response to that action and return a new copy of the state tree
  • Other parts of the application can subscribe to a variable in the store to automatically update when it changes
• Why
  • easier to reason about
    • The store is the cannonical truth
  • easier to write tests for
  • faster: you can use the more efficient OnPush ChangeDetectionStrategy
  • components become a lot lighter as logic moves to reducers
  • It could allow us to continue on the client where the server left off, by initializing the client with the server's store.
