@MoOx Do you need redux? 1 @MoOx
@MoOx Redux is a predictable state container for JavaScript apps.
2
@MoOx 3 State UI Actions Reducer transformed into dispatches passed
to returns new
@MoOx - behave consistently - run in different environments (client,
server, and native) - are easy to test 4 Redux helps you write applications that
@MoOx - live code editing (hot reloading) - time traveling
debugger. 5 Redux provides a great developer experience
@MoOx - persist state (local storage) & boot from it
(CSR & SSR) - serialize actions & save/reuse those - easy undo/redo / time traveling - share business logic between apps 6 Redux allows you to
@MoOx (Not tied to React) 7
@MoOx 8 @MoOx Redux is nice, makes app structuring foreseeable,
forces developers to think about their model

@MoOx “Let’s use Redux everywhere” 12
@MoOx “Let’s use Redux for a form input” 13

@MoOx Be careful not to use redux for everything 16
https://github.com/final-form/react-final-form By the guy that did redux-form, but later
@MoOx Redux + redux-thunk 17 Need at least 3 or
4 files. Reusability--
@MoOx React Context API A Replacement for Redux? 18 https://blog.bitsrc.io/react-context-api-a-replacement-for-redux-6e20790492b3
@MoOx Redux uses context 19
@MoOx Think McFly, think! 20
@MoOx What is setState() again? 21
@MoOx 22
@MoOx 23
@MoOx setState() and passing props might be enough 24 (if
your store is at the top of your app, you can pass things down)
@MoOx setState() 25 Everything fits in a file. Reusability++

@MoOx “Should you do this to your stateful components? Probably
not. Not unless you have a plan to benefit from this additional indirection” 41 https://medium.com/@dan_abramov/you-might-not-need-redux-be46360cf367
@MoOx What redux does, ReasonReact and Elm do 42 Actions
are types, reducers are functions, state is immutable, but at the language level
@MoOx 43
@MoOx “done in collaboration with the ReactJS team” 44 https://reasonml.github.io/reason-react/blog/2017/09/01/reducers.html
@MoOx - Does my app need this? - Does my
team need this? - Does my product need this? @MoOx 45 Before adding Redux (and other fancy things)
@MoOx Do my users need this? 46
@MoOx Redux is nice But not required 47
@MoOx Use Redux when it’s necessary not before 48 Like
any other tool
@MoOx Let’s love Redux Let’s hate Redux 49
