TODO: WHY! https://flic.kr/p/9yaos5
React is Simple Give it an input, get an output
React does one thing and it does it well It has a small public API surface area
https://twitter.com/thomasfuchs/status/708675139253174273
React is Simple “React applications start complex but maintenance complexity
of React applications doesn’t grow much as your applications grow
Its declarative and predictable nature High level of transferable knowledge
Learn once, write everywhere
React shines with Redux
What is Redux? “Redux is a state management library for
JavaScript applications, inspired by Flux and Elm.
What is Redux? (in human English) “Kind of like event
sourcing and pub/sub, with a fancier name.
The Problem
Redux Store
The Meat of Redux Actions Reducers Store
The Meat of Redux Actions Actions describe updates
The Meat of Redux Reducers Reducers apply updates based on
actions
The Meat of Redux Store Store is where everything comes
together and it acts as the source of truth for the application state
Simple Example: Counter
React Usage (Manual Way)
Usage with React
The Whole Idea Data Down Actions Up http://www.samselikoff.com/blog/data-down-actions-up/
The Whole Idea You have one state, one state only
for your entire application! https://flic.kr/p/9QQHW
The Whole Idea You never mutate the state! https://flic.kr/p/pzf72v
But why Redux and not flux, mobx, marty? https://flic.kr/p/NzcYg
It boils down to scientific reasons https://flic.kr/p/byrtr Well... NO!
