General
​When should I learn Redux?​
​When should I use Redux?​
​Can Redux only be used with React?​
​Do I need to have a particular build tool to use Redux?​
Reducers
​How do I share state between two reducers? Do I have to use combineReducers?​
​Do I have to use the switch statement to handle actions?​
Organizing State
​Do I have to put all my state into Redux? Should I ever use React's setState()?​
​Can I put functions, promises, or other non-serializable items in my store state?​
​How do I organize nested or duplicate data in my state?​
Store Setup
​Can or should I create multiple stores? Can I import my store directly, and use it in components myself?​
​Is it OK to have more than one middleware chain in my store enhancer? What is the difference between next and dispatch in a middleware function?​
​How do I subscribe to only a portion of the state? Can I get the dispatched action as part of the subscription?​
Actions
​Why should type be a string, or at least serializable? Why should my action types be constants?​
​Is there always a one-to-one mapping between reducers and actions?​
​How can I represent “side effects” such as AJAX calls? Why do we need things like “action creators”, “thunks”, and “middleware” to do async behavior?​
​Should I dispatch multiple actions in a row from one action creator?​
Immutable Data
​What are the benefits of Immutability?​
​Why is immutability required in Redux?​
​Do I have to use Immutable.JS?​
​What are the issues with using ES6 for immutable operations?​
Using Immutable.JS with Redux
​Why should I use an immutable-focused library such as Immutable.JS?​
​Why should I choose Immutable.JS as an immutable library?​
​What are the issues with using Immutable.JS?​
​Is Immutable.JS worth the effort?​
​What are some opinionated Best Practices for using Immutable.JS with Redux?​
Code Structure
​What should my file structure look like? How should I group my action creators and reducers in my project? Where should my selectors go?​
​How should I split my logic between reducers and action creators? Where should my “business logic” go?​
​Why should I use action creators?​
Performance
​How well does Redux “scale” in terms of performance and architecture?​
​Won't calling “all my reducers” for each action be slow?​
​Do I have to deep-clone my state in a reducer? Isn't copying my state going to be slow?​
​How can I reduce the number of store update events?​
​Will having “one state tree” cause memory problems? Will dispatching many actions take up memory?​
​Will caching remote data cause memory problems?​
Design Decisions
​Why doesn't Redux pass the state and action to subscribers?​
​Why doesn't Redux support using classes for actions and reducers?​
​Why does the middleware signature use currying?​
​Why does applyMiddleware use a closure for dispatch?​
​Why doesn't combineReducers include a third argument with the entire state when it calls each reducer?​
​Why doesn't mapDispatchToProps allow use of return values from getState() or mapStateToProps()?​
React Redux
​Why isn't my component re-rendering, or my mapStateToProps running?​
​Why is my component re-rendering too often?​
​How can I speed up my mapStateToProps?​
​Why don't I have this.props.dispatch available in my connected component?​
​Should I only connect my top component, or can I connect multiple components in my tree?​
Miscellaneous
​Are there any larger, “real” Redux projects?​
​How can I implement authentication in Redux?​
