implement reducer logic => createSlice => output (dispatch function, reducer (i.e. todoReducer) )

todoReducer => ConfigureStore => store

store => provider in main App

useSelector : get state

studiofu

https://github.com/studiofu/react-redux-boilerplate-code.git

initial state + root reducer + middleware => create store => store

post reducer => combine reducer => root reducer

initial state + action (type, payload) => reducer function => resolve state

define action function: async dispatch => dispatch actions

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

1. Follow standard conventions.
2. Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
3. Boy scout rule. Leave the campground cleaner than you found it.
4. Always find root cause. Always look for the root cause of a problem.
