Re-ducks Todos Example

This project was bootstrapped with Create React App and is a translation of the Redux Todos example using the re-ducks modular approach.

Translation changes to note

tldr; watch your state shape!

Since the ducks and re-ducks approaches use the combineReducer Redux method more the state shape changes from the original Redux Todos example.

Redux Todos

state {
  todos: [],
  visibilityFilter: "SHOW_ALL"
}

Ducks/Re-ducks Todos

state {
  todosState {
    todos: [],
    visibilityFilter: "SHOW_ALL"
  }
}

This is due to the fact that /src/state/ducks/index.js exports all the reducers from the feature folders. This is where the name of each feature's state is given.

Because of this state shape change, the selectors given to the mapStateToProps method must be changed to access the correct level of the state. For example, in the VisibleTodoList container.

const mapStateToProps = state => ({
  todos: todosSelectors.getVisibleTodos(
    state.todosState.todos,
    state.todosState.visibilityFilter
  )
});
