Redux-Doghouse is an open-sourced library that allows developers to create Scoped Actions and corresponding Scoped Reducers, enabling the creation of reusable UI components with Redux logic. This pattern helps keep complicated pieces of UI code separate from one another, making it easier to split reducers and actions into modules by component rather than view and model code. The library provides a way to compose unique scopes onto each instance of a component's action creators and reducers, allowing instances to behave independently while still responding to actions at a higher level. It can be used in scenarios where multiple instances of the same Redux-enabled component need to coexist without conflicting with each other.
