The article discusses the implementation of the entities store unit in frontend applications within the Clean Architecture.
The entities store holds enterprise and application business entities along with their states and can be implemented using various libraries like React useState, useReducer, Redux, Mobx, Zustand, etc.
There are two types of implementation: inline and extracted stores, which can further be split into domain and presentation stores for managing different types of entities.
Testing the entities store can be done in integration with other units or in isolation based on guidelines from the store library developer, and it is recommended to split enterprise and application business entities as the store grows.
