When using Redux Thunk in a React Native project, you can organize your code using a folder structure that separates concerns and follows best practices. Here's an example of a common folder structure for a React Native project with Redux Thunk:

- src
  - actions
    - types.js
    - authActions.js
    - cartActions.js
      ...
  - reducers
    - index.js
    - authReducer.js
    - cartReducer.js
      ...
  - middleware
    - thunk.js
  - store
    - configureStore.js
  - components
    - screens
      - HomeScreen.js
      - ProfileScreen.js
        ...
    - components
      - Button.js
      - Input.js
        ...
        ...
  - services
    - api.js
    - authService.js
      ...
  - utils
    - helpers.js
    - validation.js
      ...
  - navigation
    - AppNavigator.js
    - NavigationService.js
      ...
  - assets
    - images
      - logo.png
      - background.jpg
    - fonts
      - Roboto-Regular.ttf
      - OpenSans-Bold.ttf
    ...

Explanation of the folder structure:

actions:

• Contains action files that define the different types of actions and action creators for your app. For example, authActions.js can contain actions related to user authentication, while cartActions.js can handle actions related to the shopping cart.

reducers:

• Holds the reducers for the different parts of your app's state. The index.js file combines all the reducers into a single root reducer.

middleware:

• Contains middleware files, such as thunk.js, where you can set up and configure Redux Thunk middleware.

Store:

• Houses the configureStore.js file, where you can create and configure your Redux store.

components:

• Contains the reusable components and screens of your app. The screens directory can hold individual screen components like HomeScreen.js and ProfileScreen.js, while the components directory can hold reusable UI components like buttons, inputs, etc. services: Contains files for services, such as API service (api.js) and authentication service (authService.js), which handle the communication with external APIs or services.

utils:

• Contains utility files that provide helper functions and reusable code snippets, such as helpers.js and validation.js.

navigation:

• Holds files related to app navigation, including the main AppNavigator.js file that defines the navigation structure, and NavigationService.js, which provides a centralized way to navigate between screens.

assets:

• Contains static assets like images and fonts that are used in your app. This folder structure is just an example, and you can modify it based on the specific needs of your project. It's important to keep your code organized and follow best practices to ensure scalability and maintainability.

Conclusion

• In summary, the folder structure outlined above provides a well-organized approach to developing React Native applications. The actions directory holds action files that define different types of actions and their creators, allowing for a modular approach to managing app actions. The reducers directory houses reducers for different parts of the app's state, with the index.js file combining them into a single root reducer.

• The middleware directory contains middleware files, such as thunk.js, for setting up Redux Thunk middleware. The store directory is responsible for creating and configuring the Redux store. The components directory contains reusable components and screens, organized into screens and components subdirectories.

• The services directory handles external API communication, while the utils directory provides utility functions and code snippets. The navigation directory handles app navigation, and the assets directory stores static assets like images and fonts. Overall, this folder structure promotes code maintainability, modularity, and scalability in React Native development.
