When it comes to building complex applications with Redux Toolkit, proper code organization is crucial for maintainability and scalability. In this blog post, we will discuss some best practices for structuring your Redux Toolkit code to improve overall organization and make it easier to navigate and understand.

Feature-based Folder Structure

One widely adopted approach for structuring Redux Toolkit code is to organize it based on features or modules. Each feature/module represents a self-contained piece of functionality within your application. This approach promotes separation of concerns and makes it easier to locate and work with related code.

Here’s an example of how you can structure your Redux Toolkit code using a feature-based folder structure:

src/
  features/
    counter/
      counterSlice.js         # Redux Toolkit slice for counter feature
      counterActions.js       # Action creators for counter feature
      counterSelectors.js     # Selectors for counter feature
      counterComponent.js     # React component for counter feature
    todos/
      todosSlice.js           # Redux Toolkit slice for todos feature
      todosActions.js         # Action creators for todos feature
      todosSelectors.js       # Selectors for todos feature
      todosComponent.js       # React component for todos feature
  store/
    store.js                  # Configure Redux store

By grouping related code together under feature-specific folders, you can easily locate and work with the necessary Redux Toolkit slice, actions, selectors, and associated React components.

Common Slice Pattern

Redux Toolkit promotes the use of the “slice” pattern, which encapsulates the reducer, action creators, and selectors for a specific piece of state in a single file. Following this pattern helps to keep your code organized and minimizes the need to jump between multiple files when working on a particular feature/module.

Here’s an example of how a common slice file may look like:

// counterSlice.js
import { createSlice } from '@reduxjs/toolkit';

const counterSlice = createSlice({
  name: 'counter',
  initialState: 0,
  reducers: {
    increment(state) {
      state++;
    },
    decrement(state) {
      state--;
    }
  }
});

export const { increment, decrement } = counterSlice.actions;
export default counterSlice.reducer;

By defining all the relevant logic in a single file, you can easily locate, modify, and reason about the behavior of a specific feature/module.

Conclusion

By adopting a feature-based folder structure and leveraging the slice pattern, you can significantly improve the organization and maintainability of your Redux Toolkit code. This approach allows for better separation of concerns, easier navigation, and quicker development. Following these best practices will set you on the path to building scalable and maintainable applications with Redux Toolkit.
