Project Setup is an important part of working effectively with Redux. This lesson explains what project setup means, how it works, and how to apply it with practical examples you can reuse.
Project Setup Overview
At its core, project setup is about doing one thing well in Redux. Once you understand the pattern, you can apply it consistently across projects and teams.
Good project setup pays off across the whole project: fewer surprises, easier collaboration, and smoother onboarding. The snippet below is a solid starting point.
import { configureStore } from '@reduxjs/toolkit';
import counterReducer from './features/counter/counterSlice';
export const store = configureStore({
reducer: {
counter: counterReducer,
},
});
export type RootState = ReturnType<typeof store.getState>;
export type AppDispatch = typeof store.dispatch;
configureStore sets up the Redux store with good defaults, including Redux DevTools and thunk.
Start from a minimal Project Setup example and grow it only as needed.
Keep things explicit so Project Setup behaves the same for everyone on the team.
Name things clearly so teammates understand your Project Setup at a glance.
Verify Project Setup works as expected before relying on it in important work.

How Project Setup Works in Redux
Project Setup follows Redux's predictable data flow: components dispatch actions, reducers compute the next state from the previous state and the action, and subscribed components re-render.
configureStore sets up the Redux store with good defaults, including Redux DevTools and thunk.
State lives in a single, read-only store.
Actions are the only way to describe a change.
Reducers are pure functions that return the next state.
Redux Toolkit removes most boilerplate with slices and thunks.
Practical Guidance for Project Setup
In modern apps, project setup should use Redux Toolkit rather than hand-written Redux. Keep state minimal, colocate logic in slices, and use RTK Query for server data.
Concern
Recommendation
Boilerplate
Use Redux Toolkit (createSlice)
Server data
Prefer RTK Query over manual thunks
Performance
Memoize selectors with createSelector
Types
Use typed useAppSelector/useAppDispatch hooks
Common Mistakes
Copying project setup commands or snippets without understanding what each part does.
Skipping edge cases and error handling when using project setup.
Not verifying the result of project setup before moving on.
Over-complicating project setup before you actually need the extra flexibility.
Key Takeaways
Project Setup is a core part of working effectively with Redux.
Start small and keep project setup focused on a single goal.
Apply consistent patterns so project setup scales across your project.
Practise and document project setup to keep your workflow maintainable.
Pro Tip
Bookmark this project setup pattern and reuse it. Consistency across your Redux work is worth more than clever one-off solutions.
