First Redux Application

First Redux Application Overview

At its core, first redux application is about doing one thing well in Redux. Once you understand the pattern, you can apply it consistently across projects and teams.

Good first redux application 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.

First Redux Application Example

const slice = createSlice({ name, initialState, reducers });
const store = configureStore({ reducer: { key: slice.reducer } });
// dispatch(slice.actions.something())

• Start from a minimal First Redux Application example and grow it only as needed.
• Keep things explicit so First Redux Application behaves the same for everyone on the team.
• Name things clearly so teammates understand your First Redux Application at a glance.
• Verify First Redux Application works as expected before relying on it in important work.

How First Redux Application Works in Redux

First Redux Application 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 First Redux Application

In modern apps, first redux application should use Redux Toolkit rather than hand-written Redux. Keep state minimal, colocate logic in slices, and use RTK Query for server data.
