next-redux-wrapper

What is next-redux-wrapper?

The next-redux-wrapper package is a utility that helps integrate Redux with Next.js applications. It simplifies the process of setting up Redux in a Next.js environment by providing a higher-order component (HOC) that can wrap the Next.js App component, ensuring that the Redux store is properly initialized and available throughout the application.

What are next-redux-wrapper's main functionalities?

Store Initialization

This feature allows you to initialize a Redux store and wrap your Next.js application with it. The `createWrapper` function from next-redux-wrapper is used to create a wrapper that can be applied to the Next.js App component.

import { createStore } from 'redux';
import { createWrapper } from 'next-redux-wrapper';

const reducer = (state = { count: 0 }, action) => {
  switch (action.type) {
    case 'INCREMENT':
      return { ...state, count: state.count + 1 };
    default:
      return state;
  }
};

const makeStore = () => createStore(reducer);

export const wrapper = createWrapper(makeStore);

Server-Side Rendering (SSR) with Redux

This feature demonstrates how to use next-redux-wrapper to handle server-side rendering with Redux. The `getServerSideProps` function is wrapped with `wrapper.getServerSideProps`, allowing you to dispatch actions and access the Redux store on the server side.

import { wrapper } from '../store';

const Page = ({ count }) => (
  <div>
    <h1>Count: {count}</h1>
  </div>
);

export const getServerSideProps = wrapper.getServerSideProps((store) => async () => {
  store.dispatch({ type: 'INCREMENT' });
  return { props: { count: store.getState().count } };
});

export default Page;

Static Site Generation (SSG) with Redux

This feature shows how to use next-redux-wrapper for static site generation with Redux. The `getStaticProps` function is wrapped with `wrapper.getStaticProps`, enabling you to dispatch actions and access the Redux store during the build process.

import { wrapper } from '../store';

const Page = ({ count }) => (
  <div>
    <h1>Count: {count}</h1>
  </div>
);

export const getStaticProps = wrapper.getStaticProps((store) => async () => {
  store.dispatch({ type: 'INCREMENT' });
  return { props: { count: store.getState().count } };
});

export default Page;

Other packages similar to next-redux-wrapper

next-redux-saga

The next-redux-saga package integrates Redux-Saga with Next.js. It provides a similar HOC to wrap the Next.js App component, but it focuses on managing side effects using Redux-Saga. Compared to next-redux-wrapper, it adds the capability to handle complex asynchronous flows with sagas.

next-redux-cookie-wrapper

The next-redux-cookie-wrapper package extends next-redux-wrapper by adding support for persisting Redux state in cookies. This is useful for maintaining state across server and client in a Next.js application. It offers similar functionality to next-redux-wrapper but with added state persistence capabilities.
