Overview:

In this article, we explore how to synchronize data between different browser tabs in a Next.js application using Redux State Sync. The need for such synchronization arises in dynamic web apps, especially in scenarios like e-commerce where maintaining a consistent state across multiple tabs is crucial.

Tutorial Highlights:

1. Initialize Your Next.js App:

• Begin by creating a new Next.js project using the command npx create-next-app@latest.
• Customize your project by choosing options like TypeScript, ESLint, Tailwind CSS, and more.
• If you already have an existing Next.js project, proceed to the next step.

2. Add Redux Toolkit to Your Project:

• If you haven’t set up Redux yet, install it using npm install react-redux @reduxjs/toolkit.
• Integrate Redux-State-Sync and Redux-Persist:
• Install the necessary packages with npm install redux-state-sync redux-persist @types/redux-state-sync.
• These libraries help manage state synchronization across tabs and enable persistence.

3. Build a Counter App Skeleton:

• Create a basic skeleton for a counter app.
• Update the code in app/page.tsx to include a simple counter component.
• Remove default styling from app/global.css.

4. Counter Component and Buttons:

• Define a counter component (CounterComponent) that displays the current count.
• Implement buttons for incrementing and decrementing the counter.
• The goal is to demonstrate state synchronization across multiple tabs.

5. Testing the Sync:

• Open the app in multiple tabs and observe how the state remains consistent.
• When one tab modifies the counter, the change reflects in all other open tabs.

Conclusion:

By following this straightforward guide, you can easily achieve tab synchronization using Redux State Sync in your Next.js applications. Whether you’re building e-commerce platforms or other dynamic web apps, this approach ensures a seamless user experience across different browser tabs1.
