How I structure Redux Toolkit in Next.js projects

In my Next.js projects, I prefer keeping reusable portfolio or application data in a central Redux Toolkit slice. This makes the UI cleaner because pages and components read from one predictable data source instead of repeating the same arrays everywhere.

For a portfolio website, Redux Toolkit can manage profile data, project filters, selected project state, gallery items, blog cards and contact links. The components stay focused on presentation while the slice handles shared state and actions.

This structure also makes future updates easier. When I add a new project, skill or social link, I update the data once and the homepage, footer, contact page and dedicated sections can reuse it instantly.

My goal is to build applications that are clean, maintainable and easy for another developer to understand. Good state management is one of the habits that helps achieve that.
