Mutating Data & Revalidation

In web development, data mutation means changing data on the server. This includes creating new data, updating existing records, or deleting data.

• Create: Adding a new user.
• Update: Changing a user's email.
• Delete: Removing an item from a list.

Most interactive web applications rely heavily on data mutation to provide dynamic experiences.

Next.js 15's Server Actions are perfect for handling data mutations. They allow you to run server-side code directly from your React components, making it simple to update your backend.

Instead of creating API routes for every data change, you can define these actions right where they're needed, keeping your code organized and efficient.
