Fix Next.js App Router useEffect data fetching anti-patterns by migrating data retrieval logic into Server Components, eliminating unnecessary client-side state, and enforcing correct component boundaries to prevent waterfall requests and improve performance.

Common Next.js App Router anti-patterns when migrating from the Pages Router include retaining legacy data fetching methods, misusing useEffect for client-side data synchronization, and drawing incorrect Server and Client component boundaries. Correcting these ensures proper rendering responsibilities and TypeScript adherence.

Review Next.js code for improper Server and Client component boundaries by identifying unnecessary client-side state and incorrect useEffect usage. Shift data fetching and static rendering responsibilities to Server Components to optimize performance and align with TypeScript best practices.

This Next.js code review approach requires adherence to TypeScript best practices to effectively identify and correct anti-patterns. Applying TypeScript ensures accurate detection of unnecessary client-side state and enforces correct rendering responsibilities within the App Router.

You should not use useEffect for state management in Next.js when the data can be fetched on the server or derived from URL parameters. Moving this logic to Server Components or optimizing component boundaries eliminates unnecessary client-side state and improves App Router performance.
