Next.js 16 Audit

A Next.js 16 audit analyzes your TypeScript/TSX files across server components, client components, API routes, and utilities to identify deviations from best practices. It checks caching patterns, authentication implementation, data fetching, canonical type imports, and security compliance, then generates auto-fixes for each issue with exact code changes.

The audit validates 26 categories including server component usage, 'use cache' adoption over legacy cacheWrap, DAL-based authentication, repository patterns, Drizzle ORM usage, Zod validation, secure API route implementation, and canonical type imports across your codebase.

Yes, the audit generates auto-fix guidance with exact code changes for each finding. The report identifies deviations file-by-file and provides actionable remediation steps you can apply directly to your TypeScript and TSX files.

The audit operates on Next.js 16 projects with React 19 and a Clarity architecture. It requires TypeScript/TSX source files and works across your entire codebase without external dependencies, analyzing patterns in place.

The audit flags non-compliant patterns like legacy cacheWrap or non-DAL authentication as deviations from Next.js 16 best practices. It recommends migration paths—such as adopting 'use cache' and repository-based auth—with specific guidance for each file affected.

Yes, the file-by-file audit assesses server components, client components, API routes, and utilities in a single pass, applying context-aware rules to each type and flagging pattern violations specific to component boundaries and data-fetching scope.
