Next.js 16 App Router uses a file-based routing system with Server Components as the default. Create a new Next.js project, configure your app directory with route files, and use server-first patterns to handle data fetching and authentication before rendering, reducing client-side JavaScript and improving performance.

Yes. Prisma integrates seamlessly with Next.js 16 Server Components and server actions for database operations. Define your schema, run migrations, and call Prisma queries directly in server actions or server components without exposing database logic to the client.

Use Vitest for unit and integration testing in Next.js 16 projects. Configure Vitest with TypeScript support, write tests for server actions and API routes with full type safety, and validate your strict TypeScript configuration catches type errors before runtime.

Tailwind CSS v4 integrates with Next.js 16 through your CSS imports and configuration. Install Tailwind v4, update your PostCSS config, and use utility classes in your components; it works with both Server Components and client components without additional setup.

Next.js 16 applications can be containerized with Docker using a Dockerfile that builds and runs your app. Use mise to manage Node.js versions and other development tool dependencies, ensuring consistent environments across development and production deployments.

Enforce strict TypeScript, validate inputs in server actions, use environment variables for secrets, and leverage Next.js security headers. Server Components keep sensitive logic server-side, reducing client-side exposure; combine this with Prisma's type-safe queries for end-to-end type coverage.
