What problem does it solve?

This Skill provides a consolidated guide to best practices and mandatory conventions for developing with Next.js 16.1.6+, ensuring consistency and efficiency in Arlis's Next.js architecture.

Core Features & Use Cases

  • Proxy (formerly Middleware): Defines standards for the new proxy.ts file for handling redirects, rewrites, headers, and CORS.
  • Server Actions: Placeholder for future standards related to Next.js 16 Server Actions.
  • React Compiler: Placeholder for patterns related to the React 19/Next.js 16 Compiler.
  • Use Case: Developers can refer to this Skill to understand how to implement routing logic, manage request headers, and configure CORS policies within the Next.js 16 framework.

Quick Start

Refer to the Next.js 16 Standards skill for guidance on implementing proxy functionality.

FAQPage Schema
How do I implement proxy middleware in Next.js 16 for routing and CORS?

Next.js 16 proxy implementation uses the new `proxy.ts` file to define standards for handling redirects, rewrites, request headers, and CORS policies, replacing the former middleware architecture.

What is the proxy.ts file in Next.js 16.1.6?

The `proxy.ts` file in Next.js 16.1.6+ is the new standard for handling middleware functionality, managing routing logic, manipulating headers, and configuring CORS within the framework's architecture.

How do I manipulate request headers using Next.js 16 proxy?

You manipulate request headers in Next.js 16 by implementing header manipulation logic within the `proxy.ts` file, following architectural patterns and best practices for efficient web development.

Does Next.js 16 still support middleware.ts for handling redirects and rewrites?

Next.js 16.1.6+ transitions from middleware to the `proxy.ts` file for handling redirects, rewrites, headers, and CORS, establishing new architectural patterns and mandatory conventions for development.

What are the best practices for Next.js 16 Server Actions and React Compiler?

Next.js 16 standards include placeholders for future Server Actions and React 19 Compiler patterns, currently focusing on proxy implementation for routing, header manipulation, and CORS configuration.
