route-handlers

This skill provides a robust framework for developers working with Next.js App Router to implement server-side API logic efficiently. It streamlines the creation of route handlers, ensuring adherence to the standard Web Request and Response API conventions. Whether you are building a simple REST API, implementing complex data streaming, or managing headers and cookies, this tool acts as an expert assistant for backend development within your frontend-heavy project.

• Full support for HTTP methods including GET, POST, PUT, PATCH, DELETE, HEAD, and OPTIONS.

• Automated configuration for route.ts file conventions within the app directory structure.

• Capability to handle dynamic URL parameters, query string parsing, and complex request body processing (JSON, FormData, Text).

• Advanced response handling features, such as setting custom headers, cookie management, and implementing secure redirects.

• Built-in support for streaming responses, including standard text streaming and complex AI/LLM integration patterns using ReadableStreams.

• Integrated CORS configuration templates to ensure secure cross-origin communication for your endpoints.

• Automated caching strategy management, including default static behavior and opt-out mechanisms using dynamic force or headers.

• Use this skill to initialize new API routes or refactor legacy API patterns into the modern App Router architecture.

• Perfect for developers handling authorization logic, database integrations, or third-party service hooks (e.g., AI model streaming) within Next.js.

• Input requirements include your desired HTTP endpoint path, target functionality (e.g., authentication check), and the intended HTTP method.

• The output is clean, production-ready TypeScript code following Next.js best practices, minimizing boilerplate and ensuring type safety with request contexts.

• Keep in mind that route handlers are executed on the server; ensure all database interactions or sensitive logic are contained within proper environment variables or server-side utility functions.
