SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill ensures consistent, modular, and maintainable TypeScript type and interface definitions within a Next.js application. It provides clear rules to prevent overly large or disorganized type files, improving code readability, collaboration, and overall project quality.

Core Features & Use Cases

  • Modular Type Definitions: Guides on separating types and interfaces into multiple, smaller files.
  • File Size Limits: Enforces a maximum of 50 lines of code per type file for better readability.
  • Use Case: When defining data structures for a new feature in a Next.js app, use this skill to ensure all TypeScript types are organized into modular files, adhering to the specified line limits.

Quick Start

Define the TypeScript types for a User object, ensuring modularity and adherence to the 50-line limit.

FAQPage Schema
How do I organize TypeScript types across multiple files in a Next.js app?

Organize TypeScript types by splitting them into separate, focused files within your src/types module. This modular structure keeps each file under 50 lines, improves readability, and makes interfaces easier to maintain and reuse across your Next.js components, pages, and API routes.

What's the best way to structure type definitions for Next.js data models?

Define TypeScript interfaces for your data models using a modular approach with strict file-length constraints. Create separate type files for distinct entities—User, Product, etc.—adhering to the 50-line limit to maintain clean exports and enforce consistent typing conventions across your Next.js application.

Do I need separate type files for each feature in Next.js?

Yes, separating types by feature into individual files prevents bloated type modules and maintains modularity. Each file should contain logically grouped interfaces and stay within the 50-line limit, making types easier to locate, test, and refactor as your Next.js app grows.

How can I enforce consistent TypeScript conventions across my Next.js project?

Use a standardized modular type structure with enforced file-size limits to maintain consistency. Define all interfaces in the src/types module following the 50-line-per-file rule, ensuring reusable, clean exports that align with TypeScript best practices and improve team collaboration.

Can I apply type modularity to Next.js API routes and pages?

Yes, the modular type approach applies across all Next.js contexts—components, pages, and API routes. By organizing shared types in the src/types module with strict file constraints, you gain consistent, reusable interfaces that reduce duplication and improve maintainability throughout your entire application.
