SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

TypeScript code often suffers from weak types, inconsistent interfaces, and fragile refactoring. This Skill provides a structured set of patterns and guidelines to enforce strict typing and maintainable contracts across projects.

Core Features & Use Cases

  • Const Types Pattern (REQUIRED): Create const objects first, then derive types to ensure runtime values and type safety.
  • Flat Interfaces (REQUIRED): Use one-level-deep interfaces with named inner types to keep definitions readable and reusable.
  • Never Use any: Prefer unknown and type guards to guarantee safer boundaries.
  • Utility Types: Use Pick, Omit, Partial, Required, Readonly, and other utilities to compose robust types.
  • Type Guards: Implement runtime checks to narrow types and validate input.
  • Import Types: Use import type for clean, dependency-safe type references.

Quick Start

Ask the AI to apply strict TypeScript patterns across the codebase by defining types, interfaces, and const objects where appropriate.

FAQPage Schema
How do I enforce strict TypeScript patterns across my codebase?

Enforce strict TypeScript patterns by requiring const-based types, flat interfaces, and avoiding any. This reduces runtime errors and increases maintainability across frontend, backend, and shared code.

What is the best way to structure TypeScript interfaces for maintainability?

The best way to structure TypeScript interfaces is to use flat, one-level-deep interfaces with named inner types. This keeps definitions readable and reusable while ensuring strong typing contracts across your project.

Why should I avoid any in TypeScript and what should I use instead?

You should avoid any in TypeScript to guarantee safer boundaries and prevent runtime errors. Prefer using unknown combined with type guards to implement runtime checks that narrow types and validate input securely.

How do I create runtime type guards to validate input in TypeScript?

Create runtime type guards in TypeScript by implementing checks that narrow types and validate input dynamically. This ensures safer boundaries by replacing any with unknown and verifying data shapes at runtime.

Does this strict typing approach work for both frontend and backend code?

Yes, this strict typing approach applies to frontend, backend, and shared code. Strong types, flat interfaces, and const patterns ensure consistent contracts and reduce runtime errors across your entire codebase.

When do I need to use import type for TypeScript type references?

Use import type in TypeScript when you need clean, dependency-safe type references. This separates type imports from value imports, ensuring that types do not impact runtime behavior and maintaining strict typing boundaries.
