SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Standardizes TypeScript usage to reduce runtime errors and improve maintainability by enforcing strict typing, interface-first design, and safe patterns across a codebase.

Core Features & Use Cases

Enforces explicit typing and strict mode across the project to prevent implicit any and runtime surprises.
Prefers interfaces over type aliases, avoids enums, and promotes const assertions for safer, more maintainable types.
Integrates runtime validation with Zod and provides type guards to ensure data conforms to expected shapes in both frontend and backend contexts.

Quick Start

Audit a module and replace implicit any with explicit types, enable strict mode, and convert enums to const objects.

FAQPage Schema

How do I enforce strict TypeScript typing to eliminate runtime errors?▼

Enforce strict TypeScript typing by enabling strict mode, replacing implicit any with explicit types, and applying interface-first design to prevent runtime errors. This standardizes codebase safety and improves maintainability across frontend and backend modules.

Why should I prefer TypeScript interfaces over type aliases and avoid enums?▼

Prefer TypeScript interfaces over type aliases to enforce interface-first design, and avoid enums by converting them to const objects with const assertions. This approach ensures safer, more maintainable types across your codebase.

What's the best way to add runtime validation to TypeScript interfaces?▼

Add runtime validation to TypeScript interfaces by integrating Zod to ensure data conforms to expected shapes. Use type guards alongside Zod schemas to validate data structures dynamically in both frontend and backend contexts.

Does strict TypeScript typing work for both frontend and backend modules?▼

Strict TypeScript typing works for both frontend and backend modules, covering components, services, and shared utilities. It applies design-time checks, type guards, const assertions, and utility types uniformly across the entire codebase.

How do I audit an existing TypeScript module for strict type safety?▼

Audit a TypeScript module for type safety by replacing implicit any with explicit types, enabling strict mode, and converting enums to const objects. Apply type guards and utility types to enforce safe patterns and interface-first design.
