SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill codifies type-first development patterns to strengthen TypeScript projects.

Core Features & Use Cases

Enforces discriminated unions, branded types, and exhaustive checks to prevent invalid states.
Provides guidance on runtime validation with libraries like Zod across frontend and backend codebases.
Offers practical examples for React, Node, and library authors to improve reliability.

Quick Start

Enable strict mode in tsconfig.json and start by defining data models with interfaces and types before implementation. Then apply the patterns to refactor existing code and gradually introduce type-safety improvements.

FAQPage Schema

How do I enforce type-safety to prevent invalid states in TypeScript?▼

To enforce type-safety and prevent invalid states in TypeScript, apply type-first development patterns like discriminated unions, branded types, and exhaustive checks. These patterns restrict data models to valid configurations, reducing runtime errors and API drift.

How does runtime validation with Zod work across frontend and backend codebases?▼

Runtime validation with Zod works by parsing untrusted input against schema definitions to ensure data integrity. This type-first pattern enforces strict typing across frontend and backend codebases, preventing API drift and runtime errors before processing logic executes.

What is the best way to start type-first development in an existing React project?▼

The best way to start type-first development in a React project is to enable strict mode in tsconfig.json. Define data models with interfaces and types before implementation, then gradually refactor existing code to introduce type-safety improvements.

Do I need strict typing enabled to use discriminated unions and branded types?▼

Yes, strict typing in tsconfig.json is required to effectively use discriminated unions and branded types. Enabling strict mode ensures the compiler enforces exhaustive checks and prevents invalid states, which is necessary for robust type-first development.

Can I use these type-safe patterns for Node backend libraries?▼

Yes, you can use these type-safe patterns for Node backend libraries. The type-first development approach applies to both frontend and backend codebases, offering practical examples for library authors to improve reliability and enforce strict modular design.
