TypeScript Core Patterns

What problem does it solve?

This Skill addresses the complexities of modern TypeScript development by providing clear patterns for type safety, runtime validation, and optimal configuration, reducing common errors and improving code quality.

Core Features & Use Cases

• Type Safety: Enforces strict type checking with modern compiler options like noUncheckedIndexedAccess.
• Runtime Validation: Integrates with libraries like Zod for robust data validation at API boundaries.
• Modern Patterns: Demonstrates advanced TypeScript features such as const type parameters, the satisfies operator, and discriminated unions.
• Use Case: When building a new API endpoint, use this Skill's guidance to define Zod schemas for request and response bodies, ensuring type safety from the client to the server.

Quick Start

Use the TypeScript Core Patterns skill to set up a new project with the 2025 tsconfig baseline, enabling strict and noUncheckedIndexedAccess.
