TypeScript Patterns Standards

Standards for TypeScript type definitions, runtime validation with Zod, generics, and type safety patterns.

When to Use

Use these standards when:

• Defining types, interfaces, or type aliases
• Validating API responses or user input
• Creating generic functions or components
• Implementing state machines or reducers
• Writing type guards or utility types
• Ensuring type safety at runtime

Core Principles

Zero Tolerance for any

Never use any type. Use unknown with type guards or generics instead.
