What it does

Provides TypeScript best practices for type-first development, making illegal states unrepresentable, and runtime validation patterns

Overview

typescript-best-practices is a Claude Code skill that provides TypeScript patterns for type-first development. It enforces practices such as making illegal states unrepresentable, exhaustive handling of union types, and runtime validation, ensuring that TypeScript and JavaScript code is robust and type-safe.

Key Features

Type-first development: Encourages designing types before implementing logic, using the type system as a primary design tool to catch errors at compile time.
Making illegal states unrepresentable: Guides code structure so that invalid data configurations cannot be expressed through the type system, eliminating entire categories of bugs.
Exhaustive handling: Ensures all variants of union types and discriminated unions are handled, preventing missed cases that could cause runtime errors.
Runtime validation patterns: Provides patterns for validating data at runtime boundaries (API responses, user input) to bridge the gap between TypeScript's compile-time checks and real-world data.

Who is this for?

This skill is for TypeScript and JavaScript developers who want to write more robust, type-safe code by leveraging advanced TypeScript patterns. It is particularly useful for developers working on applications where data integrity is critical and who want Claude Code to consistently apply type-first principles when reading or writing code.
