colinhacks/zod

This system is a comprehensive validation and type-checking library for JavaScript and TypeScript, supporting both legacy (v3) and modern (v4) API paradigms. It provides a modular architecture with distinct entry points for full-featured and lightweight ('mini') usage, enabling efficient tree-shaking and smaller bundle sizes. The codebase includes extensive tooling for performance benchmarking, internationalization (i18n) for error messages, and rigorous testing across multiple TypeScript configurations to ensure type safety and compatibility.

About this page

  • The description of this project is derived from its own commit history, not from its README.
  • The score is its highest published measurement, taken on 3 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit 912f0f51b0 — the exact code this score is about.
  • Scored under rubric rubric-2026.08.18. Score the same commit under that rubric and you get the same number.
