ZX is a TypeScript-based utility library and CLI tool designed for writing scripts that interact with the shell and manage processes. It provides a modular API for executing commands, handling interactive prompts, and managing temporary files, alongside utilities for HTTP requests and background processes. The system supports cross-platform execution across Node.js, Deno, and Bun, with comprehensive testing and pre-compiled artifacts for direct installation.

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 2 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 00a2c484e2 — 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.
