SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

proto unifies and streamlines multi-language tool version management across projects, ensuring consistent environments and reducing drift.

Core Features & Use Cases

  • Unified version management for Node.js, npm, pnpm, yarn, Bun, Deno, Rust, Go, Python, and more via plugins
  • Pin tool versions in .prototools to enforce team-wide consistency
  • Install, run, and upgrade tools with a single CLI and multi-tool workflows

Quick Start

Install proto using the official installer and start by pinning and using a few tools. For example:

  • Install: bash <(curl -fsSL https://moonrepo.dev/install/proto.sh)
  • Pin a version: proto pin node 20.10.0
  • Install and run: proto install node && proto run node

Frequently Asked Questions about proto

FAQPage Schema
How do I manage multiple language tool versions across a monorepo?▼

Multi-language tool version management centralizes Node.js, Rust, Go, Python, and other toolchains in a single interface. proto pins versions in .prototools files, enforcing consistent environments across team projects and eliminating version drift without maintaining separate version files per language.

Can I pin and install tool versions without switching between CLI commands?▼

proto provides a unified CLI for version pinning, installation, and execution. Use proto pin to lock versions in .prototools, proto install to fetch tools, and proto run to execute them—all from one command interface across all supported languages.

What's the best way to standardize Node.js, npm, and Rust versions across team projects?▼

Standardizing multi-language toolchains requires a dotfile-based definition system and pluggable backend architecture. proto stores pinned versions in .prototools, making them version-controllable and shareable, so every developer runs identical tool versions without manual configuration.

Does proto work with JavaScript, Rust, Go, and Python in the same project?▼

proto supports JavaScript runtimes (Node.js, Bun, Deno) and package managers (npm, pnpm, yarn), plus Rust, Go, Python, and more through a plugin system. A single .prototools file pins versions for all languages, unifying multi-language toolchain management in monorepos.

How do I switch between different tool versions for specific workflows?▼

proto CLI commands install, run, and pin enable switching toolchains for multi-tool workflows. Pin versions in .prototools to enforce defaults, then run specific versions on demand, supporting rapid context-switching between language ecosystems without manual PATH manipulation.

What happens if team members use different versions of Node.js, Go, or Python?▼

Version drift causes inconsistent builds and environment-specific bugs. proto eliminates drift by enforcing pinned versions via .prototools, ensuring all team members run identical tool versions and reducing environment-related failures in development and CI pipelines.
