#Nodeup

Nodeup is a Rust-based Node.js version manager with predictable channel resolution, deterministic shell completions, and shim-based execution for node, npm, npx, yarn, and pnpm.

Use Nodeup when you want a single CLI that can install Node.js runtimes, select the active runtime by explicit command, directory override, or global default, and dispatch common Node.js executable names through managed shims.

#Start Here

• Install and verify Nodeup.
• Install a runtime and run a command.
• Read the complete command reference.
• Understand runtime resolution precedence.
• Use managed shims and package-manager dispatch.
• Integrate JSON output, colors, and logs.

#Supported Hosts

Nodeup runtime installation and shim dispatch target:

• macOS x64 and arm64
• Linux x64 and arm64
• Windows x64 and arm64

x86 hosts are outside the documented support scope.

#Runtime Selectors

Nodeup accepts exact Node.js versions with or without the v prefix, reserved channels, and linked runtime names:

nodeup toolchain install 22.1.0
nodeup toolchain install v22.1.0
nodeup default lts
nodeup default current
nodeup default latest
nodeup toolchain link work-node /opt/node-v22

Reserved channel selectors are exact and lowercase: lts, current, and latest.

#Validation Commands

Use these commands from the repository root when changing Nodeup documentation:

pnpm --filter nodeup-docs test
pnpm --filter nodeup-docs build
