## What it is
Nub is an all-in-one Rust CLI toolkit for Node.js that runs TypeScript/JSX files, package.json scripts, and local CLIs on stock Node, plus a pnpm-compatible package installer and a Node version manager. It augments the existing Node binary via public extension surfaces rather than shipping a new runtime, replacing tsx, npm run, npx, and nvm with a single fast binary.

## Use cases
- run typescript files directly on node without a build step
- faster alternative to npm run and pnpm run
- replace npx for running local or remote CLIs
- install node dependencies faster than pnpm
- manage node versions without nvm or fnm
- watch and restart a node server on file changes
- replace tsx and ts-node with a faster typescript runner
- one tool to replace node npm npx and nvm

## When to choose
- you want Bun-like developer experience without leaving stock Node.js
- you want one binary replacing tsx, npm run, npx, and nvm
- your project uses pnpm, npm, yarn, or bun lockfiles and you want a faster installer that round-trips them
- you need full TypeScript support including enum, namespace, and decorators without a build step
- you want fast script and bin runners for CI or local development

## When to avoid
- you need a genuinely different JavaScript runtime with its own APIs like Bun or Deno
- you rely on legacy npm flags such as --unsafe-perm or --scripts-prepend-node-path
- you want a battle-tested tool with years of production hardening
- your workflow depends on tooling that patches or forks the Node binary itself
