Show HN: Nub – A Bun-like all-in-one toolkit for Node.js

Nub is an all-in-one Node.js toolkit written in Rust that provides a Bun-like developer experience on top of standard Node.js, offering features like native TypeScript support, JSX transpilation, automatic .env loading, and built-in package management—all without requiring a new runtime or vendor lock-in. It claims significant performance improvements (up to 24× faster for certain operations) and automatically provisions the correct Node.js version for projects based on configuration files like .node-version or package.json. The tool consolidates functionality from multiple separate tools like npm, pnpm, nvm, and tsx into a single command-line interface.
