Nub

The all-in-one JavaScript toolkit that augments Node.js instead of trying to replace it.

A TypeScript-first toolchain for Node.js. Run TypeScript files, package.json scripts, and local CLIs on the node and package manager you already have. No new runtime, no lock-in.

It augments stock Node with some of Bun/Deno's best features:

• Full TypeScript support, including enum, namespace
• TypeScript-friendly resolution: extensionless imports, tsconfig.json#paths
• JSX / TSX
• Decorators and emitDecoratorMetadata
• Modern syntax like using (downleveled in transpiler when needed)
• Automatic .env* loading — Next.js/Vite parity
• Built-in loaders for common data formats — .yaml, .toml, .jsonc, .json5, .txt
• Polyfills for Temporal, Worker, URLPattern (when needed)
• Unflags experimental features like node:sqlite, vm.Module, localStorage, WebSocket, EventSource
• 2.9× faster startup than tsx
