Nub's TypeScript loader is now a standalone package that runs under stock node, alongside fixes across install, resolution, configuration, and nub compile.

Nub is an all-in-one toolkit for Node.js written in Rust. The nub command is flag-for-flag compatible with node, while adding full support for TypeScript, JSX, tsconfig.json, .env loading, and modern Web and ECMAScript APIs. It also includes a fast script runner (nub run), package runner (nubx), Node version manager (nub node), and pnpm-compatible package manager.

The loader as a standalone package

@nubjs/loader runs TypeScript, JSX, tsconfig paths, and data-format imports under plain Node, with no Nub binary involved — install it as a dev dependency and register it the way tsx and ts-node are registered:

npm install --save-dev @nubjs/loader
node --import @nubjs/loader app.ts

Every preload form Node accepts works:

node --import @nubjs/loader app.ts        # ESM hooks + CommonJS require() augmentation
node --require @nubjs/loader app.ts       # CommonJS delivery (Node 20.19+)
node --import @nubjs/loader/esm app.ts    # ESM hooks only

It also works anywhere a preload can be set rather than passed, such as NODE_OPTIONS="--import @nubjs/loader" vitest. The native transform rides eight platform packages as optionalDependencies, covering macOS, Linux (glibc and musl), and Windows on x64 and arm64. Source that runs under the loader also runs unchanged under tsx or ts-node, so adopting it is reversible. Documentation is at nubjs.com/docs/loader. (#810)

Install and update

PR	What changed
#819	A version refused by the no-downgrade trust policy backtracks to an older in-range version that still carries its trust evidence, instead of aborting the install.
#823	Neither `outdated` nor `update` reports or offers a version below the one already installed.
#811	Engine settings Nub never reads are no longer listed or written by the config commands.

Runtime

The web-storage flag is passed on the command line instead of through NODE_OPTIONS, which every descendant process inherits. The flag does not exist before Node 22.4, so a child running an older Node aborted at startup — reachable on a host in the Node 22.4–24 band running Electron 34 or earlier, which embeds Node 20.18.1. (#812)

Compile

nub compile finds the strip tool on Windows — the probe never matched llvm-strip.exe, so every Windows compile silently produced an artifact roughly 4 MB larger than it should be. (#827)
