Adds a new jiti/static export that statically imports babel.cjs instead of lazy-loading it via createRequire(import.meta.url).

Closes #417

This solves two use cases:

  • Bun compiled binaries: ensures babel.cjs gets bundled into the binary
  • Webpack/bundler compatibility: the lazy createRequire(import.meta.url) pattern breaks when bundlers rewrite import.meta.url to a hardcoded path. A static import lets bundlers resolve and include babel.cjs correctly.

Usage:

import { createJiti } from "jiti/static";

📝 Walkthrough

Walkthrough

A new static bootstrap module is added to lib/jiti-static.mjs that statically imports pre-bundled Babel and JITI runtimes, with a createJiti factory function that delegates to the core JITI runtime. Corresponding export entries are added to package.json.

Changes

Cohort / File(s) Summary
Static Bootstrap Module
lib/jiti-static.mjs		 New module that wires pre-bundled Babel transformer and JITI runtime, defines error handler and native import wrapper, exports createJiti factory function that defaults opts.transform to the bundled Babel transformer before delegating to _createJiti.
Package Exports
package.json		 Added new "./static" export entry pointing to lib/jiti-static.mjs with types at lib/jiti.d.mts; added corresponding "static" entry to typesVersions map for type resolution.

Poem

🐰 A static path through Bun we pave,
With Babel bundled, bundled and brave,
Pre-wired and ready, no runtime wait,
JITI static makes code load great!

Hi @pi0 , can we have a release for this please?

jiti going from 2.5.1 to 2.6.1 (e.g. from nuxt/kit, that comes with nuxt/test-utils) when running npm audit fix to fix vulnerabilities, bumps jiti thus makes running Nuxt break with the Cannot find module '../dist/babel.cjs' error.

(btw, I'm not using bun nor webpack, it's just default nuxt with vite and nuxi so not even sure if that new import will fix, since I can't change nuxt/kit way of import)
