Node's require never selects a package's react-native condition and cannot load an ES module whose sources say a bare require, so the extractor resolves that entry itself and translates such a file to CommonJS as it loads. Directories are walked with the filesystem's glob, negative numbers become AST through valueToNode, the swallowed load error is named under DEBUG, and the optimize fixture is its source again with the suite restoring it after each run.

@hanzogui/build
One package, built by the TypeScript compiler alone: tsgo, three passes.
hanzogui-build # ESM + declarations, CommonJS, native
hanzogui-build --skip-native # a package with nothing platform-specific
hanzogui-build --watch # the ESM emit, continuously
hanzogui-build clean # remove dist and types (clean:build is the same)
Every package ships its source and three emits. Three project files describe them, and the compiler reads exactly one answer per target:
| project | writes |
|---|---|
tsconfig.esm.json |
dist/esm/*.js and types/*.d.ts; the one pass that typechecks |
tsconfig.cjs.json |
dist/cjs/*.js, marked commonjs by its own package.json |
tsconfig.native.json |
dist/native/*.js |
Source names every relative import with its extension and the compiler rewrites
it on emit, so what lands in dist is loadable by Node as written. Nothing else
runs over the code.
A sibling answers for its file on one target and reaches no other emit:
x.cjs.ts takes x's name in the CommonJS output, x.native.ts in the native
one. A module that needs its own location says import.meta.url in here.ts
and __filename in here.cjs.ts, and everything else imports url from
./here.ts. The CommonJS output is parsed as a script afterwards; a file only a
module could load fails the build by name.
Each emit answers process.env.GUI_TARGET with its own literal, "web" or
"native", so a bundler folds the other platform away.
The exports map points at what the emits produce: types/x.d.ts,
dist/esm/x.js, dist/cjs/x.js, and dist/native/x.js where the package
builds native.
