RootDirOutDirMapping

Musings about resolving between rootDir and outDir

When /dist and /src are understood to be overlaid because of src -> dist compiling /dist/ /src/

Loop over require.extensions /src/foo.js /src/foo.mjs /src/foo.cjs /src/foo.ts /src/foo.mts /src/foo.cts /src/foo/index.js /src/foo/index.mjs /src/foo/index.ts // Where do we check package.json main??

/dist/foo.js /dist/foo.ts

_resolveLookupPaths _findPath _resolveFilename

_findPath calls resolveExports calls packageExportsResolve, which is in the ESM loader

Is anything within packageExportsResolve hooked/modified by us? File extension swapping?

When resolver calls statSync('./dist/foo.js') and we intercept and discover './src/foo.ts' How to redirect? We need to rewrite whatever local variable is storing ./dist/foo.js
