To do so it checks the real path of the file, and will type strip it if it's not within node_modules.\n\nThis also works in pnpm workspaces, but breaks in `pnpm deploy`. [This repo demonstrates that behavior.](https://github.com/everett1992/pnpm-node-type-stripping)\n\nRead or run `repro.sh` steps to reproduce.\n\nThis difference between workspace and deploy structure\n```\nbin/node_modules/lib -\u003e ../../lib\nout/node_modules/lib -\u003e .pnpm/lib@file++++lib/node_modules/lib\n```\n\ncause this error in out/index.ts, but not bin/index.ts\n\n```\nError [ERR_UNSUPPORTED_NODE_MODULES_TYPE_STRIPPING]: Stripping types is currently unsupported for files under node_modules, for \"file:///out/node_modules/.pnpm/lib@file++++lib/node_modules/lib/index.ts\"\n```\n\nThis would also break in npm, pnpm and other dependency managers that use `install-links` or other steps that indirect the workspace dependencies into node_modules.\n\n\n### What is the feature you are proposing to solve the problem?\n\nEither remove the node_modules restriction, add more detection's for 'local node_modules' cases - such as private: true or a new marker, or establish export conditions for type stripping.\n\nI am okay with emitting `.js` and using it in my deployed app, but I want to use `.ts` in development, and I don't want dev tools to require possibly stale `.js` files.\n\nI think a reasonable solution is an export condition for 'type stripping not supported' that node would use to fallback to .js instead of erroring.\n\n```\n\"exports\": {\n  \"unsupportedTypeStripping\": \"out/index.js\",\n  \"default\": \"src/index.ts\",\n}\n```\n  \n\n### What alternatives have you considered?\n\n_No response_","author":{"url":"https://github.com/everett1992","@type":"Person","name":"everett1992"},"datePublished":"2026-02-12T20:18:30.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":7},"url":"https://github.com/61793/node/issues/61793"}
