# ncc-babel-bug-repro

This PR reproduces a bug with `@vercel/ncc` where it's unable to correctly trace external files when source files have been processed with Babel.

## Reproduction instructions

Run `yarn` to install `@vercel/ncc`.

Run `yarn build:working` and observe how `worker.js` is correctly copied to `dist-working/worker.js`:

```
