- Run
npm run dev (start vite dev server)
- Open site in browser
- Observe failure to import
roslib due to circular import in generated module
What is expected?
Running vite dev results in a functional JS module capable of being loaded by the browser.
What is actually happening?
The bundled module has a circular import that results in a failure to load the module. Reported error is:
undefined is not a function when attempting to call __CommonJSMin

Any additional comments?
Bug encountered when attempting to use roslib with latest vite. roslib has a dependency on eventemitter3 which has a ESM interface that exports an imports from a CJS file. This appears to be a trigger of this issue.
Using "overrides": {"rolldown": "1.0.0"} does not show the same behaviour.
Appears related to #9401 but as I understand it this repro does not use dynamic import or require (unless vite dev injects a dynamic import).
