I tried it and ran into many issues. For example:
- Incompatibility of transpiled artifacts with the Node runtime (many bugs were fixed, but I haven't tried again). I don't trust bun as a runtime.
- Broken monorepo support.
- No direct react support; you still need react-scripts/webpack/whatever. They have documentation on transpiling react, but it isn't the same.
- No type checking, as with many other tools.
Also, filter their issue tracker for bugs: https://github.com/oven-sh/bun/issues?q=is%3Aissue+is%3Aopen...
