N4JS transpiles to V8-compatible ECMAScript code, using features available as of Node.js version 5. The transpiled modules can be used with System.js or Common.js module loader.
We have an extensive test suite (>90.000 tests) to ensure a stable nightly build. The current version is 0.3 and we like to call it a "public alpha" release. This does not mean that N4JS and its IDE are unstable, but you should expect bugs (becoming less every day) and missing features. We encourage you to give us feedback! You can ask questions using our mailing list. Or you can create bug reports and feature requests using Github issues. Before writing issues, please read our release notes. Also note how the N4JS IDE provides support for writing bug reports.
Download the Eclipse-based N4JS IDE as a single bundle.
