      MFDoctor

      @tonoizer/mfdoctor is a post-build diagnostic tool for Module Federation projects. It finds configuration, sharing, manifest, runtime, and output problems while the build still has enough evidence to explain them.

      Register MFDoctor next to your federation plugin. Clean builds stay quiet; findings include a rule, impact, suggested fix, and a direct documentation link. Errors fail CI only after every finding has been collected.

      MFDoctor runs in Node after emit and adds nothing to the browser bundle. Start with Setup, CI, the rule catalog, and Limitations.
