Run them to see the exact rule IDs mfdoctor reports one fixture at a time: ```bash vp run demo:showcase ``` For **per-bundler build+mfdoctor** demos (Vite / Webpack / Rspack / Rsbuild, plus a partial Modern.js stub), see [standalone findings](https://mfdoctor.kevinbeier.com/de/standalone-findings.md) (`vp run demo:standalone`). Prefer fixtures where a missing or weak config would still reach a Module Federation plugin or build. Hard plugin failures (for example an empty `name`) stay as rules, not showcases. ## Config | Setup | Command | Finding | | -------------------------- | ------------------------------------------------------------------------------------------- | ------------------------------------------------- | | Expose key without `./` | `node dist/cli.js check examples/showcase/config/expose-key-invalid --ci` | `config/expose-key-invalid` (error) | | Missing expose path | `node dist/cli.js check examples/showcase/config/expose-path-missing --ci` | `config/expose-path-missing` (error) | | Invalid remote entry | `node dist/cli.js check examples/showcase/config/remote-entry-invalid --ci` | `config/remote-entry-invalid` (error) | | Invalid filename | `node dist/cli.js check examples/showcase/config/filename-invalid --ci` | `config/filename-invalid` (error) | | Hashed remote filename | `node dist/cli.js check examples/showcase/config/hashed-remote-filename --ci` | `config/hashed-remote-filename` (warning) | | Undeclared share scope | `node dist/cli.js check examples/showcase/config/share-scope-undeclared --ci` | `config/share-scope-undeclared` (error) | | Insecure remote HTTP | `node dist/cli.js check examples/showcase/config/remote-http-insecure --ci` | `config/remote-http-insecure` (warning) | | Local implementation | `node dist/cli.js check examples/showcase/config/implementation-local --ci` | no findings (heuristic does not fire) | | Suspicious impl muted | `node dist/cli.js check examples/showcase/config/implementation-suspicious-suppressed --ci` | no findings (`"off"`) | | Localhost remotes in CI | `node dist/cli.js check examples/showcase/config/remote-localhost-in-production --ci` | `config/remote-localhost-in-production` (warning) | | Alias prefix collision | `node dist/cli.js check examples/showcase/config/remote-alias-prefix-collision --ci` | `config/remote-alias-prefix-collision` (error) | | DTS outputDir mismatch | `node dist/cli.js check examples/showcase/config/dts-output-dir-mismatch --ci` | `config/dts-output-dir-mismatch` (warning) | | Alias overlapping shared | `node dist/cli.js check examples/showcase/config/alias-share-bypass --ci` | `config/alias-share-bypass` (warning) | | Nested producer DTS | `node dist/cli.js check examples/showcase/config/nested-producer-dts-extract --ci` | `config/nested-producer-dts-extract` (warning) | | Nested producer DTS ok | `node dist/cli.js check examples/showcase/config/nested-producer-dts-extract-ok --ci` | no findings (`extractRemoteTypes: true`) | | Direct `.js` remotes + DTS | `node dist/cli.js check examples/showcase/config/js-remote-without-type-urls --ci` | `config/js-remote-without-type-urls` (warning) | ##
