chore: bump Backstage to 1.51.1 and migrate test tooling#66
Merged
Conversation
Backstage CLI 0.36 makes Jest a peer dependency and drops the bundled version, so tests, type-check and lint all broke. Add jest 30, jsdom 27, @jest/environment-jsdom-abstract and @types/jest as devDependencies, and extend transformIgnorePatterns for the rehype-raw chain pulled in by the newer core-components. Migrate msw 1 (EOL) to msw 2 to drop @mswjs/interceptors' vulnerable xmldom (5 high advisories) and stay compatible with Jest 30. catalog-react 3.0 and eslint-plugin 0.3 have no breaking changes affecting this plugin. Pin GitHub Actions to commit SHAs via pinact for supply-chain safety.
