Code Review

This pull request upgrades core-js by 90 minor versions, from 3.12.0 to 3.45.1. While this is an automated Snyk PR, likely for security fixes, such a large jump for a critical polyfill library carries a high risk of introducing breaking changes. My review comment on package.json details this risk, highlighting that the new core-js version is significantly newer than what the project's build tools are designed for, and recommends thorough testing.

Separately, I've noticed several other key dependencies like @ngrx/* and @angular/language-service are outdated and incompatible with your Angular 15 setup. I recommend addressing these in separate PRs to improve project stability.

angular-app/package.json

    "@ngrx/store-devtools": "^12.1.0",
    "bulma": "^0.9.2",
-    "core-js": "^3.6.4",
+    "core-js": "^3.45.1",


This is a very large version jump for core-js, spanning 90 minor versions. This carries a significant risk of introducing breaking changes or subtle regressions, as core-js minor versions can contain breaking changes.

Your project's @angular-devkit/[email protected] uses @babel/[email protected], which is built against core-js versions up to ~3.25.1. Upgrading to 3.45.1 is a significant leap beyond what your build tooling was tested with.

Due to the high risk, I strongly recommend thorough testing before merging:

Full regression testing of the application.

Cross-browser testing, especially on older browsers.

Verifying the build process for new warnings or errors.

Analyzing the final bundle size for unexpected increases.
