Snyk has created this PR to fix 2 vulnerabilities in the yarn dependencies of this project.

Snyk changed the following file(s):

  • plugins/example-todo-list-backend/package.json

Note for zero-installs users

If you are using the Yarn feature zero-installs that was introduced in Yarn V2, note that this PR does not update the .yarn/cache/ directory meaning this code cannot be pulled and immediately developed on as one would expect for a zero-install project - you will need to run yarn to update the contents of the ./yarn/cache directory.
If you are not using zero-install you can ignore this as your flow should likely be unchanged.

⚠️ Warning
Failed to update the yarn.lock, please update manually before merging.

Walkthrough

This PR updates dependency management in the example-todo-list-backend plugin by transitioning from workspace protocol references to pinned versions for multiple Backstage packages. The changes include upgrading @backstage/backend-common to 0.24.1, @backstage/backend-plugin-api to 0.6.19, @backstage/errors to 0.1.1, and @backstage/plugin-auth-node to 0.6.0. Additionally, the express package is upgraded from ^4.17.1 to ^4.22.0, which addresses potential security vulnerabilities. This shift to explicit version pinning improves dependency stability and demonstrates specific API compatibility for the example plugin.

Code Review

This pull request, automatically generated by Snyk, aims to fix two security vulnerabilities by updating dependencies in plugins/example-todo-list-backend/package.json. While the intent is good, the proposed changes have critical issues that will likely break the project.

Specifically:

  • Several @backstage dependencies are changed from using local workspace versions (workspace:^) to pinned versions from the npm registry. This is an anti-pattern in a monorepo and will cause version inconsistencies and build failures. I've recommended reverting these changes and using Yarn's resolutions feature to address the transitive dependency vulnerability.
  • The express package is updated to version 4.22.0, which does not exist. This will cause dependency installation to fail.

Additionally, the PR description notes that yarn.lock was not updated, which needs to be done manually. Given these issues, the PR should not be merged as is. The dependency issues need to be addressed correctly.

critical

Replacing workspace:^ with pinned versions is an anti-pattern in a Yarn workspace monorepo. It will cause this package to use versions from the npm registry instead of the local packages, leading to version inconsistencies and potential build failures. Please revert to using workspace:^.

To address the underlying security vulnerability, consider using Yarn's resolutions feature in the root package.json to force a specific, secure version of the vulnerable transitive dependency across the entire workspace.

Replacing workspace:^ with pinned versions is an anti-pattern in a Yarn workspace monorepo. It will cause this package to use versions from the npm registry instead of the local packages, leading to version inconsistencies and potential build failures. For example, @backstage/errors is being pinned to 0.1.1, which appears to be a significant downgrade from the version in the workspace (1.2.1). Please revert to using workspace:^.

To address the underlying security vulnerability, consider using Yarn's resolutions feature in the root package.json.

The version 4.22.0 for express does not exist in the npm registry. The latest version in the 4.x line is 4.19.2. This will cause the dependency installation to fail. Please correct the version to a valid one that resolves the security vulnerability.
