[Dargon789]

Snyk has created this PR to fix 1 vulnerabilities in the yarn dependencies of this project.

Snyk changed the following file(s):

• packages/browser-eslint-rules/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.

Code Review

This pull request upgrades eslint from v7 to v9 to resolve a security vulnerability. While the security fix is important, this is a major version upgrade that introduces significant breaking changes. The other ESLint-related dependencies in packages/browser-eslint-rules/package.json are incompatible with ESLint v9 and must also be upgraded. Merging this change without addressing these incompatibilities will break your linting setup. I have left a critical comment detailing the necessary actions. Please also ensure to update the yarn.lock file after resolving dependency conflicts.

[gemini-code-assist]

Upgrading eslint to a new major version (^9.0.0) is a significant change that will likely break your current setup due to dependency incompatibilities. ESLint v9 introduced many breaking changes, including a new configuration system.

The other ESLint-related packages in this project are not compatible with ESLint v9 and must be upgraded simultaneously:

• @typescript-eslint/parser and @typescript-eslint/eslint-plugin: Version ^4.2.0 is for older ESLint versions. You'll need to upgrade them to ^7.0.0 or newer for ESLint v9 compatibility.
• eslint-plugin-vue: The next tag is likely outdated. You will need a version of this plugin that supports ESLint v9 (likely v10.x or a pre-release).
• vue-eslint-parser: Version 7.1.0 is incompatible. This also needs to be upgraded to a version compatible with ESLint v9.

Before merging, please update these dependencies to compatible versions, test your linting process thoroughly, and regenerate the yarn.lock file.
