Code Review

This pull request, generated by Snyk, upgrades socket.io from version 4.6.1 to 4.8.3 to address security vulnerabilities. While the upgrade is necessary, it appears to be incomplete. The new version of socket.io has updated peer dependency requirements for projects using the Redis adapter, which are not addressed in this PR. I've added a comment highlighting the need to also upgrade the redis and @socket.io/redis-adapter packages to prevent potential runtime issues.

[gemini-code-assist]

While upgrading socket.io is important for security, this new version (>=4.7.0) has updated requirements when used with the Redis adapter.

According to the official socket.io v4.7.0 release notes, redis version 4.6.7 or newer is required. Your project currently uses ^4.0.2, which could lead to runtime failures.

To ensure compatibility and stability, I recommend also upgrading @socket.io/redis-adapter and redis in this PR. The latest versions are compatible with socket.io@4.8.3.

For example, you could update your dependencies to:

"@socket.io/redis-adapter": "^8.3.0",
"redis": "^4.6.7",
"socket.io": "^4.8.3"
