✨ Code Quality

Problem

The condition if (port) treats port 0 as falsy, causing it to bypass port validation and call getFreePort() instead. Port 0 is a valid network port (meaning 'any available port'), but this logic incorrectly treats it as 'no port specified'. Users explicitly configuring port 0 will get unexpected behavior.

Severity: medium
File: src/configuration/utils.ts

Solution

Change condition to if (port !== undefined && port !== null) or if (typeof port === 'number' && port > 0) depending on intended behavior for port 0.

Changes

  • src/configuration/utils.ts (modified)
