detect-port-alt is a Node.js package designed to find an available port. Specify a desired port, and it intelligently probes for an open port, returning the next available sequential port if the original is occupied. Useful for applications requiring dynamic port allocation, such as development servers or testing environments, this package simplifies the process of avoiding port conflicts, ensuring smooth operation and consistent results across different machines. It offers a lightweight and reliable solution for developers needing to identify free ports programmatically.
