portscanner is a Node.js module that allows developers to easily check the status of TCP ports. It provides functions to determine if a port is open or closed on a specified host, useful for service discovery, testing network connectivity, and avoiding port conflicts during application development. With simple asynchronous methods, portscanner streamlines the process of validating port availability programmatically, reducing manual checks and improving automation workflows for network-dependent applications.
