An asynchronous port scanner for Node.js.
Browse cluster: Cluster 192 →The portscanner module is an asynchronous port scanner built for Node.js that can check individual ports or ranges of ports to determine whether they are open or closed. The library provides several functions for port scanning tasks, including checking a single port's status, finding the first available port in a range, and finding the first port in use, with support for both callback-based and promise-based interfaces. It is written in JavaScript and can be installed via npm.
