The singleportscanner module is an asynchronous JavaScript port scanner for Node.js.
Portscanner can check only a port, and return port status for 'open' or 'closed' statuses and connection info.
npm install singleportscanner
const singleportscanner = require("singleportscanner");
singleportscanner(80, "www.example.com")
.then((res) => {
console.log(res);
})
.catch((err) => console.log(err));
