is-port-reachable
Advanced tools
Package description
The is-port-reachable npm package is used to check if a port is reachable on a given host. It is useful for network diagnostics and monitoring, allowing developers to programmatically verify if services are accessible over the network.
Check port reachability
This feature allows you to check if a specific port on a host is reachable. The function returns a boolean indicating whether the port is open or not.
const isPortReachable = require('is-port-reachable');
(async () => {
const reachable = await isPortReachable(80, {host: 'example.com'});
console.log(reachable); // true or false
})();The portscanner package is similar to is-port-reachable and provides more comprehensive functionality for scanning ports, including checking a range of ports and providing detailed status for each port.
tcp-ping allows you to perform TCP pings to a server, which includes checking if a port is open. It provides additional information such as latency measurements, which is-port-reachable does not offer.
wait-for-port is another package that can be used to wait for a port on a host to become available. It is useful for scenarios where you need to wait for a service to start up before performing actions that depend on that service.
