subnet-discover

subnet-discover is a nodejs class that allows you to discover of specific devices in your local network. It's just an extension of a ping-subnet package. It has the same API with a small addition. At this moment it supports the only printers.

Installation

1npm install subnet-discover

Usage

You can specify the custom ranges parameter

Ranges parameter is represented by array of strings. There are two possible forms: just a single IP or the range.

1const SubnetDiscoverer = require('subnet-discover');
2
3const ranges = [
4  '192.168.0.123',
5  '192.168.0.1-192.168.0.100'
6];
7
8const subnetDiscoverer = new SubnetDiscoverer(ranges);
9
10subnetDiscoverer.on('host:printer', (ip, deviceName) => {
11  console.log('printer', ip, deviceName);
12});
13
14subnetDiscoverer.discover();

If the custom ranges is not specified it would be assigned using current network settings

1const SubnetDiscoverer = require('subnet-discover');
2
3const subnetDiscoverer = new SubnetDiscoverer();
4
5subnetDiscoverer.on('host:printer', (ip, deviceName) => {
6  console.log('printer', ip, deviceName);
7});
8
9subnetDiscoverer.discover();
