Find all devices connected to the local network using arp -a. This module also pings all possible ip's in the local network to build the arp table.

Installation

Npm

npm install local-devices

Example

// Using a transpiler
import find from 'local-devices'
// Without using a transpiler
const find = require('local-devices');

// Find all local network devices.
find().then(devices => {
  devices /*
  [
    { name: '?', ip: '192.168.0.10', mac: '...' },
    { name: '...', ip: '192.168.0.17', mac: '...' },
    { name: '...', ip: '192.168.0.21', mac: '...' },
    { name: '...', ip: '192.168.0.22', mac: '...' }
  ]
  */
})

// Find a single device by ip address.
find({ address: '192.168.0.10' }).then(device => {
  device /*
  {
    name: '?',
    ip: '192.168.0.10',
    mac: '...'
  }
  */
})

// Find all devices within 192.168.0.1 to 192.168.0.25 range
find({ address: '192.168.0.1-192.168.0.25' }).then(devices => {
    devices /*
    [
      { name: '?', ip: '192.168.0.10', mac: '...' },
      { name: '...', ip: '192.168.0.17', mac: '...' },

      { name: '...', ip: '192.168.0.22', mac: '...' }
    ]
    */
})

// Find all devices within /24 subnet range of 192.168.0.x
find({ address: '192.168.0.0/24' }).then(devices => {
    devices /*
    [
      { name: '?', ip: '192.168.0.10', mac: '...' },

      { name: '...', ip: '192.168.0.211', mac: '...' }
    ]
    */
})

// Find all devices without resolving host names (Uses 'arp -an') - this is more performant if hostnames are not needed 
// (This flag is ignored on Windows machines as 'arp -an' is not supported)
find({ skipNameResolution: true }).then(devices => {
    devices /*
    [
      { name: '?', ip: '192.168.0.10', mac: '...' },
      { name: '?', ip: '192.168.0.50', mac: '...' },

      { name: '?', ip: '192.168.0.211', mac: '...' }
    ]
    */
})

// Find all devices, specifying your own path for the `arp` binary 
find({ arpPath: '/usr/sbin/arp' }).then(devices => {
    devices /*
    [
      { name: '?', ip: '192.168.0.10', mac: '...' },
