npm install wake_on_lan --save  # use the library
npm install wake_on_lan -g      # optional global wake utility 

To wake a machine with a given mac address do:

var wol = require('wake_on_lan');

wol.wake('20:DE:20:DE:20:DE');

wol.wake('20:DE:20:DE:20:DE', function(error) {
  if (error) {
    // handle error
  } else {
    // done sending packets
  }
});

var magic_packet = wol.createMagicPacket('20:DE:20:DE:20:DE');

See windows notes and the wake utility.

MAC addresses are strings and may use any separator or no separator at all:

'20:DE:20:DE:20:DE'
'20-DE-20-DE-20-DE'
'20DE20DE20DE'

wake(mac, [options, callback])

Send a sequence of Wake-on-LAN magic packets to the given MAC address. The callback is called when all packets have been sent or an error occurs. The options object may have the following properties:

createMagicPacket(mac)

Returns a buffer with a magic packet for the given MAC address.

wake [options] MAC

wake 20:DE:20:DE:20:DE
wake -a 192.168.1.255 20-DE-20-DE-20-DE
wake --num_packets 10 --interval 50 -p 9 20DE20DE20DE

Because windows routes global broadcasts differently from unix systems, it is necessary to specify a broadcast address manually, e.g:

wol.wake(someMac, { address: "192.168.2.255" }, wakeCallback);

Use os.networkInterfaces() to calculate the broadcast address dynamically. See @mwittig's comment for further information.
