Wake-on-LAN utilities for Deno

Synopsis

To wake a machine with a given mac address do:

import { wakeOnLAN } from "https://taisukef.github.io/deno_wake_on_lan/wakeOnLAN.js";

await wakeOnLAN('20:DE:20:DE:20:DE');

$ deno run -A --unstable wake.js

See windows notes

Reference

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'

Function wakeOnLAN()

wakeOnLAN(mac, [options])

Send a sequence of Wake-on-LAN magic packets to the given MAC address. The options object may have the following properties:

Property	Description	Type	Default
address	The destination address	String	255.255.255.255
num_packets	The number of packets to send	Number	3
interval	The interval between packets in milliseconds	Number	100
port	The destination port to send to	Number	9

Function createMagicPacket()

createMagicPacket(mac)

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

Windows Notes

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

wakeOnLAN(someMac, { address: "192.168.2.255" });

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