Hope this helps someone :)
I used the broadlink IR converter node package and the broadlink codes from AnilDaoud's broadlink bridge config to come up with this.
import { broadlinkToPulesArray, pulesArrayToBroadlink } from 'broadlink-ir-converter';
const one = '260060000001289512131213111412131213121411131213123813381139113912381238123813381238113913371213123912121313111412131213111412381213123812381437110005260001274b12000c630001284b12000c630001284a13000d050000000000000000'
