A Dexplexer example for working with orca on multiple port

plexer.js

const dgram = require('dgram')
const PortMaps = require('./portmaps.json')

this.server = dgram.createSocket('udp4')
this.listener = dgram.createSocket('udp4')

this.listener.on('message', (msg, rinfo) => {
let parts = `${msg}`.split("M")

let maps = parts[0].split("")
let message = parts[1]

maps.forEach(map => {
if (PortMaps[map]) {
let port = PortMaps[map]
console.log('sending to', port, message)
this.server.send(Buffer.from(`${message}`), port, '127.0.0.1', (err) => err && console.warn(err))
}
})
})

this.listener.on('listening', () => {
const address = this.listener.address()
console.log(`listening for UDP:\n ${address.address}:${address.port}`)
})

this.listener.on('error', (err) => {
console.log(`Server error:\n ${err.stack}`)
this.listener.close()
})

this.listener.bind(process.env.PORT || 49161)
