Webhook to Websocket Proxy (useful to redirect HTTP Webhooks to devices behind a NAT i.e. Raspberry PIs) - expects at least the minimum JSON outlined in body-min.json as Body - additional attributes are of course addable

body-min.json

{
  "secret": "test",
  "service": "IFTTT",
  "event": "button"
}

proxy.js

const express = require('express');
const bodyParser = require('body-parser');

const app = express();

const http = require('http').createServer(app);
const io = require('socket.io')(http, {pingInterval:15000});

app.use(bodyParser.json());

app.set('trust proxy', true);

let processSecret = 'test';


app.all('/:service', (req, res) => {
        let {secret, service} = req.body;
                if(secret === processSecret){
                    io.emit(service.toLowerCase(), req.body);
                }
        res.json({received: true});
