I made a short NodeJS script to interact with a 3rd party website (their TOS officially allows automated/scripted interaction as long as it's not spamming).

Short overview:

1. Connects to the Site's websocket




2. Messages are arrays of objects - loop through those




3. If one object's "id" property is "12345", send POST to the same website

I am now trying to cut the time between receiving the socket event and the POST request reaching their server by as much as possible. Counting milliseconds here.

Things I thought about:

• 
  

  Use a more powerful machine than a raspberryPI or a low budget VPS

  
  
  
  • Would this even make a difference for such a small task?
  
  


• 
  

  Get a VPS that is as close to the website's server as possible

  
  
  
  • How could I find the best one? (The website is running cloudflare)
  
  


• 
  

  Change something about the code to speed up the post request

  
  
  
  • Is there ANY way to make this faster than using request.post()?
  
  


• 
  

  Change something to receive the websocket message earlier

  
  
  
  • When i have multiple connections to the same socket opened, I can see that socket A sometimes receives two messages with 5 objects each while Socket B might receive the same 10 objects later but in a single array. Any way I can use this?
  
  


• 
  

  Loop ... faster?!

  
  
  
  • Array length varies between ~5 and ~100 - they come in every few seconds. Post is only being triggered once an hour or so.
  
  



• Use something else besides NodeJS?

Here is the code:

const WebSocket = require('ws');
const ws = new WebSocket(webSocketPath);

ws.on('message', function incoming(data) 
 var socketData = JSON.parse(data).data;
 for(var i = 0; i < socketData.length; i++)
 if(socketData[i].id == "12345")
 sendPost(socketData[i])
 
 
);

function sendPost(socketObject)
 request.post(url:postURL, json: socketObject, function callback(error, response, body) 
 console.log(body);
 );

Any help is appreciated - I am really trying to push this to the absolute limit here!

Have a nice evening, thank you!
