can't connect to localhost

[a2435191]

To preface, I have literally zero experience with Node or web stuff. I'm trying to run the following code on MacOS 1.15:

const mineflayer = require('mineflayer')

const bot = mineflayer.createBot({
    host: 'localhost',
    port: '25565',
    username: '[email protected]',
    hideErrors: false
})

But I get the following error:

Error: connect ECONNREFUSED 127.0.0.1:25565
    at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1148:16) {
  errno: -61,
  code: 'ECONNREFUSED',
  syscall: 'connect',
  address: '127.0.0.1',
  port: 25565
}

Should I be configuring localhost to listen on 25565 somehow?

25565 is the default port of minecraft servers, if you changed it you need to set it to whatever port your server use.
Make sure you have a server running locally and that you can connect to it properly using your client.

i have set my port to my localhost port but when i run the file it changes it back to 25565

Error: connect ECONNREFUSED 127.0.0.1:25565 at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1157:16) { errno: -4078, code: 'ECONNREFUSED', syscall: 'connect', address: '127.0.0.1', port: 25565 }

I think you need to write the port as an integer, not as a string
