[nodemon] app crashed - waiting for file changes before starting...

code in my index.js

const express = require("express");

const app = express();

app.get("/", (req, res) =>
  res.send(console.log("Hello world the server is now running"))
);

app.listen(1000, () =>
  console.log("The server is running on port 8000 successfully")
);

tried :

• installed npm install -g kill-port*
• also tried to execute npm kill port command but it showed that it has killed it but when i checked it was still listening*

expected: the listening port should be killed but it didn't got killed. after executing the command npx kill port 8080

resulted: after running the index.js file got this error

code: 'EACCES',
  errno: -13,
  syscall: 'listen',
  address: '0.0.0.0',
  port: 1000

Answer 1

Simple, your NodeJS server is listening on port 1000, but you are trying to kill port 8080. use

npx kill port 1000
