I got node:events:346

I made a new node project with npm init.

When I enter command ➜ nodemon index.js

I got Error

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

and I am using LINUX(UBUNTU) so how can I avoid this.

and thankyou in advance for helping me.

Solution

One way of doing it is to running pkill -f nodemon and then restart the server
You could also apply a delay to your nodemon instance as such :

nodemon --delay 500ms index.js

This link sums up the rest for you :

You should also add :

process.once('SIGUSR2', function () {
  process.kill(process.pid, 'SIGUSR2');
});

process.on('SIGINT', function () {
  // this is only called on ctrl+c, not restart
  process.kill(process.pid, 'SIGINT');
});
