How to handle uncaught exceptions

I want to log the uncaught exceptions with Winston and exit process. I’ve configured logger like this

var winston = require('winston');
var logger = new (winston.Logger)({
    transports: [
      new winston.transports.File({ filename: './all-logs.log', timestamp: true, maxsize: 1000000 })
    ],
    exceptionHandlers: [
      new winston.transports.File({ filename: './exceptions.log', timestamp: true, maxsize: 1000000 })
    ],  
    exitOnError: true,
});

Then try throw one error, but no exceptions.logs file was created throw new Exception(“Error here …”);

Did I have the right configuration?

@gowthaman-i2i this is the winston based example:

var winston = require('winston');
var logger = new (winston.Logger)({
    transports: [
      new winston.transports.File({ filename: './all-logs.log', timestamp: true, maxsize: 1000000 })
    ],
    exceptionHandlers: [
      new winston.transports.File({ filename: './exceptions.log', timestamp: true, maxsize: 1000000 })
    ],  
    exitOnError: false, // <--- set this to false
});

but @3rd-Eden is correct this can be handled in multiple places 👍
