quitter

A simple way to abort from a command-line process when something goes wrong. This must exist as another package somewhere, but for the life of me I couldn't find it.

Example Usage

var fs = require('fs');
var quitter = require('quitter')();
var readFile = fs.readFile(__dirname + '/fake.txt', quitter(handleFile));
 
function handleFile(buffer) {
  console.log('here is the data buffer: ', buffer);
};
 

This would generate the following output when the fake.txt file does not exist:

An error occured, exiting:  { [Error: ENOENT, open '/home/doehlman/code/DamonOehlman/quitter/examples/fake.txt']
errno: 34,
code: 'ENOENT',
path: '/home/doehlman/code/DamonOehlman/quitter/examples/fake.txt' }

And if it did, this:

here is the data buffer:  <Buffer >
