Simple helper for handling error and success with two different callbacks


Handle success and failure with two different callbacks. Lets you get rid of most if (err) return cb(err); constructs.

Send errors reported by fs.readFile straight to cb:

var passError = require('passerror'),
    fs = require('fs');
function getLines(fileName, cb) {
    fs.readFile(fileName, 'utf-8', passError(cb, function (contents) {
        cb(null, contents.split(/\r?\n|\n?\r/));
