passerror

Simple helper for handling error and success with two different callbacks

passError

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(fileNamecb) {
    fs.readFile(fileName, 'utf-8', passError(cb, function (contents) {
        cb(null, contents.split(/\r?\n|\n?\r/));
    }));
}
