checkerr v0.1.0

Checkerr

Check for callback errors and handle them in one line

Exit process on error

var check = require('checkerr').andExitProcess;

doSomething(function(err, result)) {
	check(err);
	doActualStuff(result);
});

Call a higher callback on error

var check = require('checkerr').andCallHigherCallback;

function mainFunction(topmostCallback) {

	doSomething(function(err, result)) {
		if(check(err, topmostCallback)) return;

		doActualStuff(result);
	});

});

To mock out, with mockery e.g.

mockery.registerSubstitute('checkerr', 'checkerr/mock-disable');
