Runner

Middleware style function invocation, run a series of asynchronus functions in order.

Example

var Runn = require('runn');

var run = new Runn();

run.before(function(data, done){
	data.foo = 'bar';

	asyncOp(function(err, data){
		done(err);
	});
}, function(data, done){
	data = syncOp(data);
	done();
});

run.middle(function(data, done){
	db.update(query, data, function(err, data){
		data = data;
		done(err);
	});
});

run.after(function(data, done){
	data = translateObj(data);
	done();
});

run.exec({foo:'bar'}, function(err, data){
	console.log(err); // boolean
	console.log(data); // your data
});
