When you're developing in Node.js, you're likely to run into these terms - "monolithic" and "modular". They're usually used to describe the different types of frameworks and libraries; not just HTTP frameworks, but modules in general.

At a glance

Monolithic: "Batteries-included" and typically tightly coupled, it tries to include all the stuff that's needed for common usecases. An example of a monolithic web framework would be Sails.js.
Modular: "Minimal" and loosely coupled. Only includes the bare minimum of functionality and structure, and the rest is a plugin. Fundamentally, it generally only has a single 'responsibility'. An example of a modular web framework would be Express.

Coupled?

In software development, the terms "tightly coupled" and "loosely coupled" are used to indicate how much components rely on each other; or more specifically, how many assumptions they make about each other. This directly translates to how easy it is to repla

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

Prerequisites

#How to use ZbarSDK in Swift(XCode 6.2, base SDK iOS 8.2)

##Steps

Download ZbarSDK and drag ZbarSDK folder in Swift project, setup buiding settings according to the zBarSDK tutorial
Add #import "ZBarSDK.h" in YourApp_Bridging_Header file
In your ViewController add ZBarReaderDelegate, setup ZBarReader, receive barcode data

##Posible building issues:

Missing required architecture arm64 in file ...
Reason: the libzbar.a is not compiled to arm64 architecture

Protocol-Oriented Programming in Swift

Speaker: David Abrahams. (Tech lead for Swift standard library)

"Crusty" is an old-school programmer who doesn't trust IDE's, debuggers, programming fads. He's cynical, grumpy.
OOP has been around since the 1970's. It's not actually new.
Classes are Awesome
- Encapsulation
- Access control
