##Chrome Packaged Apps

Introduction

Introduced at Google I/O 2012, Chrome packaged apps are a new way to develop apps that are running 'natively' within Chrome on the desktop as well as on Chrome mobile in the near future. I'm currently in the middle of a project where I develop a Chrome packaged app and in this article I would like to share my experience with the development of packaged apps.

Please note: This article should give you a basic insight of topics that I think are helpful to know for developing packaged apps. Furthermore I will give links to each topic, so you can dive deeper into that specific topic if you want to. It's not the goal of this article to act as a complete introduction to Chrome packaged apps, for a much more detailed overview of packaged apps development, please look at the official packaged app documentation.

This post examines the features of [R Markdown](http://www.rstudio.org/docs/authoring/using_markdown) 
using [knitr](http://yihui.name/knitr/) in Rstudio 0.96.
This combination of tools provides an exciting improvement in usability for 
[reproducible analysis](http://stats.stackexchange.com/a/15006/183).
Specifically, this post 
(1) discusses getting started with R Markdown and `knitr` in  Rstudio 0.96;
(2) provides a basic example of producing console output and plots using R Markdown;
(3) highlights several code chunk options such as caching and controlling how input and output is displayed;
(4) demonstrates use of standard Markdown notation as well as the extended features of formulas and tables; and 
(5) discusses the implications of R Markdown.

#Introduction

Developing Chrome Extensions is REALLY fun if you are a Front End engineer. If you, however, struggle with visualizing the architecture of an application, then developing a Chrome Extension is going to bite your butt multiple times due the amount of excessive components the extension works with. Here are some pointers in how to start, what problems I encounter and how to avoid them.

Note: I'm not covering chrome package apps, which although similar, work in a different way. I also won't cover the page options api neither the new brand event pages. What I explain covers most basic chrome applications and should be enough to get you started.

2. Understand the Tabs-Extension Relationship
3. Picking the right interface for the job
