サバクラ両方で動く JavaScript の大規模開発を行うために

考えてみれば Model-View-Controller とか MVC ってよく聞くよね。実際どんなものか知ってる？ 抽象的に言うなら「オブジェクト情報の保持されるグラフィック・システム (つまり、ラスターではないグラフィック。ゲームとか) 上に構築された、表示系を中心としたアプリケーションにおいて、主要な機能どうしの関わりをうまく分離すること」とでも言おうか。もう少し深く考えを押し進めてみれば、これは当然、他のさまざまなアプリケーションにもあてはまる言葉 (bucket term ?) だ。

過去に多くの開発コミュニティが MVC による解決案を提供し、それによってよくあるユースケースにうまく対処し、地位を築くことができた。例をあげるなら、Ruby や Python コミュニティは Rails や Django を作り、MVC アーキテクチャを実現した。

I needed a newer version of ImageMagick than is available on the yum packages on Amazon Linux. I tried using the remi repo but it failed with dependency errors. Here is what I did to install ImageMagick with support for PNG, JPG, and TIFF.

download the most recent package

wget http://www.imagemagick.org/download/ImageMagick.tar.gz

uncomress the package

Friendly URLs

By default, Rails applications build URLs based on the primary key -- the id column from the database. Imagine we have a Person model and associated controller. We have a person record for Bob Martin that has id number 6. The URL for his show page would be:

/people/6

But, for aesthetic or SEO purposes, we want Bob's name in the URL. The last segment, the 6 here, is called the "slug". Let's look at a few ways to implement better slugs.

The following is a VERY rough draft of an article I am working on for Alex MacCaw's @maccman's Book. It is very rough, but even now a worthwhile read. Suggestions / comments are very welcome! Please help me :-)

Introduction

JavaScriptMVC (JMVC) is an open-source jQuery-based JavaScript framework. It is nearly a comprehensive (holistic) front-end development framework, packaging utilities for testing, dependency management, documentation, and a host of useful jQuery plugins.

Yet every part of JavaScriptMVC can be used without every other part, making the library lightweight. Its Class, Model, View, and Controller combined are only 7k minified and compressed, yet even they can be used independently. JavaScriptMVC's independence lets you start small and scale to meet the challenges of the most complex applications on the web.

This chapter covers only JavaScriptMVC's $.Class, $.Model, $.View, and $.Controller. The following describes each component:
