NPM is the most used package manager for node.js and JavaScript ecosystems. By using the global packages mechanism, a node.js package can be easily integrated into system shell and just works like a native command line utility (or even an desktop GUI program).

Then you need to implement every single pages. You should figure out the common part and reusable part and put them together, and use some client-side or server-side mothods to merge all different part together and represent a perfectly metched web page to your audience.

Nowadays, in such a so called “web 2.0” era, what is loaded and rendered by a browser is not a traditional document-like web-page but a modern program-like web-application. And since the HTML5 and CSS3 ( as well as other “live standands” ) became widely used in most websites form top of Alexa ranking to those personal blog (like this), it’s rare to meet a pure static site(in terms of client end). The scorces drive all of world of web is in JavaScript, our hero. However, just as the name, “JavaScript”, indicates that it’s initial goal is only provide some simple way for website to use, JavaScript is not designed for large scale application. The conflict between the autologous fault of the language nature and the raising demand of a suitable language led to various solutions. Here in this post, I would like to talk about some things about RequireJS, a JavaScript file and module loader who modulize JavaScript code snippits and load them asynchoronously in the standand browswer environment.
