Node.js. It’s the latest in a long line of “Are you cool enough to use me?” programming languages, APIs, and toolkits. In that sense, it lands squarely in the tradition of Rails, and Ajax, and Hadoop, and even to some degree iPhone programming and HTML5.
Dig a little deeper, and you’ll hear that Node.js (or, as it’s more briefly called by many, simply “Node”) is a server-side solution for JavaScript, and in particular, for receiving and responding to HTTP requests. If that doesn’t completely boggle your mind, by the time the conversation heats up with discussion of ports, sockets, and threads, you’ll tend to glaze over. Is this really JavaScript? In fact, why in the world would anyone want to run JavaScript outside of a browser, let alone the server?
The good news is that you’re hearing (and thinking) about the right things. Node really is concerned with network programming and server-side request/response processing. The bad news is that like Rails, Ajax, and Hadoop before it, there’s precious little clear information available. There will be, in time — as there now is for these other “cool” frameworks that have matured — but why wait for a book or tutorial when you might be able to use Node today, and dramatically improve the maintainability.

依然是短篇入門電子書。對於 node 的使用場景闡述得更加客觀。

评分為什麼這是一本書?……
评分十頁的小書。????????????????????
评分10頁的短文。作者指齣node是為隻讀的小數據大並發的場景準備。其論據集中在node對json的原生支持以及其事件驅動的單綫程並發請求處理模型。這個解說還算自洽地說明瞭node對比helma和jaxer的不同。但不清楚這個場景是否是node團隊的目標場景。在綫閱讀:http://radar.oreilly.com/2011/07/what-is-node.html
