Using Node.JS, how do I read a JSON object into (server) memory?

Background I am doing some experimentation with Node.js and would like to read a JSON object, either from a text file or a .js file (which is better??) into memory so that I can access that object quickly from code. I realize that there are things like Mongo, Alfred, etc out there, but that is not what I need right now. Question How do I read a JSON object out of a text or js file and into

Best way to access pixels of an image in JavaScript to do Image Processing?

I am trying to perform simple operations on image using javascript. To get the pixels of the image, I am drawing the image on canvas and then get the ImageData from canvas. But for large images, drawing them on the canvas takes a lot of time. Is there any other way of getting the image pixels without using the canvas element? I don't think you can have image manipulation in JavaScript w

在JavaScript中访问图像的像素以进行图像处理的最佳方法?

我正在尝试使用javascript对图像执行简单的操作。 为了获得图像的像素,我在画布上绘制图像,然后从画布中获取ImageData。 但对于大型图像,在画布上绘制它们需要很长时间。 有没有其他方式获得图像像素而不使用canvas元素? 我不认为你可以在JavaScript中使用硬件加速进行图像处理,所以无论是使用canvas还是其他技术,在JavaScript环境中都不会获得太多边缘效益。 如果你希望你的代码被硬件加速,你的代码必须被编译成

Good beginners tutorial to socket.io?

I am very new to the world of webdevelopment and jumped into the bandwagon because I find the concept of HTML5 very interesting. I am fairly confident on working with canvas and would now like to move over to websockets part of it. I have come to understand socket.io is by far the framework to work with, when we want to work with web sockets. Any pointers on what tutorial and examples to refe

好的入门教程socket.io?

我对网络开发的世界很陌生,并跳入潮流,因为我发现HTML5的概念非常有趣。 我对使用canvas的相当有信心,现在想转移到它的websockets部分。 当我们想要使用web套接字时,我已经理解了socket.io是迄今为止使用的框架。 任何关于什么教程和例子参考一个总假人指针将非常感激! 从Socket.IO开始,我建议你首先阅读主页上的例子: http://socket.io/ 在服务器端 ,阅读GitHub源页面上的“如何使用”: https://github.com/

Web Sockets questions

I have a couple of questions concerning Web Sockets. The latest Firefox 4.0 nightlies support Web Sockets. So does Webkit (Chrome 4 + Safari 4/5). Internet Explorer 9 is supposed to feature Web Sockets at some point according to Microsoft (before the stable release). Anyway, my questions are: I am building a JavaScript admin interface to manage a website. Should I use Web Sockets for the

网络套接字问题

我有几个关于Web Sockets的问题。 最新的Firefox 4.0夜晚支持Web套接字。 Webkit(Chrome 4 + Safari 4/5)也是如此。 根据微软的说法,Internet Explorer 9在某些时候应该具有Web套接字功能(稳定版之前)。 无论如何,我的问题是: 我正在构建一个JavaScript管理界面来管理一个网站。 我应该使用网络套接字的客户端服务器通信,而不是XMLHttpRequest的,如果我告诉你,我不需要在意浏览器的兼容性? 与XMLHttpReque

Using HTML5/Javascript to generate and save a file

I've been fiddling with WebGL lately, and have gotten a Collada reader working. Problem is it's pretty slow (Collada is a very verbose format), so I'm going to start converting files to a easier to use format (probably JSON). Thing is, I already have the code to parse the file in Javascript, so I may as well use it as my exporter too! The problem is saving. Now, I know that I can

使用HTML5 / Javascript来生成和保存文件

最近我一直在摆弄WebGL,并且得到了Collada阅读器的工作。 问题是它非常慢(Collada是一个非常冗长的格式),所以我将开始将文件转换为更易于使用的格式(可能是JSON)。 事情是,我已经有了解析Javascript中的文件的代码,所以我不妨将它用作我的导出器! 问题在于节省。 现在,我知道我可以解析文件,将结果发送到服务器,并让浏览器从服务器请求文件作为下载。 但实际上服务器与这个特定的过程无关,所以为什么要涉及它

Will HTML5 allow web apps to make peer

Is it possible to create a web app that, with the help of a central server, could create direct connections with other users of the same web app? I'm imagining a process similar to UDP hole punching. I've read about the new WebSockets API in HTML5, but it appears you must initiate the connection with a WS-compatible server before the fully-duplexed connection can begin. I'm thinki

HTML5将允许Web应用程序进行点对点

是否有可能创建一个Web应用程序,在中央服务器的帮助下,可以创建与同一Web应用程序的其他用户的直接连接? 我正在想象一个类似于UDP打孔的过程。 我已经阅读了HTML5中的新WebSockets API,但在全双工连接开始之前,您似乎必须先启动与WS兼容服务器的连接。 我更深入地思考一个在客户端之间建立直接连接的过程,服务器仅在初次握手时才参与进来。 注意:Java小程序不计数。 我只对标准浏览器技术感兴趣。 而不是聪明的
