Hi all, Any idea how one would go about preventing XSS attacks on a node.js app? Any libs out there that handle removing javascript in hrefs, onclick attributes,etc. from POSTed data? I don't want to have to write a regex for all that :) Any suggestions? ...

========================================================================= EDIT: I'm using node.js, so I don't have access to the DOM, and parsing with an HTML parser is not an option (it's not efficient enough to justify parsing through such a small amount of text) =======================================================================...
im writing an app with express. main file is called server.js one of the objects is var app = express.createServer(express.logger(), express.bodyDecoder()); then i have app.get("/",function(req, res){ res.send("Running"); } how do i use expresso, [or any other testing framework for that matter], to test the routes output? I looked a...
Setting npm up as the root user is straighforward and workds. Except you have to run npm commands as root (not recommended). So I thought I'd try setting it up as a non-root user. According to npm documentation, a non-root user without root access can set up npm by: creating a .npmrc file with root, binroot, and manroot pointing to...
Hi, I'd like to know what are the steps required to create a framework on top of node.js. I believe this can be a good way to learn, that's why I'm doing this! I've been checking other micro-frameworks and bigger frameworks but I'm not being able to understand where to start. I'd like your advice on this. Thank you. Edit: MVC Framewor...
The quick overview is this: for my web app I can write most of my functionality using CouchApp and CouchDB views, etc. I love the feature of CouchApp that pushes my code up to the server via replication- this makes the deployment cycle very easy. However, to do some arbitrary work not supported in couchdb and works around a few limita...
Hi, I am trying to make a node.js file uploader with a ajax progress bar. var formidable = require('./formidable'), http = require('http'), sys = require('sys'); http.createServer(function(req, res) { if (req.url == '/upload' && req.method.toLowerCase() == 'post') { // parse a file upload var form = new formidable.IncomingFo...
Hi, I'd like to know if it's possible to create a complete website using node.js (just like we do using Sinatra and Rails). Also, is there any framework as good as Sinatra and Rails? Is this the best use for node? Regards. ...

I'm implementing a server in node.js for a protocol that has unterminated packets. i.e: _________________________________________________________________________ | packet type | string length 1 | string 1 | string length 2 | string 2 | So I don't know the length of the packet until it has been fully parsed. This causes problems, becau...

I need to encode and decode IEEE 754 floats and doubles from binary in node.js to parse a network protocol. Are there any existing libraries that do this, or do I have to read the spec and implement it myself? Or should I write a C module to do it? ...

I'm using OSX 10.5 and playing around with Nodejs. I've managed to install npm and used it to install a couple of plugins. Well at least the installation says it has worked fine but when I try and load them in I get an error $npm install htmlparser Installs ok, then I create a file called test with var htmlparser = require("node-htm...
Node.js server is works on event based models where callback functions are supported. But I am not able to understand how is it better than traditional thread based servers where threads wait for system IO. In case of thread based model, when a thread needs to wait for IO, it gets preempted so doesn't consume CPU cycles hence doesn't con...
I wonder what server side solution Google used for Google Wave. I have heard that they used Node.js for this. Is that true? Or did they use other non-open source solutions? ...
So Node.js uses event loop for non-blocking IO. I wonder if that event loop is in the same thread as Node.js main for handling requests? ...
I want to build a live application that supports server-push (chat, feeds, live notification and collaboration etc). I have looked into Node.js and found it quite interesting and appropriate for such things. I have also looked into AMQP/RabbitMQ, but I don't get these quite. My questions: How does AMQP/RabbitMQ compare to Node.js? C...
