Nodejs-code

This is a short tutorial explaining how to use the debugger that comes built-in to Node.js. It explains how to use the command line debugger to set breakpoints , step through the code, and analyze the debugging output.

Everyone loves NodeJS in part because it embraces a non-blocking philosophy; interactions are asynchronous and thus, theoretically, allow for faster all-around processing.

If you use open source and github you are probably used to creating issues and having them magically solved for you. You just npm install a new version and the issue is gone. Great right?

I recently had a problem where I wanted to store in a MySQL data store a series. (I’m re-writing Narrator, my story engine.) While testing out the import, I realized that I wanted to be able to look up the author on the fly, using the authorname rather than the author ID.

The Crypto module is one of the important modules available for Node.js, and allows you to use it for encrypting content, creating digests and creating public-key signatures...

As I said in my previous post I'm playing around with socket.io to see possible uses for this fantastic library. I've found cases when a simple message sent from the server to the client seems a little short on functionality.

It clearly says that the Node.JS is single threaded from our application point of view and it needs to wait to complete current user code to take another request.If my delay code was to fetch contents from file it should have processed differently as the I/O code will go into another thread.

I’ve been working more and more with nodejs and have to say I am really loving how easy it’s been to get to grips with. So here’s a quick example I created that illustrates how to make a simple JSONP call to a nodejs + express server.

Maintaining software is no walk in the park: writing modules is at once the most rewarding and most difficult thing you can do.

OpenShift was announced last May at Red Hat Summit as a response to Microsoft's Azure platform-as-a-service (PaaS) cloud, as well as to platform services from Amazon Web Services and a handful of other popular clouds on which developers chuck their code.

I would like to document an emerging set of programming conventions, philosophies, and values that I see evolving in the node.js community. I call this the node aesthetic.

A lot of Node.js projects seem to start with a debate: what to do with node_modules? The two obvious options are:

1. Every machine should “npm install” them from scratch
2. They should be checked-in

Event-driven programming can be overwhelming for beginners, which can make Node.js difficult to get started with.

Node. js for Beginners - Web Development Event-driven programming can be overwhelming for beginners, which can make Node.

Nobody likes link rot. Link rot breaks the Web. But in the age of Twitter, short URLs are a necessity. I think the best way to keep my short URLs from rotting is to take charge of the process myself.

Node.js is a perfect platform for creating event driven applications. Redis and WebSockets are great companions to Node.js. The following tutorial will walk through the steps to build a web application that streams real time flight information using Node.js, Redis, and WebSockets.

This is part 2 of a quasi-series on hardening node.js for production systems. The previous article covered a process supervisor that creates multiple node.js processes, listening on different ports for load balancing. This article will focus on HTTP: how to lighten the incoming load on node.js processes.

Last year, I wrote a blog post about events and node streams. In this post, I proposed an alternative API for streams: callback-oriented rather than event-oriented. For readable streams, the propos...

If you’re anything like me, you’re probably pretty sick of the whole node.js debate. Node has been called cancer (which Ted Dziuba called it in a rant ...
