Nodejs-code

Recently I blogged about how I like to build my JavaScript “classes”. I personally prefer the module pattern: it provides true encapsulation and doesn’t expose unnecessary methods and properties,...

NodeJS & Express: get URL image and refresh ALL linked screen Use NodeJS and Express web framework to implement a very cool effect: in the webpage, user inputs a URL to upload a image when subm...

This is part II of the post on my experiences from working with a Node.js and MongoDB solution. Read part I of this post to learn more about OS support, Node.js guidelines, services, tools and more.

I was recently on a client facing project for Bocoup and needed to store millions of tweets that contained sentiment analysis of the text. From this sentiment gathered along with other various metadata, I was tasked with creating a scalable API that could query/filter the data retrieved.

With Meshcraft you can organize your notes/presentations/texts in a mesh using your browser.

I recently had a chance to get familiar with the Mocha test framework for NodeJS and wanted to provide a really simple introduction to it. Assuming you have node and npm installed, you'll want to install mocha as a global npm module, which means using the -g flag.

Node.js is a brilliant product. It gives you so much freedom (... and also responsibility) and I think it's ideal for single purpose web servers.

I needed a two-way communication gateway that would pass data between a socket and a device connected to my serial port (more about why I needed that, in a later post). Here is what I’ve come up...

Node.js production lessons learned....

I am working on a very simple game using NodeJS and Socket.IO. I decided to separate my game and chat communication into two namespaces in Socket.IO to make the logic a bit easier to follow. One problem I encountered was that I wasn’t sure how to broadcast to all connected clients in a specific namespace. If you’re not dealing with namespaces, it’s simple:

Node is an innovative new platform available that allows you to quickly and easily build fast, scalable network applications, with just a few clicks of the mouse.

Reading a lot recently about mobile optimization, I have started doing some HTML5 prototyping using non-traditional methods to build mobile web apps.

NodeJS & Express: Upload Images There is an excellent article showing to use Node.js and Express to upload file/image. For the upload form:

One of the joys of enterprise programming is working with legacy applications. Recently I had to update a legacy application to reflect some changes to a third party HTTP API that it relied upon. The third party had published the API specifications but, as is often the case, did not provide an implementation to perform integration tests against.

This weekend I was faced with the task of putting a nodejs application into production mode. Most of the development happened offline with each developer running local instances of node and using g...

I have recently added a third blade to my little asynchronous programming swiss army knife: the generator blade. Looks sharp! Here are some details. Generators Generators are JavaScript’s flavor ...

Yes, nodejs code is written in Javascript (the clue is in the js part of the name), but it’s actually defined as Event Driven, Asynchronous IO.

Welcome to the first installment of justjs.com, a highly autobiographical blog about full-stack web development in node.js, MongoDB and JavaScript!
