Live-LiveCoding: node.js @ SDN event

Hello Coders! Here’s the recording of my LiveCoding session at the SDN Event. In this session I’ve build a very basic website using node.js and express.js. I talk about Pug for templating and Sass for my css. I also explain some great features in Visual Studio Code. I also streamed the session to my LiveEdu.tv channel. Be sure to check that to find out when I’ll be streaming again. You can find the code build in the session at my GitHub. I want to thank SDN for organizing the event. Be sure to check their channel as well (it’s in Dutch).

The Express.js Route to Success | express.js router

Intro You probably want your node.js server to respond to requests that are coming in, specially when you are building a website. This can be complex and quite tedious to implement in vanilla node.js. Luckily express.js has done this for you.

It helps you with routing, error handling and it works very well other frameworks. Installing the express generator The…

Getting started with Node.js on ChakraCore

Intro Last year I started to use Node.js more and more. Personally I really like it. Using node.js on ChakraCore has some advantages over using V8. I’ve decided to get to know node.js a bit better and start a series of posts about it, beginning from the top. What is node.js? Node.js is described as interface to V8, Google’s JavaScript engine that also used in Chrome. Node.js enable you to write server-side code using JavaScript. It is uses an event-driven, non-blocking I/O mode.  This  very lightweight and efficient, but, as a trade off, you have have to implement every HTTP…

Poor Mans jQuery

A lot of people use jQuery in their HTML/JavaScript applications. There’s nothing wrong with that. But I’ve seen a lot of people use jQuery only to make it easy to find elements and they are not using any of the other jQuery functions. It’s pretty clear that writing a single ‘ $ ‘ instead of the way longer usages of various function on the ‘document‘ object, like getElementById. One of the functions on the ‘document’ object is the querySelectorAll function. This function brings a similar experience to vanilla JavaScript by taking selectors as a parameter.  So if we take a…

HTML5, Presentation, UWP app

Speaking about JavaScript UWP apps.

Last week I was invited by iSense to give a presentation about JavaScript Frameworks in Universal Windows Platform Apps. I decided my personal goal was to show people that JavaScript is a perfectly legit language of writing your apps for Windows 10, specially when you have a web development background. I started with an introduction about the way the JavaScript UWP apps work in Windows 10 and talked a bit about the great support of ES6 in Microsoft Edge. I then demonstrated how easy it is to convert a web application to a hosted UWP app, including what you could do in…

Styling default JavaScript UWP app controls

When working on my drum machine app I started changing the look and feel a little. I started my changing the black and gray to some more bright colors. Pretty quickly I ran into some issues with changing the look and feel of the default controls. The blue color is specified as a named color ‘Highlight’, which seems to be controlled by Windows. After searching for quite a while I came across some MSDN documentation that describe a couple of vendor specific CSS pseudo-classes to alter various elements of the controls. The whole list of pseudo-classes you can use to…

List item delay in Pivot

In one of my apps I wanted to have the items in a list with the list being in a Pivot control. I wanted to have the items slide in with a little delay, like they are in the Windows Phone mail app. I’ve been looking for that a lot, but couldn’t find anything. Until I stumbled upon the Pivot Control Sample app. The actual solution is demonstrated in this sample. It doesn’t seem to be documented anywhere else… Here’s how it’s done… All you have to do to get the delay on the items, or basically any HTML inside…
