How to start Node.js app windowless in Windows

Node.js is getting more popular by the day. It breaks JavaScript free from the browser. I would love to auto start an application – much like a Windows service – without keeping a console window open. There are many services to wrap node applications into an executable, but I like to stick with just Node. This small trick will make your Node application windowless on Windows.

Strongly Typed Events 0.3.0 – now with Signals

Turns out that I needed an even smaller type of event: the signal. It is an event that has no data; it just fires. The Strongly Typed Events project started with the IEvent event that was styled after .Net. Then the ISimpleEvent was added in 0.2.0, for scenarios when no sender is necessary. Now I’ve added the ISignal to version 0.3.0.

Strongly Typed Events 0.2.0 – now with Simple Events

A while ago I started a GitHub project for Strongly Typed Events in TypeScript. I’ve uploaded the second version (0.2) with support for ISimpleEvent and I changed the way you can expose the dispatcher as an event. The code is 100% backwards compatible with version 0.1 – you might need to update some references.

Adding named events to your TypeScript classes (Part 4)

Need to add named event support to your class? Implement the IEventHandling interface or extend from the abstract EventHandlingBase class. In this tutorial I explore how you can give your class named events.

Strongly Typed Events in TypeScript using an event list (Part 3)

In this tutorial I explore how an event list can be used to support scenarios with classes with a multitude of events. There is a way to decrease the number of private backing variables using an EventList object.

Using strongly typed events in TypeScript with interfaces (Part 2)

In a previous tutorial I explained how events can be implemented as properties on a class using Strongly Typed Events for TypeScript. Let’s explore how these work on interfaces. Interfaces work a little different, because they don’t have getters and setters on them (at least nog in TypeScript 1.8). Let’s explore how these work on interfaces.

Strongly typed event handlers in TypeScript (Part 1)

As a C# programming I have a lot of interest in the TypeScript project. Lately I’ve been playing around with it to look what it can do. I found myself in need of some event handling, so I decided to build something that looks like the event handling .Net gives you.

Login Credentials Generator – in JavaScript

Many small applications need to store user credentials, but it’s hard to create a good username/password infrastructure. What if you could just use a small XML file with credentials that don’t actually stores the password, but just a hash and some salt.

For a small cloud project I ended up creating such a solution. This blog explains how to generate the credentials that can be stored in the XML. The aim is to make a solution that works on the client using JavaScript.

Little life saver: parsing HTML entities

Recently I had the pleasure of building a calculator example exercise. Begin a good programmer I used the some HTML entities as values on the buttons: ×, ÷ and ± as values. It turned out to be quite difficult to parse them with native JavaScript. It is not so hard with LoDash or jQuery, but I wanted to do it native.

Double Click to Select All Code

When you want to display code, you are probably using PRE elements. The fact that these elements can contain markup makes them perfectly suited for syntax highlighting. Some plugins make it easier to copy the code using a button. Google Prettify has no such option. Let’s see if we can make copying easier by providing a “double click to select all”-feature to our pre fields.
