NW.JS (node-webkit) – An Introduction Node webkit allows HTML5 applications to run in a desktop. It uses NodeJS and Chromium. Both are using the same V8 javscript engine. Since this runs as a desktop application, it doesn’t have the sandbox restrictions. So in the same page, you can open a file from file-system and then… Continue reading »
Creating and Deploying Local Scala SBT Packages In the last few months we have discussed various features of scala. Some features required using other scala packages. In this post, let’s discuss how we can create our own artifacts. We can also discuss how we can use these packages in other scala projects locally. Let’s create… Continue reading »
Using TypeSafe’s Config In Scala Our application behavior is generally defined with a set of configurations. Instead of hard-coding the values in the code, we like to define them separately in a configuration store. In this post, we are going to see how we can define configurations using TypeSafe’s config. Let’s create a SBT project…. Continue reading »

Compound Types in Scala In the previous post we looked at Mixin composition with traits in Scala. This post is about a similar concept, called Compound types. The syntax is exactly the same, it uses the familiar with keyword. But there is some differences. Mixins are used to define types or instantiating them. On the… Continue reading »
Mixin Class Compositions in Scala Scala allows a class to inherit from other classes. With this inheritence, it can also mix-in behaviors from other classes. This allows additional behavior to be added to the classes. Traits can be added to provide generalization of orthogonal behaviors then mixed-in to the class definitions. Here we have introduced… Continue reading »
Scala’s Singleton Objects are powerful Scala provides the support for singletons by introducing object, which provides the anonymous type definition and its instantiation. The same instance is used throughout the life of application. This is different from the Gang of four’s singleton implementation that we are so used to. I have found there are various… Continue reading »
