Binding.scala is a one-way data-binding library written in Scala. It lets you create reactive user interfaces by writing concise Scala code. In this post, I’ll guide you step by step through the basics, as well as creating a simple dynamic web page. On top of that, I will discuss some undocumented issues I faced, which might be interesting for you if you decide to give Binding.scala a chance in your next project. Read more

Introduction

This blog post was created to see how Scala.js is holding on and have some fun with programming. I decided to do a simple mini-game using Scala.js and Three.js libraries.

I will explore Scala.js from practical perspective. You’ll see the perks of using typed languages in frontend. We are also going to take a look under the hood and see some generated JS code. Finally I’m going to present some advantages and disadvantages of Scala.js and try to answer the question: Is Scala.js production ready ? Read more

The Problem

In my previous post we have written a simple app with Scala.js. In the end we managed to do everything we wanted to, but as we added more and more code a problem appeared – state management, the real app killer. Although our app didn’t do anything advanced, state handling and UI updates forced us to write a lot of additional code.

That post has shown that Scala.js allows us to write browser apps, but it also demonstrated that these apps can be vulnerable to other ills of frontend programming. To fix this issue we need to simplify our codebase. One way to do that is by adding a binding between the UI and what data our app holds. This way if the data changes in one place it will be automatically propagated to the other. We will implement this using Reactive Extensions. Read more

What is Scala.js?

Scala.js is compiler that targets JavaScript, unlike the traditional Scala compiler which targets JVM bytecode. What it means in practice – with Scala.js you can write Scala code that will be executed in the browser. Read more
