Like I said before, the app I’m going to build in this tutorial, is an application where you can add/remove songs and rate those. We have several components to implement, so let’s start.

Writing apps with React.js: Build using gulp.js and Browserify

Previous week I went to Devoxx and Pratik Patel gave a great talk about React.js. This was enough for me to start playing with the library. React.js is a JavaScript library for building user interfaces by writing components. It’s a view-oriented library which allows you to write isomorphic components which can be used both in […]

How to drink gulp.js

A while back I wrote an article about how to use Grunt to build your application. However, recently there’s a new player on the market called Gulp. I’m not going to compare the two and tell you which one is better, but I’m going to use the same application and try to achieve the same […]

Using WebSockets with Spring, AngularJS and SockJS

A while ago I wrote a tutorial about writing a web application using Spring, AngularJS and WebSockets. However, that tutorial only used a fraction of what WebSockets could do, so in this tutorial I will explain how you can write a small chat app using the same frameworks; Spring, AngularJS, Stomp.js and SockJS.

Angular-powered forms

In the previous tutorials about AngularJS I already used some forms, but I never went into detail about them or about form validation. In this tutorial that will probably change, as I will explain you how you could use AngularJS validation and write your own custom validators.

Adding some D3 magic to AngularJS

In my previous tutorials I covered the basics of creating a basic AngularJS application containing services, controllers, filters and directives. It explained most of the basic parts, but in a real application you usually combine many frameworks together to form a solid webapplication. In this tutorial I’m going to show you how you could combine […]

You have to love JavaScript’s type coercion

JavaScript… some people love it, other people hate it. One of the many good/bad discussions in JavaScript are about its weak and dynamic typing. Because of that, type coercion exists.

Testing your Spring Data JPA repository

With Spring Data JPA, persisting data is quite easy. You no longer need to write complex DAO’s or repositories, no, all you need is an interface. If you look at my Spring Boot tutorial, you will see that by writing a few lines of code for creating our interface, we’re able to read, update, delete and […]

Utilizing cache abstraction with Spring boot and Ehcache

Caching is a very common operation when developing applications. Spring made a neat abstraction layer on top of the different caching providers (Ehcache, Caffeine, Guava, GemFire, …). In this article I will demonstrate how the cache abstraction works using Ehcache as the actual cache implementation.

Dojo domReady vs ready

One of the biggest misconceptions in Dojo is what module to choose to create a document-on-load event handler. In Dojo there are two modules that are commonly used, called dojo/ready and dojo/domReady. In this small tutorial I will explain you what the differences are and in what situation you should use them.

In the past couple of weeks I’ve written a few simple applications using Spring boot. With Spring MVC it’s also quite easy to serve REST API’s. In this article I’ll show you how to create such a REST API and how to consume one using RestTemplate.
