Configuration as a microservice

In my last few tutorials, I’ve covered some aspects that are really important with microservice, such as a discovery service like Eureka and a circuit breaker like Hystrix. Another thing that might be useful when working with microservices is to provide your application configuration as a microservice as well.

Using the Netflix stack with Spring boot: Hystrix

Recently I wrote some articles about the various Netflix components and how they fit into a microservice architecture. In this article I will talk about the next component that is usable with Spring boot and that’s Hystrix.

Showing a loader with Angular 2

We’ve already done quite a lot to get a working pokédex with Angular 2. However, there are still two things that bother me: If the API request takes a while, the user wont notice it. The page will just be blank When we open the application, we get a simple “Loading…” message

Animating with Angular 2

We’re getting pretty far already with our Pokédex. We’ve already implemented a service with the Pokéapi, an overview and a part of the detail page. The next thing I’m going to look at is how to animate stuff with Angular 2. If you’re just like me and enjoyed the good ol’ days with AngularJS 1.x, […]

Implementing your own pipes with Angular 2

Now that we’ve set up a project with Angular 2, with a service to fetch data from our REST API and some components and routing to show an overview of pokémons, it’s time to show some more detailed data. The component I’m going to be working on will be using the PokemonAbilityInfo object, which contains […]

Changing your page title when a route changes with Angular 2

Last time, we implemented our pokémon detail view by using routing to switch between the overview and the detail. However, currently we still have the same title across our entire application. Usually when you have an application with multiple pages, you want to change the page title depending on the page the user visits.

Using routing with Angular 2

Last time, we pretty much finished our pokédex overview by implementing some pagination. Now that the pagination is behind us, we can focus on creating a more detailed view for our pokémons. If you remember when we wrote a service, we actually provided two functions, a findAll() and findOne() function. However, we didn’t use the […]

Creating a pagination component with Angular 2

Last time, we made a simple pokédex overview, but we’re missing something on our overview… . Right now, we’re seeing only the first 20 pokémons, and we have no way to view any other pokémon. So let’s change that!

Rapid prototyping with Spring Boot and AngularJS

Recently I wrote an article about writing modern webapps with Spring Data REST and AngularJS. It’s not that hard to write, but it can be done even easier with Spring Boot as pointed out in the comments by Greg Turnquist. I already planned on trying out Spring Boot after some amazing articles about Spring Boot […]

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.

Validating the input of your REST API with Spring

In the next few weeks I will be writing a small web application and in these articles I’m going to explain certain aspects of it. Previous time I mentioned how you could secure your REST API (partially), and this time I will be talking about how to validate the input you send to the REST […]

Making your AngularJS application grunt

A while back I wrote a small application to show you the main components of AngularJS, demonstrating controllers, services, filters and (custom) directives. In this tutorial I’m going to modify that application a bit and integrate GruntJS into it. For those who are wondering what Grunt is, well, it’s the task runner written in JavaScript, […]

CloudFlare, good or bad?

If you’re a developer like me and you spent some of your time on Reddit or StackOverflow, you probably might have encountered some articles about CloudFlare last week, like CloudFlare is ruining the internet (for me) and CloudFlare is ruining Stack Overflow for me with its recaptcha. Reading these articles made me want to evaluate […]
