One of the major differences between AngularJS 1.x and Angular 2 and beyond is the shift to components. Even though components were introduced in AngularJS 1.5, controllers are still often used. Embracing components provides many advantages, such as proper loosely coupled components, re-usability and so on. One drawback to the component-based approach is state management […]
If you worked with Spring boot before, you know it, there are various starters out there. These starters automatically configure all kind of things so that you no longer have to. This allows you to get started more quickly, and not to be bothered about configuration that is usually a copy-paste from something else. The […]
Monitoring is an essential aspect to the maintainability of applications, it’s no surprise that there are many platforms out there that allow you to properly monitor your applications. Usually, monitoring platforms work by using a time series database, which is a database optimised for time-based information, such as application metrics. Then on the other hand […]
When working at an Angular project, there are many choices for a UI kit. You have Angular Material, ng-bootstrap and a few more. My favourite UI kit is probably Project Clarity, open sourced by VMWare.
You might have heard of the term cross-cutting concerns in the past. If not, cross-cutting concerns are concerns that apply to all layers of the application. Examples of these concerns are logging, monitoring, security, … . If you think about it, some cross-cutting concerns also apply to microservices. Perhaps you want to monitor how long […]
As soon as you write your first web application with Spring, you probably want to secure it. Spring has a project called Spring Security that does most of the generic stuff for you. Just plug in a service that provides the user details (from a database, LDAP, …) and configure the endpoints and you’re ready […]
A few weeks back, I went to Devoxx, an annual Java conference located in Belgium. One of the few hypes there was Spring framework 5 and the upcoming release of Spring boot 2.0. With this tutorial I’ll show you how you can get started Spring boot 2.0.
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.
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.
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
