In the world of technology and development, there are many different types of frontend frameworks that are used. In this post, we’ll discuss two of the biggest ones, Angular and React, and one of the newer ones, Blazor.
With the evolution of microservices and the scalable nature of modern distributed architectures, batch processing seems to be falling out of favor. In fact, the term batch processing itself seems to be unfavorably associated with monolithic mainframe applications and thus does not seem to have much appeal.
Unless, of course, you are working on a project that is being designed to replace or modernize one of those mainframe applications. If that is the case, then likely some sort of batch process has come up with a non-functional requirement that needs to be dealt with in the new system.
For this specific concern, a very powerful framework has been provided: Spring Batch. It has many of the same features of a mainframe batch process like restart/recovery, chunk processing, and error handling along with exit codes. This framework allows developers to create powerful batch processing applications in the Spring Framework and enjoy the rich backplane of capabilities that this provides.
Continuing with the modernization thread, you will likely be tasked with providing some assurances to the business that the new, modernized process will produce the same outcome as the one that is being replaced. Here is where testing comes in, and where Cucumber specifically shines.
Cucumber provides behavioral testing support in the Spring universe. This allows developers and business users to collaborate through a common set of conventions and verbiage to validate that the app is behaving how the business intended as well as how the developer coded it.
In this post we will cover the following:

So, you’ve learned JavaScript and now you’re wanting to get into Angular. But where do you start?
There are quite a few examples out there. One of the best ideas I have personally found useful for a new developer to learn is how to do Create, Read, Update and Delete operations.
In this blog we’ll go through the process of building a simple, working Angular address book application with C.R.U.D. operations. By the end, and by studying the full, working code, you should have a better grasp on Angular.
In this updated blog post, we’ve built an employee directory using Angular 2 with unit tests, gone over some differences between Angular 2 and version 1, and introduced some of the features of TypeScript.
I originally wrote this article/application when Angular 2 was still in beta. Now that it has released officially, I have updated the source code to reflect updates made to the Angular 2 framework for release. My approach to get this working was to start from the new Angular 2 quick-start project, port in the original application source code, and refactor as needed to make things work. Let’s get started…
