We have consultants who specialize in moving old to new, renovating dilapidated code bases, and designing brighter futures for enterprises who have been vendor-locked for most of their existence. We have come across some repeated patterns and strategies for how to approach modernization of legacy systems. In this blog, we will cover a strategy that is very popular right now, Re-Platforming.

The basic flow of this post will be:

Introduction to Modernization
High-level definition of the Re-Platforming Strategy for Modernization
Sample of Re-Platforming using Keyhole Syntax Tree Transformer, COBOL –> Java
Additional thoughts on the value/risk of this strategy

A Test-Driven Development Introduction to Angular 2 – Part 2

Matthew Brown Angular, Articles, Development Technologies & Tools, JavaScript, Single-Page Application, Testing 7 Comments

In this updated blog post, weโ€™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…

Spring Boot – The Right Boot For You!

Matt McCandless Articles, Development Technologies & Tools, Java, Spring, Spring Boot, Tutorial 1 Comment

Need a little spring in your step? Tired of all those heavy web servers and deploying WAR files? Well youโ€™re in luck.

Spring Boot takes an opinionated view of building production-ready Spring applications. Spring Boot favors convention over configuration and is designed to get you up and running as quickly as possible.

The aim of this blog is just to get you familiar with how to get Spring Boot going on your machine. It is going to be fairly straightforward and vanilla. The goal is to get you started…

Setting Up Angular 2 MockBackend

Todd Leininger Angular, Articles, Development Technologies & Tools, JavaScript, Tutorial 10 Comments

Todd was working on a client project developing one of the companyโ€™s first Angular 2 applications when he found that he needed access to the REST services before they were ready. He needed a good way to mock them up, so he set up a mock service for an Angular 2 application using MockBackend.

In this article Todd shows a step-by-step example of setting up a mock of RESTful web service APIs for an Angular 2 application using Angular’s MockBackend. With this method, he could then use that mock to work on the application before the real APIs were ready.

Using Toastr With SignalR

John Holland .NET, Articles, ASP.NET, Development Technologies & Tools, Tutorial 2 Comments

When you submit data to the server within a Single-Page Application (SPA), you are not performing the usual form post of data that would generate a new page load. Rather, you send the data using AJAX and are able to parse the response returned by the API using JavaScript and can act accordingly. In the past, this would most likely come in the form of an alert or populating a div with the appropriate message. This approach did what I needed it to do, essentially notifying the user of success or failure and allowing them to move on with their work.

Enter Toastr. Now I can have a non-blocking, consistent way in which to display these messages to the user, that are styled respective to the type of message it is. This is where the story gets interesting. So with this easy to use, non-blocking, consistent way of displaying messages, you can pair it up with SignalR and provide that same messaging from the server-side.

In this blog, we will demonstrate the use of the Toastr messaging library and how, when you couple it with SignalR, it can provide you with an easy-to-use, consistent messaging alternative.
