Spring Makes Java Better!

-

     Spring is a very popular Java framework that makes working with Java applications easy. It provides dependency injection using the beans, and it also contains other modules for MVC, Web Development, messaging and more. Spring is a lot of things, and although when I first saw it on countless job postings I assumed it was just for building REST API's, but it is for so much more than that. I just finished watching an excellent PluralSight video by Bryan Hansen that covers the basics of Spring, and we didn't even begin to cover how to build a REST API. Still, I completely understand why Spring is so useful in building large applications. 

     Spring cuts out the clutter and makes your code more business-focused. You can make Beans, which are kind of like components, and you can tell them what to be and what to do. For example, Beans default to singleton (unless you'd rather they be a prototype) so when you want to create an instance of an object, you only create one, without having to write a bunch of code to make it a singleton! Spring is a handy way of removing boiler-plate code, and it makes your code more easily testable. 

    You can see from these images that we have wired this Service component to be initialized so that when we create the service we can access the findAll() function initialize our speaker object. This way we don't need several lines of code to to tell our SpeakerService to be an instance of Speaker.

    I'm only getting started with Spring, but it reminds me a lot of ASP.NET, and I can absolutely see how it would be a fantastic way to organize your project. You can check out the code here! There is a method of using Spring in Java, XML and one without to compare.

API's in C#

      There is a lot here to take screen shots, but the code is all on my GitHub here if you'd like to follow along with this post.       My wife teaches sixth grade, and lately I've been thinking about an application I could build her to help manager her classroom and motivate the students to improve on the skills they've been struggling with. The concept is to turn a classroom into a game of Dungeons & Dragons, except the skills are in things like math and reading. Students would answer questions instead of rolling dice, and can then add their skills to their results so they can earn experience and rewards. Originally I was going to build this in FastAPI but I thought .NET Core would be better for setting up models and working with a database.     I started by setting up my models in a shared class library project, and I added a Classroom class for tracking classes of students, a Student class for tracking the stats of students and a Logs class to keep track of how a

Using WebRTC to build a videophone in React and TypeScript

-
 Recently I had the opportunity to spend more time learning React, as well as Redux and a bit about WebRTC. I was prototyping a website that allows you to make video calls to other users, and I thought it was really cool how out-of-the-box WebRTC is. I also used TypeScript, even though I had some trouble in the past with React-TypeScript applications, and it went pretty well. There was some finicky things and it required me to learn the types of objects I had never used before, but overall I think it went pretty well.   The server is built with express, and uses socket.io to emit the web-rtc requests. There is no authentication or authorization, I was mainly focused on showing that I could make a video call.It uses Redux to handle state management, which was a bit tricky in TypeScript and felt like I was writing a lot of repeat code, but it got the job done better than it would have without it. Ultimately this project ended up being put on the backburner as my team turned to Flutter in

Reviewing WPF and MVVM

 I've been working in WPF (Windows Presentation Foundation) a lot lately. WPF is a great way to build a Windows desktop application, it's been around for many years and is very mature compared to UWP (Universal Windows Platform) which is a similar tool for creating desktop applications. It's not the newest, shiniest tool but it is definitely a great tool to be aware of. A while back I built a simple WPF program that worked with a .NET function library that did very simple distance calculations, and I decided to review that before really getting into more advanced concepts. When the program runs, it looks like this:   It's nothing too fancy, but it will show travel time, rate of travel and distance traveled over time. It also allows an excel spreadsheet to be inputted and it will run many calculations and then update the spreadsheet. The layout here is primarily built using the XAML grid, a staple of any WPF application. The grid specifies how many rows and columns the g
