Build a CRUD App with ASP.NET Core 2.2 and Entity Framework Core

LiveMusicFinder is a web application that allows users to enter when and where some live music is going down. This beta version is very rough, but I will show you how I built it with...
Build a Microservice Architecture with Spring Boot and Kubernetes
In this tutorial, you’re going to use Kubernetes to deploy a Spring Boot microservice architecture to Google Cloud, specifically the Google Kubernetes Engine (GKE). You’re also going to use Istio to create a service mesh layer and to create a public gateway. The whole thing is going to be secured using Okta OAuth JWT authentication. That was a mess of jargon. We’re not going to explain microservices in-depth here. In short, microservices are a design...
Test Your Spring Boot Applications with JUnit 5
In this post, you’ll walk through how to build a simple Spring Boot application and test it with Junit 5. An application without testing is the proverbial Pandora’s Box. What good is your application if you don’t know that it will work under any condition? Adding a suite of tests builds confidence that your application can handle anything thrown at it. When building your tests, it is important to use a modern and comprehensive suite...

Build a CRUD App with ASP.NET Core and TypeScript
There are a lot of things for .NET developers to love about TypeScript. It has strong typing that .NET Developers are used to and the ability to use the latest JavaScript features. Since it is just a superset of JavaScript, the cost to switch is almost nothing. Getting Visual Studio to transpile the TypeScript when it builds your ASP.NET Core app is pretty simple as well. In this tutorial, you will build an ASP.NET Core...

Build Secure Microservices with AWS Lambda and ASP.NET Core
Microservices are fun to build and offer us a scalable path to overcoming problems with tightly coupled dependencies that plague monolithic applications. This post will walk you through building an AWS Lambda microservice written in C# with .NET Core 2.1, and communicating in JSON. We’re bringing together multiple exciting technologies here - microservices, serverless API via AWS Lambda, and authentication using Okta’s easy and convenient identity provider. Each of these technologies is deserving of their...
Linking Your Alexa Skill Securely with Okta

From a gesture-driven by an actual human being to automated interactions from another device or application, a lot of developers and even non-computer savvy users are trying to explore this space. In this post, I will use Amazon’s Alexa which is Amazon’s voice-enabled and command Virtual Assistant as an example. I’ll show how you can make...
Build a Desktop Application with Angular and Electron
So, you have been learning all about web technologies including JavaScript, HTML, and CSS. The advantage of web technologies is, of course, that the same software can be used on many different platforms. But this advantage comes with a number of problems. Web applications have to be run inside a browser and the interoperability with the operating system is limited. Direct access to features of the operating system is usually the domain for desktop applications....
