Angular Deployment with a Side of Spring Boot
One of the more popular combinations of frontend and backend frameworks is Angular + Spring Boot. I’ve written several tutorials about how to combine the two—from keeping them as separate apps to combining them into a single artifact. But, what about deployment? Developers ask me from time-to-time, "What’s the best way to do Angular deployment?" In this tutorial, I’ll show you several options. I’ll start by showing you how to deploy a Spring Boot app...
Serverless Java with Amazon Web Services
Serverless is the next iteration in cloud management. First, we let go of having physical hardware servers and moved all of our servers into the cloud because, hey, why bother managing all that hardware? This created cloud infrastructure providers that resulted in behemoths like Amazon and Google. Now, they’re saying, why bother managing a server at all? What you really want to do is run code, right? Serverless is an architecture where code is run...
Migrate From Travis CI to GitHub Actions
Recently, a colleague pointed out that I was still configuring Travis-CI on new GitHub repos and suggested I used GitHub Actions instead. I had given Actions the ol' five-minute test when it was still in beta, but ran into a few problems and gave up. After all, I’ve been a fan of Travis-CI for a while and I had enough new things to learn at the time. Still, if GitHub Actions lives up to the...
Vue Login and Access Control the Easy Way
Vue lets you create complex and high-performance web applications. As a front-end JavaScript framework, it’s becoming more popular than ever. Vue Router is the official router for Vue. It facilitates routing in single-page applications, and provides a way to process user authentications and restrict page access. Combined with Okta, implementing secure login in a Vue app can be accomplished in a matter of minutes. User management is an important aspect of nearly all web applications,...
Whiteboarding for Developers: Yes, You Have To
I’ve always thought developers are a pretty rare collection of individuals. We all vary in our composition; from the quiet introverts to the boisterous extroverts, from button-downed professionals to aloof loose cannons – we run the full spectrum of human personalities. However, we are unique in that we share a set of common traits that are really only understood by us. Our parents might not really know what we do: “He works with computers” Our...
Build a Secure Java Application with Apache Shiro and OAuth 2.0
Apache Shiro is a Java security framework that can perform authentication, authorization, session management, along with a host of other features for building secure applications. In this tutorial, you will build a simple Java REST application using JAX-RS. JAX-RS, like many Java APIs, is a set of interfaces, and you will need to pick an implementation. For this post, I’ll use Jersey (the reference implementation of JAX-RS), but you can use Apache CXF, RESTeasy, or...
Grep for System Admins: Using Grep to Automate Daily Tasks
Photo by Lucas Sankey on Unsplash If you work with computers as a programmer or system administrator, you probably spend a lot of time staring into the command-line interface! And if you’re used to the command line, you have probably come across the grep command. So what exactly is grep? And how do I use it, and use it better? In this post, we’ll cover some of the most useful grep options and techniques to...

How to Move from Consuming Higher-Order Components to React Hooks
Let’s face it. Higher-Order Components (HOCs) allow developers to really take advantage and extend the functionality of their React components, but they can be cumbersome once you have more than one that you want to use within a component. It’s mostly because of the way they’re used. Not only do you have to use a class component in order, but you also use the HOC by wrapping them around your components. Wrapping the component code...
How to Master the Filestream in C#
We live in a world that moves fast. Compared to the mid 90s through early 2000s, we have incredibly intelligent technology. Effectively, we have super-computers in our pockets. Our actual, modern supercomputers would have seemed like works of fiction just two decades ago. Not only is our ability to compute fast, but so is our data - with cellular 4G averaging 18.1 Mbps and 5G coming in at an average of 111.8 Mbps, at the...
