Build a CRUD App with Vue.js, Spring Boot, and Kotlin

Build a CRUD App with Vue.js, Spring Boot, and Kotlin

Much like React or Angular, Vue.js is a JavaScript view library. When coupled with a state management library like MobX, Vue.js becomes a full-featured application framework. Vue.js is designed to be incrementally adoptable, so you can use as much or as little of it as you like. Like React, Vue.js utilizes a virtual DOM to streamline processing so that it renders as little as possible on each state update. In my experience, Vue is far...

Build a Secure REST Application Using Jersey

Build a Secure REST Application Using Jersey

REST is one of the most used architectural styles when it comes to developing web services. In Java, we have the JAX-RS specification that defines how to create a RESTful application. To show the power of the spec, Jersey, the reference implementation of JAX-RS was created. Building JAX-RS endpoints only requires adding annotations to your code. Keep reading to see how easy it is!

Watch GraalVM Turn Your Java Into Binaries

Watch GraalVM Turn Your Java Into Binaries

There has been much buzz about GraalVM and what it means for the Java world. GraalVM is a Java distribution from Oracle that adds a bunch of features, most notably a new JIT compiler, polyglot capabilities, an LLVM runtime… and the ability to turn your Java application into a native binary. This last one offers the potential to distribute Java applications as a single binary, and a few frameworks like Quarkus, Helidon, and Micronaut already...

How to Create a Simple Symfony Application with Authentication

How to Create a Simple Symfony Application with Authentication

Symfony is not the most popular or loved PHP framework, but it’s arguably the most mature, flexible, and reliable. Since its initial release, Symfony has evolved into a set of loosely-coupled, high-quality components that can be chosen individually or combined to create powerful applications, without the compromise of bloat or huge runtime overhead. These components are also widely used outside the context of the framework, as stand-alone modules or sitting at the bottom of other...

How to Build a Maven Plugin

How to Build a Maven Plugin

Apache Maven is still the most popular build tool in the Java space, thanks to the popularity of its ecosystem of plugins. It’s easy to find an existing plugin to do almost anything your application needs, from ensuring your source files have license headers, to validating binary compatibility between versions. Occasionally though, you need to write a custom plugin to fulfill a requirement in your product. In this tutorial, I’m going to show you how...

Get Groovy with Gradle

Get Groovy with Gradle

In the Java world, there are two main build systems: Gradle and Maven. A build system chiefly manages potentially complex webs of dependencies and compiles the project. It also packages the compiled project along with all the resources and meta files into the final .war or .jar file. For simple builds, the choice between Maven and Gradle is pretty much one of personal taste, or perhaps the taste of your CTO or technical manager. They...

Implement the OAuth 2.0 Authorization Code with PKCE Flow

Implement the OAuth 2.0 Authorization Code with PKCE Flow

Imagine two levers that are inversely connected. That is, as one goes up, the other goes down. One lever is User Experience and the other is Security. It’s not a perfect analogy, but most developers can attest that as user experience goes up, security goes down. Take browser history syncing for example. I can start a session with my bank on Firefox mobile and pick up right where I left off on Firefox desktop. From...

Tutorial: How to Build a JavaFX Desktop App with OIDC Authentication

Tutorial: How to Build a JavaFX Desktop App with OIDC Authentication

JavaFX, a library of user interaction controls, allows Java developers to build cross-platform desktop applications and internet application. It was intended as a replacement for Swing (if you’re old like me and remember that). Implementing an authorization flow with OAuth 2.0 can be tricky with a desktop framework like JavaFX. Typically, OAuth flows require a browser and redirecting to specific URLs. Detecting a redirect in JavaFX’s default browser is impossible. The default Java browser (java.awt.Desktop.browse(URI))...

Use Azure Cosmos DB with Your ASP.NET App

Use Azure Cosmos DB with Your ASP.NET App

Cosmos DB is a planet-scale database capable of holding billions of records (“documents” using Cosmos jargon) without significant detriment to performance. In this article, you will learn how to use Azure Cosmos DB - a key-value store solution - your ASP.NET app instead of a relational database. To demonstrate their differences, check out a simple example query using both a relational database and Cosmos DB. When you query a relational database you get back a...

Build a Simple CRUD App with Python, Flask, and React

Build a Simple CRUD App with Python, Flask, and React

Today’s modern web applications are often built with a server-side language serving data via an API and a front-end javascript framework that presents the data in an easy-to-use manner to the end user. Python is a dynamic language widely adopted by companies and developers. The language states on its core values that software should simple, readable making developers more productive and happier. You’ll also use Flask to help you to quickly put together a ReST...

Build Your First Router in Node with Express

Build Your First Router in Node with Express

If you’ve done any web development with Node in the last few years, you’ve probably used Express. Even if you haven’t used it directly, many frameworks meant to make web development even simpler are still built on Express. One of the key features in Express is the ability to create routes. An infinite combination of URLs can hit the same Express server, and routes are how you can determine which URLs run what piece of...

Build a Video Chat Service with JavaScript, WebRTC, and Okta

As recently as seven short years ago, building video applications on the web was a massive pain. Remember the days of using Flash and proprietary codecs (which often required licensing)? Yuck. In the last few years, video chat technology has dramatically improved and Flash is no longer required. Today, the video chat landscape is much simpler thanks to WebRTC: an open source project built and maintained by Google, Mozilla, Opera, and others. WebRTC allows you...
