Test Your GitHub Repositories with Docker in 5 Minutes

avatar-pmcdowell.jpg Patrick McDowell

How many times have you checked your code into GitHub, just to have someone else check it out and find out there was some dependency missing so they could not get it to run? I rely heavily on Docker for my build environment, and before I release anything to a teammate, I like to run it through a quick test in Docker to make sure everything is working properly. This approach is simple and only...

Build a Simple API Service with Express and GraphQL

avatar-bkelley.jpg Braden Kelley

GraphQL has become an immensely popular alternative to REST APIs. The flexibility you get from using GraphQL makes it easier for developers to get any information they need for an app, and just the information they need for that portion of the app. That gives you the feel of a very customized API and can help cut down on bandwidth. In this tutorial, I’ll show you how to write a custom GraphQL API using Node...

Build a Web App with Spring Boot and Spring Security in 15 Minutes

avatar-moksamedia.jpg Andrew Hughes

Developers know that securing web apps can be a pain. Doing it right is tough. The worst part is that “right” is a moving target. Security protocols change. Vulnerabilities are found in dependencies and patches are released. Tons of often complex boilerplate code has to be generated. The software-as-service paradigm has proliferated over the last decade, and while I love reinventing the wheel as much as the next developer (because, clearly, I’m gonna write it...

Full Stack Reactive with Spring WebFlux, WebSockets, and React

avatar-matt_raible.jpg Matt Raible

Spring WebFlux can be used to create a REST API with streaming data. Spring WebFlux can also be integrated with WebSockets to provide notifications that clients can listen to. Combining the two is a powerful way to provide real-time data streaming to JavaScript or mobile clients. Add React to the mix and you have an excellent foundation for a full-stack reactive architecture. React is a UI toolkit (similar to GWT) that lets you build components...

Spring WebFlux is a web framework that’s built on top of Project Reactor, to give you asynchronous I/O, and allow your application to perform better. If you’re familiar with Spring MVC and building REST APIs, you’ll enjoy Spring WebFlux. There’s just a few basic concepts that are different. Once...

Get Started with Reactive Programming in Spring

avatar-matt_raible.jpg Matt Raible

Reactive programming allows you to build systems that are resilient to high load. Handling lots of traffic isn’t a problem because the server is non-blocking and doesn’t block client processes to wait for responses. The client cannot directly observe, or synchronize with, the execution that occurs on the server. When an API is struggling to handle requests, it should respond in a sensible way. It shouldn’t fail to work or drop messages in an uncontrolled...

Build a Desktop App with Electron and Authentication

avatar-matt_raible.jpg Matt Raible

Electron is a framework for building cross-platform desktop applications with web technologies like JavaScript, HTML, and CSS. It was created for GitHub’s Atom editor and has achieved widespread adoption since. Electron powers several apps that I use on a daily basis: Slack, Kitematic, and Visual Studio Code to name a few. Electron 2.0 was released in early May 2018, along with changes to the project to adhere to strict semantic versioning. This is good news...

Build and Understand Express Middleware through Examples

avatar-leebrandt.jpg Lee Brandt

If you’ve done any significant Node development in the past seven or eight years, you’ve probably used Express to build a web server at some point. While you can create a server in Node without using a library, it doesn’t give you a lot out of the box and can be quite cumbersome to add functionality. Express is a minimalist, “unopinionated” server library and has become the de facto standard for building web apps in...
