Build a Simple Web App with Express, Angular, and GraphQL
During the past 10 years or so, the concept of REST APIs for web services has become the bread and butter for most web developers. Recently a new concept has emerged, GraphQL. GraphQL is a query language that was invented by Facebook and released to the public in 2015. During the last three years, it has created quite a stir. Some regard it as a new revolutionary way of creating web APIs. The main difference...
Build and Test a React Native App with TypeScript and OAuth 2.0
React Native is one of the most popular ways of creating mobile apps. Building on the success of React, it ties together native components for both Android and iOS using a shared JavaScript code-base. However, JavaScript has come under fire recently for not being type safe which can lead to a loss of developer trust. Enter TypeScript, which allows type annotations to be added to existing JavaScript code. One requirement of many mobile apps is...
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...
Spring Boot 2.1: Outstanding OIDC, OAuth 2.0, and Reactive API Support
Spring Boot 2.1 was recently released, eight months after the huge launch of Spring Boot 2.0. The reason I’m most excited about Spring Boot 2.1 to me is its improved performance and OpenID Connect (OIDC) support from Spring Security 5.1. The combination of Spring Boot and Spring Security has provided excellent OAuth 2.0 support for years, and making OIDC a first-class citizen simplifies its configuration quite a bit. For those that aren’t aware, OIDC is...

Use TypeScript to Build a Node API with Express
Like it or not, JavaScript has been helping developers power the Internet since 1995. In that time, JavaScript usage has grown from small user experience enhancements to complex full-stack applications using Node.js on the server and one of many frameworks on the client such as Angular, React, or Vue. Today, building JavaScript applications at scale remains a challenge. More and more teams are turning to TypeScript to supplement their JavaScript projects. Node.js server applications can...

Tutorial: Create and Verify JWTs in Java
Java support for JWT (JSON Web Tokens) used to require a lot of work: extensive customization, hours lost resolving dependencies, and pages of code just to assemble a simple JWT. Not anymore! This tutorial will show you how to use an existing JWT library to do two things: Generate a JWT Decode and verify a JWT You’ll notice the tutorial is pretty short. That’s because it’s that easy. If you’d like to dig deeper, take...
Add Secure Authentication to your WordPress Site in 15 Minutes
Do you run a WordPress site and want to avoid managing a separate list of user accounts? Have you ever wanted to add two-factor authentication to WordPress? Typically WordPress keeps its own database of usernames and passwords, but if you run multiple websites, I’m sure you’re familiar with the pain of keeping lists of users in sync. Wouldn’t it be great if you could manage all your users in one place, letting them log in...
