5 Minute Serverless Functions in Azure without an IDE

avatar-quorralyne.jpg Heather Downing

Microsoft Azure makes it incredibly easy to get a basic API/microservice up and running quickly! If you are unfamiliar with building serverless architecture in the Microsoft ecosystem, using Azure Functions has become a quick way to get back-end code up and running that is easy to understand and usable for anyone. In this tutorial, we will set-up an API endpoint using the HTTP Trigger invocation that you can use with any front-end site. I use...

Combat Side-Channel Attacks with Cross-Origin Read Blocking

avatar-tom-abbott.jpg Tom Abbott

As if developers didn’t have a big enough task securing web applications from software-layer attacks, they now have to contend with another threat: hardware-layer vulnerabilities. These complex cybersecurity flaws were introduced long before many modern developers began coding and extend from the inner workings of a computer’s silicon to a web application’s code. If exploited, hardware-layer vulnerabilities can result in leaked information from the web browser to an attacker. Luckily, Cross-Origin Read Blocking (CORB) is...

Implement the OAuth 2.0 Authorization Code with PKCE Flow

avatar-dogeared.jpg Micah Silverman

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...

Make Java Tests Groovy With Hamcrest

avatar-bdemers.jpg Brian Demers

My favorite way to test Java code is with Groovy. Specifically, writing tests in Groovy with Hamcrest. In this post, I’ll walk through how to test a simple Spring Boot application with these tools. Groovy is an optionally typed dynamic language for the JVM, and can be compiled statically. That is a mouthful and I’ll explain this as we go, but for now think of Groovy as Java with lots of sugar. Groovy is a...

Welcome, Brian Demers

avatar-bdemers.jpg Brian Demers

I’m excited to announce that I’ve joined Okta’s Developer Relations team! I’ve been working on Okta’s awesome Developer Experience team for the last couple years so I’m not exactly a new face around here. 😉 Who is Brian? As a young kid, I took things apart. Either to see how they worked or just see what was inside. This habit was made worse when I found computers and started fixing them. Anyone else miss the...

How to Work with Angular and MySQL

avatar-holger_schmitz.jpg Holger Schmitz

The MySQL database has been a reliable workhorse for web applications for many years. It is the M in the LAMP stack, and powers a huge number of web servers across the world. MySQL is also a relational database, with data stored in tables with strict data definitions. Rows in tables correspond to data entries and rows in one table can be referenced from another table through their index. Plenty of literature covers the fundamentals...

Secure an Episerver CMS website with Okta and C#

avatar-jeffhaw.jpeg Jefferson Haw

Most developers know that building an e-Commerce website can be a major pain. You have to contend with making the front end look great even when the content is dynamic and frequently updated. From seasonal themes like Black Friday and Christmas to customization based on the user’s behavior, it can be a major project to keep up. Luckily, there are platforms that allow developers to build in a templated fashion with content that can be...

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

avatar-moksamedia.jpg Andrew Hughes

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))...

Create a Blockchain Explorer in C#

avatar-terje-kolderup.jpg Terje Kolderup

Blockchain technology is already central to major cryptocurrencies like Bitcoin and its applications are ever growing. A blockchain is simply a list of records, called blocks. Each block contains information about transactions - and also confirms the validity of the previous block with something called a hash function. A hash function calculates a number from all of the data in a block. It works in such a way that if any of the bytes in...

Build a Secure React Application with JWTs and Redux

avatar-bkelley.jpg Braden Kelley

If you’ve worked with React at all, chances are you’ve at least heard of Redux. But you may not know what it is, how it fits in with React, or how to use it in your app. It can sometimes be complicated to set up but can be a very useful addition to a React app depending on your use cases. And if you’ve done much work with web apps, you also probably know how...
