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...
The Hitchhiker's Guide to Testing Spring Boot APIs and Angular Components with WireMock, Jest, Protractor, and Travis CI
Writing apps with Spring Boot and Ionic (which is built on Angular) can be fun because both frameworks offer a good developer experience (DX). You change a file, save it, and the app automatically reloads with your changes. This feature is often called hot-reload and it’s a blissful way to develop. It’s so nice, it can cause you to forget about automating your tests. I’ll admit, writing tests is difficult to do. Writing the test...
Add Authentication to Your Xamarin App with OpenID Connect
Here at Okta we ❤️ Xamarin – it’s so much fun to build with! If you’re a Xamarin developer today, there’s a solid chance you’ll have to develop an app that requires users to sign in. Once you start doing that, you need to keep two things in mind: keep the authentication process simple for users, and keep their personal information secure. It would be nice if those things were easy, but it’s not always...
Build a CRUD App with ASP.NET Core and Angular
A lot of applications today are built with an API on the backend, and then a single page application on the front end. This is a good approach because it allows you a ton of flexibility. For example, if you get a requirement to build a native mobile client later on: it’s easy, you already have the server side in place. Today you’ll use ASP.NET Core 2.0 on the server side, and Angular 5 on...
Simple Node Authentication
Authenticating users for Node.js/Express.js web apps can be difficult. You have to set up a database, define a user schema (or use something more flexible like NoSQL), write code to handle password hashing, etc. It’s annoying. Using Okta’s API service, however, you can easily register and log in users to your Node website using our OpenID Connect integration. Note: In May 2025, the Okta Integrator Free Plan replaced Okta Developer Edition Accounts, and the Okta...
Hello, Okta. It's me, Dave
Build Server Side Authentication in Grails with OAuth 2.0 and Okta
What is Grails, what is Groovy, and why would we choose them over Spring Boot? In this post I’ll walk you through implementing server-side authentication in Grails using OAuth 2.0 and Okta. Before we dive in, however, I want to talk a little bit about why you’d be using Grails + Groovy in the first place, and how it can make your life easier in specific situations. Grails is an open source “convention over configuration”...
Use OpenID Connect for Authorization in Your ASP.NET MVC Framework 4.x App
A common practice in web applications is to have a restricted area for registered users, and perhaps another for administrators. Whether this restricted access area is premium content, or simply the order history for your e-commerce site’s users, it’s important that it be properly secured. OpenID Connect (OIDC) makes it easy, but it can be tricky to set up in ASP.NET MVC framework. In this post, I’ll show you how to create groups and use...
WebAuthn: A Developer's Guide to What's on the Horizon
There’s been a lot of news lately about the new W3C Web Authentication API, also known as WebAuthn. Want to know what it’s all about? Let’s take a closer look. The Web Authentication API allows browsers to make use of hardware authenticators such as the Yubikey or a mobile phone’s biometrics, like a thumbprint reader or facial recognition. WebAuthn can be used with these technologies to enable two-factor authentication to websites, or even as the...
Add Auth to Your PWA with Okta and Stencil
Progressive Web Applications (PWAs) are the newest technology on the web dev block and they’ve arrived just in time to solve a growing problem. Many companies are struggling to keep isolated development teams across their organization up-to-date when new features are released. Some companies are even trying to decide if it’s worth the cost to develop both a web app and a mobile application. Not surprisingly, it’s a headache most companies are looking to avoid....
