Secure Secrets With Spring Cloud Config and Vault

Secure Secrets With Spring Cloud Config and Vault

In 2013, GitHub released a search feature that allows users to scan code in all public repositories. A day after the release, however, they had to partially shut it down. It was speculated that the shutdown was because the feature allowed any user to search for all kinds of secrets stored in GitHub repositories. Later, in 2014, data on 50,000 Uber drivers was stolen. It seems someone got access to the company’s database using login...

How to Prevent Reactive Java Applications from Stalling

How to Prevent Reactive Java Applications from Stalling

Modern applications must work smoothly on high loads and with a high number of concurrent users. Traditional Java applications run blocking code and a common approach for scaling is to increase the number of available threads. When latency comes into the picture, many of these additional threads sit idle, wasting resources. A different approach increases efficiency by writing asynchronous non-blocking code that lets the execution switch to another task while the asynchronous process completes. Project...

Build a Photo Gallery PWA with React, Spring Boot, and JHipster

Build a Photo Gallery PWA with React, Spring Boot, and JHipster

At its core, React is just a UI toolkit, ala GWT, but it has a very healthy ecosystem around it that provides everything you need to build a kick-ass progressive web app (PWA). PWAs are cool because if they’re done right, they can offer a native-like experience for your users, allowing them to install your app, and use it when it’s offline. But, “why React?” is what you’re probably asking yourself right now, right? Well,...

Use Ionic for JHipster to Create Mobile Apps with OIDC Authentication

We 💙 Ionic, JHipster, and Java here at Okta. Ionic is a framework for building native mobile apps using web technologies. Technically, this is called a “hybrid” app because it’s not using native SDKs. Hybrid mobile apps are distributed just like native apps: they can be installed on mobile devices, and they’re listed in app stores. As an end user, there’s a good chance you can’t tell the difference between a hybrid mobile app and...

Play Zork, Learn OAuth

In the early ’80s, some of the best “video” games were text-based adventures. These games would print out descriptive text of your surroundings and you would interact with the game using simple, but natural language commands like: “go north” or “take sword”. Fast forward some 30 years and a specification for an authorization framework called OAuth 2.0 was published. This framework allows an application to receive a token from an external party (like Okta) that...
