Defend Your SPA from Security Woes
There’s a lot of information floating out there about web security. But when I read through the material, I noticed some information wasn’t up to date, or it was written specifically for traditional server-rendered web applications, or the author recommended anti-patterns. In a series of posts, I will cover web security concerns that all web devs should be aware of, emphasizing client-side applications, namely Single Page Applications (SPAs). Furthermore, I’m not going to get into...
Build a React App with Firebase Serverless Functions
Firebase is an exciting cloud platform from Google available to businesses today. Firebase connects everything from simple static websites to IoT devices to AI and machine learning platforms. The platform provides various services to facilitate these connections, like storage and authentication. In this tutorial, you will learn about two core Firebase products: Cloud Functions for Firebase and Firebase Hosting. Hosting is for deploying static web applications. Functions are the Firebase serverless platform. You will create...
How to Deploy Java Microservices on Amazon EKS Using Terraform and Kubernetes
When it comes to infrastructure, public clouds are the most popular choice these days, especially Amazon Web Services (AWS). If you are in one of those lucky or unlucky (depending on how you see it) teams running microservices, then you need a way to orchestrate their deployments. When it comes to orchestrating microservices, Kubernetes is the de-facto choice. Most public cloud providers also provide managed Kubernetes as a service; for example, Google provides Google Kubernetes...
Use React and Spring Boot to Build a Simple CRUD App
React was designed to make it painless to create interactive UIs. Its state management is efficient and only updates components when your data changes. Component logic is written in JavaScript, meaning you can keep state out of the DOM and create encapsulated components. Developers like CRUD (create, read, update, and delete) apps because they show a lot of the base functionality you need when creating an app. Once you have the basics of CRUD completed...
OAuth for Java Developers
You can use OAuth to secure apps, APIs, and devices. OAuth has become increasingly popular, especially as developers are asked to knit together hundreds of apps and thousands of users in enterprise environments. The Java ecosystem is vast, with over 10 million developers worldwide and an abundance of IDEs, build tools, libraries, and frameworks to make them more productive. The infographic below is recommended as a starting point for Java developers. It’s designed to help...
How to Secure User Data in Azure Cosmos DB
Cosmos DB is a cloud database product from Microsoft that offers scalable and high-performance services. The core product runs on a proprietary NoSQL database that should look familiar to experienced MongoDB developers. Microsoft offers several APIs in addition to the core Cosmos DB API. These include APIs for: SQL MongoDB Gremlin Cassandra The shift to serverless database operations is one of the most obvious advantages of migrating. Cosmos DB can automatically scale your throughput based...
Cloud Native Java Microservices with JHipster and Istio
Microservices are not everyone’s cup of tea, and they shouldn’t be. Not every problem can or should be solved by microservices. Sometimes building a simple monolith is a far better option. Microservices are solutions for use cases where scale and scalability are important. A few years ago, microservices were all the rage, made popular, especially by companies like Netflix, Spotify, Google, etc. While the hype has died down a bit, genuine use cases still exist....
Run Microservices on DigitalOcean with Kubernetes
Cloud adoption continues to increase rapidly worldwide, and not only in the software industry. Every year more and more companies move their applications to the cloud. In the last JHipster community survey, from December 2021, participants valued JHipster’s ability to get them to production faster, and requested more tutorials on deployment to cloud platforms. DigitalOcean is among the most popular “other” cloud vendors, according to some surveys. This post is a quick walk-through of the...
Create a Java REST API with Helidon
In this tutorial, I’ll show you how to create a secure REST API and native image with Helidon. You’ll see how to run a secure, OAuth 2.0-protected, Java REST API that allows JWT authentication. Then, I’ll compare its performance with Micronaut, Quarkus, and Spring Boot. This tutorial is also available as a screencast. Prerequisites: SDKMAN (for Java 17 with GraalVM) HTTPie (a better version of cURL) An Okta Developer Account (or the Okta CLI) The...
The Identity of OAuth Public Clients
I recently got back from a series of events filled with lots of interesting discussions around various OAuth-related topics. At the official IETF meeting in Vienna back in March, I presented the latest work on OAuth 2.1 and we discussed and made progress on some of the current open issues. At the OAuth Security Workshop a few weeks later, I presented a session on client authentication for mobile apps, and there were many more presentations...
