Centralize Authentication at the Gateway with Apache APISIX and OpenID Connect

Centralize Authentication at the Gateway with Apache APISIX and OpenID Connect

Apache APISIX is a dynamic, real-time, high-performance API gateway, providing rich traffic management. The project offers load balancing, dynamic upstream, canary release, circuit breaking, authentication, observability, and many useful plugins. In addition, the gateway supports dynamic plugin changes along with hot-plugging. The OpenID Connect plugin for Apache APISIX allows users to replace traditional authentication mode with centralized identity authentication mode via OpenID Connect.

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...

Web Forms Migration to Blazor in .NET Core

Web Forms Migration to Blazor in .NET Core

ASP.NET Web Forms framework has been the cornerstone technology of .Net for web development since the release of .Net Framework in 2002. ASP.NET Web Forms includes a layer of abstraction for developers so that you don’t need to care about HTML, JavaScript, or any other front-end technology. It provides a development flow similar to building desktop apps, a way for developers to build a web page by drag and drop, an event-driven programming model, and...

Content Negotiation with a Java MicroProfile Application

Content Negotiation with a Java MicroProfile Application

Content negotiation allows for an HTTP server to respond to different types of clients. Many modern clients expect a JSON response, but there may be a need to format responses differently, maybe XML for older clients or a binary format for newer ones. Content negotiation is the mechanism used to solve that problem and others, such as dealing with multiple languages and even compressing HTTP requests. In this post, I’ll walk through building a simple...

Fixing Common Problems with CORS and JavaScript

Fixing Common Problems with CORS and JavaScript

Many websites have JavaScript functions that make network requests to a server, such as a REST API. The web pages and APIs are often in different domains. This introduces security issues in that any website can request data from an API. Cross-Origin Resource Sharing (CORS) provides a solution to these issues. It became a W3C recommendation in 2014. It makes it the responsibility of the web browser to prevent unauthorized access to APIs. All modern...

How to Toggle Functionality in C# with Feature Flags

How to Toggle Functionality in C# with Feature Flags

Toggling functionality using feature flags in .NET Core apps is quite straightforward, especially with a neat little feature flag management service. In this post, I’ll walk you through how to build a simple web application using Okta for user authentication and how to use ConfigCat to manage and access feature flags. What Are Feature Flags? Feature flags (aka. feature toggles) are a relatively new software development technique that enables development teams to turn features on...
