Beat-Aligned Mobile Audio Streaming with Virtual Chunks and Native Playback

In this article, I describe the challenges and the design of a React Native real-time mobile beat-aligned playback system for iOS and Android. The system combines personalization with low-latency, and seamless navigation and was the result of careful analysis and experimentation to address strict mobile and network constraints as well as meet user expectations.

Beyond CLEAN and MVP: Architecting an Offline-First Reactive Data Layer in Android

With the Reactive Data Layer Architecture (RDLA), you establish a clear boundary between public data APIs and private, framework-specific data-source implementations. Your presentation layer operates in a purely reactive manner, observing data changes rather than procedurally querying them. RDLA also simplifies testing by encouraging you to program to interfaces and use clean seeding patterns.

Reactive Real-Time Notifications with SSE, Spring Boot, and Redis Pub/Sub

Explore the power of reactive programming for building scalable real-time notification systems. Using Spring Boot Reactive and Spring WebFlux, leverage non-blocking operations to handle high-volume, asynchronous data flows efficiently. Discover how Redis Pub/Sub enables event-driven messaging and how the SSE protocol provides persistent connections for instant client updates without polling.

Embracing Reactive Applications on JVM: a Deep Dive into Modern I/O Models and Vert.x

This article discusses the shift from blocking to non-blocking and asynchronous I/O models, highlighting their role in modern software development. It focuses on Vert.x, a toolkit for building reactive applications on the JVM, featuring the Multi-Reactor Pattern, Event Bus, and Verticles. Vert.x is ideal for cloud, Big Data, and IoT, as shown through benchmarks and real-world examples.

Spring Boot 3.2 and Spring Framework 6.1 Add Java 21, Virtual Threads, and CRaC

Spring Framework 6.1 and Spring Boot 3.2 run on Java 21. They make concurrent programming simpler and more efficient with virtual threads, as well as improving reactive programming and Kotlin coroutines. For “Scale to Zero” startup time reduction, the OpenJDK project CRaC received initial support, while the existing GraalVM Native Image integration got faster through a GraalVM release.

Mobile Video-Conferencing Using Jitsi

In this article, we will look at alternatives for providing video meetings on mobile devices. We take Jitsi as a popular open source option, which provides Jitsi Meet, an ad-hoc video meetings service, and JaaS, a service platform for developers. Looking at user engagement data, we see there’s no "one size fits all" solution.

Exploring Architectural Concepts Building a Card Game

One of the things I missed during the pandemic were my friends, the possibility to meet them, discuss with them and, why not, play cards with them. So I decided to implement an app to play Scopone with my friends and, at the same time, test “in the code” some architectural concepts which had been intriguing me for some time.

Deep Dive into Reactive Programming with RxJS

One of the most challenging aspects of developing any user-facing application is handling asynchronous actions such as user input and API requests cleanly and robustly. RxJS helps developers author declarative code for handling side effects and asynchronous actions with continuous data streams and subscriptions.

Pathpida Brings Types to Next.js and Nuxt.js Dynamic Routing with Zero Configuration

Pathpida is a library for TypeScript projects to collect dynamic routes in one place. It is a tedious task to do manually. This helps check the existence of routes in large web apps. Pathpida is optimized for Next.js (React) and Nuxt.js (Vue). Pathpida can be added to existing Next.js and Nuxt.js projects without configuration.

Running React Applications at the Edge with Cloudflare Workers - Q&A with Josh Larson

Running web applications at the edge shortens the latency observed by users of web applications. Flareact is an edge-rendered React framework built for Cloudflare Workers and inspired by Next.js. Flareact currently supports file-based page routing, dynamic page paths, API routes, cache policy configuration, and edge-side data fetching APIs.

Brahmos, a New, Small, React-Like UI Framework with Concurrent Rendering -- Q&A with Sudhanshu Yadav

Brahmos implements the known React APIs (hooks, context, concurrent mode, and more) with a different and potentially faster method that also leverages a standard feature of JavaScript: template literals. Brahmos is among the very few UI frameworks that implements the experimental concurrent mode API sponsored by React. Other frameworks may be waiting out, or discarding the feature entirely.
