    11 Non-AI Java Trends: From GraalVM to Spring Modulith

    Java developers are showcasing interest in several non-AI trends. These include GraalVM for improving runtime efficiency, Data-Oriented Programming (DOP) for treating data as first-class citizens, the debate between Quarkus and Spring Boot, in-depth details of Spring Internals, Kotlin integration with Spring Boot, and security improvements with Spring Security 3 and OAuth2. Additionally, discussions focus on the benefits of Spring Data JDBC, alternatives to Thymeleaf templates, the evolving Spring Modulith architecture, enhanced runtime efficiency with virtual threads and CRaC in Java 21, and observability improvements introduced in Spring Boot 3.2 and 3.3.

    The best way to load data in ViewModels

    Loading data into ViewModels is a complex task that involves managing states such as loading, success, and failure. A simplified and reactive approach is proposed using Kotlin's Flow and StateFlow. This method also includes handling data from memory, adding a refresh function, and dealing with side effects. The article provides a comprehensive solution with example code and a GitHub repository link for further reference.

    Comparing WebFlux and Spring MVC with JMeter, Kotlin, and Spock — A concerts registration WebApps example

    The post discusses the comparison between Spring WebFlux and Spring MVC architectures by implementing two Spring Boot applications with Kotlin and benchmarking their performances using JMeter. The WebFlux application, which follows a reactive non-blocking model, is compared to the traditional blocking MVC model. It highlights the increased capacity and performance benefits of using WebFlux, especially in handling high-load scenarios. Detailed setup instructions for JMeter and Docker configurations are provided, along with test results showing WebFlux's resilience in processing more requests compared to the MVC architecture.

    ++Android Process Lifecycle + Coroutines == ❤

    Kotlin Coroutines and Android Lifecycle complement each other effectively in Android development. By leveraging coroutines within the Android Lifecycle framework, developers can ensure tasks start and stop at the appropriate times during the app’s lifecycle, such as refreshing caches or clearing sensitive data when the app goes into the background. Examples provided demonstrate how to abstract these lifecycle-dependent tasks away from activity-specific logic, making the codebase cleaner and more robust.

    Convert Your Native Project to Kotlin Multiplatform — Developer’s Guide

    Migrating a native mobile app to Kotlin Multiplatform (KMP) allows for shared logic between Android and iOS, cutting costs and simplifying maintenance. The guide covers the technical aspects of this migration, including repository setup, modularization, dependency injection, and managing platform-specific code. It addresses common challenges and provides solutions based on extensive experience in KMP development. The process involves gradually moving Kotlin code from the Android app to a Multiplatform module, integrating it into the iOS application, and phasing out the corresponding Swift code.
