Michael Hladky joins the pod to explain how CSS performance improvements like content-visibility, CSS containment, contain layout, and contain paint can dramatically outperform JavaScript virtual scrolling. The conversation explores virtual scrolling, large DOM performance, and how layout and paint work inside the browser rendering pipeline, including recalculate styles and their impact on INP Interaction to Next Paint. Michael shares real-world examples of frontend performance optimization, discusses cross-browser CSS support including Safari content-visibility, and explains why web performance issues tied to rendering are often misunderstood and overlooked.

In this episode of PodRocket, Daniel Thompson--Yvetot joins us to break down what’s new in Tauri 2.0 and how developers are using the Tauri framework to build desktop and mobile apps with Rust and JavaScript. We discuss how Tauri lets developers use frameworks like React, Vue, and Angular for the UI while handling heavy logic in Rust, resulting in smaller app binaries and better performance than Electron alternatives. The conversation covers Create Tauri App for faster onboarding, the new plugin system for controlling file system and OS access, and how Tauri improves app security by reducing attack surfaces. They also dive into mobile app development, differences between system WebViews, experiments with Chromium Embedded Framework, and why cross platform apps still need platform-specific thinking. Daniel also shares what’s coming next for Tauri, including flexibility in webviews, accessibility tooling, compliance requirements in Europe, and the roadmap toward Tauri 3.0.
