Reanimated 4 is the Future of Smooth React Native Animations | React Universe On Air #48 49:28

πριν 12 μέρες49:28

49:28

Reanimated 4 is here to change the way we build animations in React Native. With CSS-style animations and transitions, animations are now easier to write, more predictable, and work more like they do on the web. In this episode, Ola Desmurs-Linczewska (https://x.com/p_syche_) sits down with Tomasz Zawadzki (https://x.com/tomekzaw_) and Mateusz Łopaciński (https://x.com/MatiPl01) from Software Mansion to discuss what’s new in Reanimated 4, why React Native is moving toward web standards, and what these changes mean for developers. We talk about: 💜 Why Reanimated 4?—the motivation behind CSS-based animations and what problems they solve. 💜 How CSS animations & transitions work in React Native—use the syntax you already know! 💜 New Architecture-only support—why the old architecture is gone and what it means for migration. 💜 Aligning React Native with web standards—how Meta and the community are making React Native more like the web. 💜 Modularity and the future of Reanimated—splitting the library into smaller packages for better maintainability. 💜 Migration tips and developer experiments—how to upgrade, test new features, and start using CSS animations today. Reanimated 4 is in beta now, so experiment with it and share your impressions in the comments!

Picture this: your teams are innovating independently, deploying updates swiftly, and navigating complex app architectures with ease. Microfrontends make this possible, much like microservices revolutionized backend development. But what about mobile? How can this approach transform your app development strategy? To explore these questions, we’re joined by Zack Chapple (https://x.com/Zackary_Chapple ), Co-founder and CEO of Zephyr Cloud, and Jakub Romańczyk (https://x.com/_jbroma ), maintainer of Re.Pack at Callstack. They dive into the evolution of microfrontends, starting with the fundamentals: what they are, why they matter, and how technologies like Module Federation enable them. Zack shares insights on tools like Webpack, Rspack, and Zephyr Cloud, showing how they streamline managing complex frontends. The episode then shifts focus to mobile, where Zack and Jakub break down the Zephyr Cloud and Re.Pack collaboration. Learn how to tackle platform-specific challenges like managing version compatibility, over-the-air updates, and reducing bundle sizes—all while staying app store compliant. Plus, hear about real-world scenarios, like dynamically loading features or ejecting unused code to optimize performance, and get a sneak peek at Re.Pack 5.

Lessons from Shopify's Migration to React Native with Mustafa Ali | React Universe On Air #46 42:15

πριν 7 weeks42:15

42:15

In 2020, Shopify decided to switch to React Native for both new and existing apps. In November 2024, the migration of their mobile app was officially over, resulting in a remarkable 86% unification of code across platforms and a streamlined development process that stems from eliminating 1.8 million lines of redundant code, reducing build times, and achieving seamless feature parity between iOS and Android. Let’s take a closer look at the decision-making process involved in this transformation with Mike Grabowski (@grabbou at X) as our host and Mustafa Ali (@mustafa01ali at X), Shopify's Director of Engineering, as his guest. Learn about the motivations for this change, such as reducing duplicated efforts and enabling seamless developer collaboration across web and mobile, the challenges faced, particularly in optimizing performance for their high-usage point-of-sale app, and the essential role of native developers in ensuring exceptional app performance and user experience.

In this episode, we’re taking a closer look at two solutions that can redefine how we build universal React Native apps: DOM Components and React Server Components. They promise faster and better development—think low-latency interactions, offline capabilities, and the flexibility to scale effortlessly. If you're looking to future-proof your team's workflow and deliver apps that delight users regardless of the platform, this is a must-listen. To discuss DOM & React Server Components in detail, Łukasz invited Evan Bacon, the creator of Expo Router and Engineering Manager at Expo. Throughout the episode, Evan shares his expertise and journey in creating tools like DOM Components, which enable developers to integrate web code seamlessly into React Native apps, and React Server Components, simplifying server-driven rendering for mobile applications.

What is this, a crossover episode? You bet! React Universe On Air is joining forces with React Native Radio once again to help you navigate App Center’s retirement. In March 2024, Microsoft announced the sunset of App Center in 12 months. Bearing in mind how big of a deal CodePush is for React Native applications, it’s a radical change for developers and businesses alike. We’re releasing this episode six months before it actually takes place because it’s high time you started planning migration (if you haven’t already). In this episode, we discuss the impact of App Center's sunsetting on businesses, explore the best alternatives, and provide actionable insights on how to prepare for the transition. And since our focus is the React Native ecosystem, Łukasz Chludziński and Mazen Chami invited a very special guest: Quinlan Jung from Expo. Together, they talk about: 💜 the meaning of App Center retirement 💜 community reception of this piece of news 💜 most frequently used App Center’s functionalities and their replacements 💜 how Expo Application Services fit the picture 💜 migration tips for businesses, especially enterprises Check out episode resources on our website 🧠 https://hubs.li/Q02Vr44t0 Share your feedback on this episode ✨ https://bit.ly/ep43feedback Check out other episodes of our podcast 🎧 https://hubs.li/Q02VgpsK0 Sign up to receive curated content for tech leaders and developers ✉️ https://hubs.li/Q02Vgpsd0 Follow us on Twitter 🐦 https://twitter.com/callstackio…
