Mobile Microfrontends With Zephyr Cloud and Re.Pack | React Universe On Air #47
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.
