Microfrontends make this possible, enabling the decomposition of frontends, much like microservices transformed backend development. But how does this translate to the mobile app development landscape? And what does it mean for your team’s velocity and strategy? To give you the answers, we invited Zack Chapple, the Co-founder and CEO of Zephyr Cloud, and Jakub Romańczyk, the maintainer of Re.Pack at Callstack to talk about the evolution of microfrontends and their adaptation to mobile development.  ## How to embrace microfrontends on mobile? Our episode starts with the fundamentals: what microfrontends are, why they matter, and the technical enablers that make them possible (Module Federation, anyone?). To give you a better understanding of this concept, Zack draws parallels between microservices and frontend decomposition, explaining how this approach empowers teams to ship independently while maintaining alignment with organizational goals. Then, we proceed to discuss the role of Webpack, Rspack, and Zephyr Cloud, showing how each of these solutions streamlines the management of complex frontends on web. And since we were to talk about mobile microfrontends, that’s where the Zephyr Cloud and [Re.Pack](https://www.callstack.com/open-source/re-pack) collaboration steps in. In addition to explaining how the integration of these tools works, our guests cover platform-specific pain points, such as managing version compatibility across shell apps and federated modules and dealing with over-the-air updates while staying compliant with app store regulations. They also explore real-world scenarios, including reducing bundle sizes, dynamically loading features based on user needs, and even ejecting unused code to optimize app performance. And let’s not forget a teaser for the Re.Pack 5 release! ## Why should you care about mobile microfrontends? For engineering teams, adopting microfrontends means smoother collaboration, faster development cycles, and reduced risk when rolling out updates. Organizations benefit from more agile workflows, streamlined app maintenance, and the ability to scale effectively without sacrificing quality or speed. This is by no means one solution to fit all, but if your team is grappling with massive app architectures or looking to innovate with smaller, more nimble components, this episode offers some tips for success. ## More about microfrontends with Zephyr Cloud and Re.Pack - [Zephyr Cloud’s website](https://www.zephyr-cloud.io/) - [Zack Chapple on X](https://x.com/Zackary_Chapple) - [Re.Pack on GitHub](https://github.com/callstack/repack) - [Jakub Romańczyk on X](https://x.com/_jbroma) - Michael Geer’s [book on Microfrontends](https://the-tractor.store/) Insights ## Learn more about Super Apps Here's everything we published recently on this topic.
