Super apps are becoming a practical architectural strategy for large, multi-feature mobile apps. That's why in this webinar, Callstack engineers Jakub Romańczyk, Rafał Zakrzewski, and Łukasz Chludziński walk you through how to use Re.Pack, an open-source toolkit for bundling React Native apps with Webpack and Module Federation.

You’ll learn how to build a super app architecture using the Super App Showcase—an open-source template built with Re.Pack—and explore real-world scenarios where it can help teams ship features faster, decouple release cycles, and reduce app complexity over time.

What you’ll learn about building React Native super apps with Re.Pack

If you’re struggling to manage a growing mobile codebase or looking to support multiple teams working on the same app, Re.Pack can help you break your app into smaller, independent pieces, without giving up performance or developer experience.

How Re.Pack makes super app architecture possible

• What super apps are, and how companies like Facebook and Uber use similar models.
• Why Module Federation matters for React Native development.
• How Re.Pack lets you integrate independently developed mini-apps inside one main app.
• What the open-source Super App Showcase project includes, and how to use it.

Tools and strategies for modular React Native development

• The benefits of using Webpack over Metro bundler for advanced scenarios.
• How to share libraries and dependencies across apps without conflicts.
• How to keep teams independent while maintaining a consistent user experience.
• What changes (if any) are required for mini-apps to work standalone or inside a host app.

What’s new in Re.Pack 3.2 and why it matters

• Code signing support to ensure secure delivery of remote bundles.
• Built-in support for remote assets, including automatic image scaling.
• Practical guidance for managing deployment, over-the-air updates, and App Store compliance.
• Tips for managing performance, caching, and fallback behavior.
