Takeaways

- Over-the-air updates are a powerful feature of React Native, allowing developers to quickly patch and update their applications without going through the lengthy app review process.
- Flutter is a popular cross-platform framework, but it has limitations and is not as flexible as React Native in terms of native integration and over-the-air updates.
- Ionic and Capacitor are still relevant for certain use cases, particularly in enterprise applications and internal tools, but their importance may decrease as progressive web apps and other technologies improve.
- React Server Components offer the potential for server-side rendering and sending pre-rendered UI structures to the client, reducing the need for complex JSON-to-UI translations on the client-side.
- Mobile developers should pay attention to React Server Components as they could simplify development and improve performance by offloading rendering tasks to the server. Server components provide granular over-the-air updates and can be updated as part of a data fetch, offering a more efficient way to update components in React Native.
- The T3 stack, consisting of TypeScript, Prisma, TRPC, Tailwind, and Next.js, offers a modular and flexible solution for building full-stack applications.

In this episode, I talk with Szymon Rybczak, a 17-year-old React Native developer at Callstack. Szymon shares his journey into open source and his experience working with React Native. He discusses the benefits of contributing to open-source projects and provides tips for getting started. Szymon also explains the concept of React Server Components and how they can be used in React Native. He discusses the challenges and potential of this technology. Finally, Szymon talks about the Repack project and the future of universal apps.

Takeaways

- Contributing to open-source projects can help developers improve their skills and gain valuable experience.
- React Server Components can execute React components on a server, enabling full-stack development and performance optimizations.
- Repack is a project that allows for module federation and bundle splitting in React Native, enabling micro frontends.
- The future of React Native includes the adoption of React Server Components and the development of universal apps.

In this conversation, Kadi Kraman and I discuss various topics related to Expo and React Native. We cover EAS (Expo Application Services) and its features, including building native apps quickly and handling certificate management. We also discuss the differences between Expo Go, development builds, and pre-builds. Finally, we touch on the customization options for the Dev Client and the flexibility of transitioning from Expo to plain React Native.

Kadi also highlights the new features in Expo SDK 50, including DevTools plugins and a focus on web development. Kadi explains the benefits of Expo Router 3 and API routes, as well as the challenges of deep linking. She also mentions the future of Expo and the addition of NativeWind. Finally, Kadi shares tips for building a 5-star app, including addressing common issues and asking for positive reviews.

Takeaways

- EAS (Expo Application Services) is a CI/CD service for React Native apps that simplifies the build process and handles certificate management.
- Expo Go is a sandbox environment for testing and prototyping, while development builds allow for customization and native code changes.
- Pre-builds in Expo generate the iOS and Android directories based on the app.json and package.json files, making it easier to upgrade React Native and Expo.
- The Dev Client in Expo allows for customization of the development environment, but it is not necessary for running pre-builds. Embracing change and pivoting when things aren't working is essential for growth and success.
- Expo SDK 50 introduces new features such as DevTools plugins and a focus on web development.
- Expo Router 3 and API routes provide server-side code capabilities in React Native apps.
