    React Native at Scale With NFL

    The NFL runs on tight deadlines. Every kickoff and Super Bowl demands that millions of fans get flawless live video, stats, and fantasy features, whether they’re on iPhones, Xboxes, or connected TVs. In this episode of React Universe On Air, Mike Grabowski talks with Michael Blanchard (Director of Engineering at the NFL), about how React Native became the backbone of this high-pressure, multi-platform ecosystem. Michael shares his journey from web engineer to leading NFL’s engineering teams across nfl.com, three mobile apps, a cross-platform video player, and a suite of connected TV apps. Together with Mike, he explores the NFL’s migration strategy, the transition from Haul/Webpack to Metro and Expo, and the cultural shifts that helped merge web and native engineers into one collaborative team. You’ll learn: ➡️ Why the NFL went full Greenfield (twice) ➡️ How NFL+ shaped their second rewrite ➡️ Lessons from moving from Haul/Webpack to Metro ➡️ How Expo SDKs gradually replaced community libraries ➡️ How GitHub Actions + EAS Build reshaped their CI/CD pipeline ➡️ Strategies for handling 20–30 PRs daily in a monorepo ➡️ How React Native powers mobile, web, and multiple connected TVs ➡️ What cultural shifts enabled true cross-platform collaboration Catch more React Universe On Air episodes 🎧 https://clstk.com/4gp8Cw5 Sign up for our newsletter ✉️ https://clstk.com/4mfmRof Follow us on X 🐦 https://x.com/callstackio Chapters: 00:00 Welcome to the React Universe 01:35 Meet Michael Blanchard from NFL 03:03 NFL's digital presence and platforms 04:24 React Native in NFL's mobile apps 08:32 How React spread across all platforms 11:47 Collaboration between web and native teams 18:11 Technical decisions regarding different platforms 23:48 V2 of NFL's flagship app 25:14 Choosing migration strategy 30:10 Maintaining more product versions 34:33 Adopting Expo 42:10 Modernizing CI/CD 46:48 Team structure and workflow at NFL 53:29 Final thoughts

    Observability & OpenTelemetry in React Native

    Many React Native apps ship without full observability. The result? Blind spots in performance, crashes, and user behavior once your app is in the wild. In this episode of React Universe On Air, Łukasz Chludziński sits down with Jonathan Munz (Senior Software Engineer at Embrace) and Adam Horodyski (React Native Expert at Callstack) to unpack how OpenTelemetry can bring structure and clarity to mobile monitoring. They break down why mobile observability is harder than observability on backend, what the OTLP protocol enables, and how to instrument React Native apps without locking into a single vendor. You’ll also hear how community-driven tooling like React Native OpenTelemetry and the Embrace React Native SDK can simplify setup and improve data portability. You’ll learn: ➡️ How observability and OpenTelemetry work together ➡️ The 3 core OpenTelemetry signal types for mobile ➡️ Why mobile instrumentation is more complex than backend telemetry ➡️ How OTLP improves interoperability between tools ➡️ Where auto-instrumentation is still missing in React Native ➡️ The role of Embrace and open-source libraries in reducing setup overhead Check out episode resources on our website 📚 https://clstk.com/4104nAF Catch more React Universe On Air episodes 🎧 https://clstk.com/45EWnYe Monitor what matters in your React Native app with Callstack’s help 🤝 https://clstk.com/3HoM3KI Sign up for our newsletter ✉️ https://www.callstack.com/newsletter Follow us on X 🐦 https://x.com/callstackio Chapters 00:00 Welcome to the React Universe 01:07 Meet our guests 03:07 Defining observability and OpenTelemetry 04:32 Signals in observability 11:57 Challenges with observability in React & React Native 16:04 Standardization and OpenTelemetry protocol 18:08 Embrace and Open Telemetry 21:29 Future of OpenTelemetry in mobile 27:23 Exploring React Native OpenTelemetry 29:54 Community involvement in OpenTelemetry 37:34 Real observability in React Native 46:41 Future of React Native observability 50:40 Hey, listeners, here’s what we want you to do 54:46 Conclusion and final thoughts

    From 30min to 3min Build Times With React Native Enterprise Framework

    What if you could skip most native builds—and still ship confidently? In this episode of React Universe On Air, we explore how the React Native Enterprise Framework (RNEF) helps large teams dramatically reduce build times and streamline development at scale. Our guest Michał Pierzchała, Principal Engineer at Callstack, shares how RNEF was built to solve real-world bottlenecks in enterprise React Native projects. Alongside him, Łukasz Chludziński discusses his experience testing the framework in a live production environment, where build times dropped from 35 minutes to just 3. What you'll learn: - How RNEF slashes native build times with CI-based caching - Ways to adopt the framework incrementally—no full rewrite required - How brownfield support lets you drop React Native into native apps easily - What makes RNEF different from Expo and Community CLI - Real-world savings and improved developer-QA workflows Check out episode resources on our website 📚 https://clstk.com/4e5OL3W Explore React Native Enterprise Framework ✨ https://clstk.com/4kAt7ap Catch more React Universe On Air episodes 🎧 https://clstk.com/3SJRk1G Get 20x faster builds on your CI in less than a week with our help 👉 https://clstk.com/3ZWJ9Tq Sign up for our New York meetup in June 2025 👉 https://clstk.com/4kEyG7C Follow us on X 🐦 https://x.com/callstackio 00:00 Welcome to the React Universe 01:07 Host & guest introductions 02:40 Project overview: React Native Enterprise Framework 04:04 Challenges in large repositories 04:50 Testing and build time optimization 07:31 Building RNEF on a real-life use case 12:37 Integrating RNEF POC to the project 15:00 Incremental adoption mindset 21:42 What it all has to do with React Native Community CLI 26:05 Optimizing build process with smart caching 44:06 Seamless collaboration between devs & QA 47:28 Brownfield projects with RNEF 55:50 Where RNEF stands in the ecosystem 59:08 What does it mean to be a React Native framework?

    You Don’t Need a Rewrite, You Need React Native Brownfield | React Universe On Air Coffee Talk #27

    Is rewriting your native app really the only way to go cross-platform? In this Coffee Talk episode, we explore how React Native Brownfield offers a smarter path forward. Łukasz Chludziński invites Oskar Kwaśniewski and Burak Güner—who work directly on React Native Core and brownfield tooling—to discuss how recent advances in React Native have made brownfield integration far more viable, stable, and scalable. You’ll learn: ➡️ Why brownfield isn’t what it used to be (goodbye, brittle bridging) ➡️ How `RootViewFactory` and `ReactNativeFactory` APIs simplify setup ➡️ What’s new in React Native Brownfield 1.0.0 ➡️ How to keep your architecture clean while integrating React Native ➡️ What this means for modern native stacks like SwiftUI, Jetpack Compose—and future-facing platforms like visionOS Whether you’re maintaining a legacy app or building for what's next, this episode gives you a blueprint for hybrid success.

    TanStack Ecosystem with Tanner Linsley: React Query to TanStack Start | React Universe On Air #50

    Tanner Linsley joins React Universe On Air to unpack the evolution of the TanStack ecosystem—from React Table and React Query to TanStack Router and the newest addition to the family, TanStack Start ✨ What started as internal tooling for Nozzle became a suite of libraries that shaped how developers think about server state, routing, and full-stack React apps. In this episode, Tanner shares the technical decisions behind building framework-agnostic, headless tools—and explains why client-side architecture still matters in a server-first world. You’ll also hear why TanStack Start isn’t just another full-stack framework, how React Server Components could be treated like server state, and what’s coming next for TanStack Router. If you're building React apps at scale or deciding how to modernize your frontend stack, don’t skip this one!
