    Building v0 iOS and Fixing React Native Along the Way With Fernando Rojo, Szymon Rybczak & Oskar Kwaśniewski

    Vercel’s v0 iOS app is built with React Native, but it looks and feels like a fully native iOS product. In this episode of React Universe On Air, we go deep into how the v0 mobile app was built: from choosing Expo and going iOS-first, to writing native modules, fixing low-level React Native issues, and upstreaming improvements back to the ecosystem. This is a hands-on engineering conversation with Fernando Rojo, Szymon Rybczak, and Oskar kwaśniewski about real trade-offs, real constraints, and what it takes to ship a polished app under real deadlines.

    A (Secure) Christmas Carol: The Story of Npmezer Scrooge | Coffee Talk

    This year, React Universe On Air is doing something different for Christmas. No guests, demos, or framework updates. Instead, Ola Desmurs Linczewska tells a Christmas story. A (Secure) Christmas Carol is a holiday fairytale for JavaScript and React Native developers. Set on Christmas Eve, it follows Npmezer Scrooge, a senior engineer who believes deadlines matter more than holidays, and warnings can always wait. Over the course of one long winter night, he’s visited by unexpected guides who show him what his choices look like across time: the optimism of the past, the quiet damage of the present, and a future no one wants. All technical details, real-world security issues, and references mentioned in the story are explained in the show notes 📚  https://clstk.com/4pEVYwv We’ll be back in January with regular episodes. Until then, stay kind, stay curious, and have yourself a very merry Christmas.

  6. Observability & OpenTelemetry in React Native

    13.08.2025

    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?
