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?…

Eighteen TV platforms, one codebase—what could possibly go wrong? Tune in to find out how to tackle the technical and UX challenges of building for Android TV, Apple TV, Fire TV, Tizen, and more—all with React Native! In the 49th episode of React Universe On Air, Łukasz Chludziński (https://x.com/lukasz_app) teams up with Michael Khirallah (https://x.com/mkralla11), Senior Director of Engineering at DIRECTV, and Chris Trag (https://x.com/chris_trag), Developer Evangelist at Amazon, to discuss why cross-platform development is not just a time-saver but also a way to deliver a consistent user experience. You know that at Callstack, we’re all about performance—and with devices like Samsung’s Tizen TVs released in 2017 (running Chromium 47!), performance is a serious concern. That’s why we asked our guests to share real-world techniques for optimizing TV apps, from architectural choices to strategies that avoid unnecessary performance hits on newer devices. The complexity of TV app development doesn’t stop at coding, though. Our host and guests know it all to well, so they couldn’t help but discuss how they balance unit, integration, automation, and manual testing, leveraging tools like AWS Device Farm and custom-built frameworks to ensure stability across all supported platforms. What’s in it for you? Tips on automating QA without compromising thoroughness and why manual testing remains crucial for end-user experience. Want to get started with React Native TV app development?
