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

Monorepo Architecture with Nx
Should you be afraid of monorepos? Not with Nx. Tune in and learn how to scale apps without scaling pain.
In this episode of React Universe On Air, Łukasz Chludziński chats with Jordan Powell from Nx to explore what it really takes to build and manage a monorepo at scale. From dependency graphs to distributed CI tasks, they break down how Nx helps teams stay fast, focused, and frustration-free. Whether you're just getting started with Yarn Workspaces or running into CI bottlenecks, this episode gives you the strategies and context to go further with less overhead.
Key learnings
➡️ The difference between monorepos and monoliths
➡️ How Nx graphs improve selective builds and testing
➡️ What “ownership rules” mean for large codebases
➡️ How distributed task execution saves time in CI
➡️ Why better DX equals better business outcomes
➡️ Real-world patterns for React Native and full-stack monorepos
