Ever hit a wall trying to integrate native libraries in React Native that aren’t written in C or C++? Robert Pasinski, Senior Software Engineer at Callstack, shares how to break past those limitations, without writing a single TurboModule.

Presented at the React Universe Meetup in Wrocław (April 2024), this talk introduces PolyGen, a new toolkit that uses WebAssembly to embed code written in languages like Rust, Go, and even COBOL into your React Native apps. Robert dives into performance trade-offs, platform compatibility, build system headaches, and how WebAssembly provides a unified ABI that makes it all… just work.

Facing complex cross-platform challenges?

We help deliver consistent experiences across platforms with one codebase.
