Node-API introduces a stable interface for writing native modules in React Native using languages like C++, Rust, and Swift. By abstracting away runtime internals, it lets you build modules that work across JavaScript engines and environments without rewriting or refactoring native code for each one. This allows you to distribute precompiled binaries, integrate existing native libraries, and share modules across ecosystems such as Node.js, Deno, and Bun.

In this live session on July 15 at 5PM CEST, Kræn Hansen, Mariusz Pasiński, and Łukasz Chludziński will walk through how Node-API works within React Native, how it improves build speed and maintainability, and how to architect native modules that perform well across platforms. You’ll see real-world examples of using Node-API to interface with system APIs, embed high-performance routines, and unify cross-runtime tooling.
