Explore how Microsoft engineers Vladimir Morozov and Khalef Hosany demonstrate the powerful integration of Hermes with Node API in this 25-minute conference talk from React Universe Conf 2025. Learn about Node API as the industry standard for building native add-ons in Node.js, understanding its engine-agnostic and ABI-stable characteristics that make it versatile for runtimes like Deno, Bun, and React Native. Discover how React Native Windows adopted Node API to support multiple engines and programming languages, and examine a fork of Hermes that reimplements JSI on top of Node API along with the roadmap for upstreaming this work. Watch live demonstrations showing Node API modules compiled once and running seamlessly across different environments, including Hermes. Understand what this integration unlocks for developers: universal native modules, cross-runtime portability, and the ability to use the latest Hermes with older React Native versions. Gain insights into how the combination of Hermes and Node API creates a more stable, extensible, and future-proof foundation for React Native development, with practical implications for building more compatible and maintainable native modules.
