I've been contributing a Conformance Test Suite to the Node.js project: For Node-API implementors to run across different JavaScript engines and runtimes, such as Bun, Deno and React Native.
I want to share motivation for the project, architectural decisions, the progress we've made so far and key techniques used to ensure the implementation stays runtime agnostic.
This talk has been presented at Node Congress 2026, check out the latest edition of this JavaScript Conference.
