Node-API

Use Bun’s Node-API module to build native add-ons to Node.js

Node-API is an interface for building native add-ons to Node.js. Bun implements 95% of this interface from scratch, so most existing Node-API extensions work with Bun. See issue #158 for completion status.

As in Node.js, you can require() .node files (Node-API modules) directly.

const napi = require("./my-node-module.node");

Alternatively, use process.dlopen:

let mod = { exports: {} };
process.dlopen(mod, "./my-node-module.node");
