Native Access to MacOS FSEvents

Last verified Sep 9, 2026 against fsevents@2.3.3.

fsevents ships CommonJS only. require("fsevents") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js ^8.16.0 || ^10.6.0 || >=11.0.0. import "fsevents" also works because Node.js and Bun can import CommonJS from ES modules, but only the default export is guaranteed; named imports depend on Node's static analysis of the module.

## What to do

1. require("fsevents") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js ^8.16.0 || ^10.6.0 || >=11.0.0.
2. From ES modules use the default import: import fsevents from "fsevents"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: types are bundled; install nothing extra.
