# Is node-notifier ESM-only? Can you require() it?

> node-notifier@10.0.1 is a CommonJS package. CommonJS — require() works on every Node.js version we test.

A Node.js module for sending notifications on native Mac, Windows (post and pre 8) and Linux (or Growl as fallback)

Last verified Sep 9, 2026 against node-notifier@10.0.1.

node-notifier ships CommonJS only. require("node-notifier") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. import "node-notifier" 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("node-notifier") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun.
2. From ES modules use the default import: import nodeNotifier from "node-notifier"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: npm install -D @types/node-notifier
