eslint-friendly-formatter ships CommonJS only. require("eslint-friendly-formatter") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=0.10.0. import "eslint-friendly-formatter" 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("eslint-friendly-formatter") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=0.10.0.
2. From ES modules use the default import: import eslintFriendlyFormatter from "eslint-friendly-formatter"; then destructure. Named imports only work when Node.js can statically detect the exports.
