Last verified Sep 9, 2026 against karma-mocha-reporter@2.2.5.

karma-mocha-reporter ships CommonJS only. require("karma-mocha-reporter") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. import "karma-mocha-reporter" 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("karma-mocha-reporter") 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 karmaMochaReporter from "karma-mocha-reporter"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: npm install -D @types/karma-mocha-reporter
