Dual (CommonJS + ESM) Dual package — require() works on every Node.js version we test; import works too

@vue/test-utils publishes both a CommonJS entry and a native ESM entry (ESM added in 1.3.1). require("@vue/test-utils") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. import "@vue/test-utils" works alongside it.

What to do

  1. Nothing to change. require("@vue/test-utils") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. import * as testUtils from "@vue/test-utils" works alongside it; use named imports for what the ESM entry exports.
  2. TypeScript: types are bundled; install nothing extra.
