unit-jest plugin for vue-cli

Last verified Sep 9, 2026 against @vue/cli-plugin-unit-jest@5.0.9.

@vue/cli-plugin-unit-jest ships CommonJS only. require("@vue/cli-plugin-unit-jest") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. import "@vue/cli-plugin-unit-jest" 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("@vue/cli-plugin-unit-jest") 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 cliPluginUnitJest from "@vue/cli-plugin-unit-jest"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: no types are available for @vue/cli-plugin-unit-jest; declare the module yourself if you need them.
