Last verified Sep 9, 2026 against @vue/cli-service@5.0.9.

@vue/cli-service ships CommonJS only. require("@vue/cli-service") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js ^12.0.0 || >= 14.0.0. import "@vue/cli-service" 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-service") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js ^12.0.0 || >= 14.0.0.
2. From ES modules use the default import: import cliService from "@vue/cli-service"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: types are bundled; install nothing extra.
