Last verified Sep 9, 2026 against vue-tsc@3.3.11.

vue-tsc ships CommonJS only. require("vue-tsc") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. import "vue-tsc" 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-tsc") 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 vueTsc from "vue-tsc"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: types are bundled; install nothing extra.
