Last verified Sep 9, 2026 against @vueuse/core@14.4.0.

@vueuse/core dropped its CommonJS build in 13.0.0 (March 2025). The last version with a plain require()-able CommonJS entry is 12.8.2, published Mar 5, 2025.

On Node.js 20.19+, 22.12+ and newer, require("@vueuse/core") works with the latest version: Node.js loads synchronous ES modules through require(). Verified on Node.js 20, 22, 24 and 26. On Node.js 18, which has no require(esm), require("@vueuse/core") fails with ERR_REQUIRE_ESM.

## What to do

1. On Node.js 20.19+, 22.12+ and newer, require("@vueuse/core") works with the latest version: Node.js loads synchronous ES modules through require(). Verified on Node.js 20, 22, 24 and 26.
2. From a CommonJS file, use a dynamic import inside an async function: const core = await import("@vueuse/core"). That works on every Node.js version the package supports.
3. If you need a synchronous require() or run Node.js 18: npm install @vueuse/core@12.8.2, the last CommonJS release (published Mar 5, 2025).
4. TypeScript: types are bundled; install nothing extra.
