Is tsdx ESM-only? Can you require() it?

Zero-config TypeScript package development

Last verified Sep 9, 2026 against tsdx@2.0.0. JSON

ESM-only ESM-only since 2.0.0 — last CommonJS version is 0.14.1

tsdx dropped its CommonJS build in 2.0.0 (December 2025). The last version you can require() on every Node.js version, including 18 and older, is 0.14.1, published Oct 13, 2020.

require("tsdx") failed in our probe on Node.js 20+ as well. See the runtime matrix below for the exact error.

tsdx@2.0.0 declares engines ">=20", so Node.js 18 is outside its supported range regardless of module format.
