Is prettier-eslint ESM-only? Can you require() it?

Formats your JavaScript using prettier followed by eslint --fix

Last verified Sep 9, 2026 against prettier-eslint@17.1.2. JSON

ESM-only ESM-only since 17.1.0 — last CommonJS version is 17.0.1

prettier-eslint dropped its CommonJS build in 17.1.0 (June 2026). The last version you can require() on every Node.js version, including 18 and older, is 17.0.1, published Jun 14, 2026.

On Node.js 20.19+, 22.12+ and every newer release, require("prettier-eslint") works anyway: Node can load synchronous ES modules through require(). Verified on Node 20, 22, 24, 26. Node.js 18 and older still fail with ERR_REQUIRE_ESM.

prettier-eslint@17.1.2 declares engines "^20.19.0 || ^22.13.0 || >=24", so Node.js 18 is outside its supported range regardless of module format.
