Shareable commitlint config enforcing conventional commits

Last verified Sep 9, 2026 against @commitlint/config-conventional@21.2.2. JSON

ESM-only ESM-only since 19.0.0 — last CommonJS version is 18.6.3

@commitlint/config-conventional dropped its CommonJS build in 19.0.0 (February 2024). The last version you can require() on every Node.js version, including 18 and older, is 18.6.3, published Mar 11, 2024.

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

@commitlint/config-conventional@21.2.2 declares engines ">=22.12.0", so Node.js 18, 20 are outside its supported range regardless of module format.
