Last verified Sep 9, 2026 against @semantic-release/commit-analyzer@13.0.1.

@semantic-release/commit-analyzer dropped its CommonJS build in 10.0.0 (June 2023). The last version with a plain require()-able CommonJS entry is 9.0.2, published Nov 23, 2021; it declares support for Node.js >=14.17.

On Node.js 20.19+, 22.12+ and newer, require("@semantic-release/commit-analyzer") works with the latest version: Node.js loads synchronous ES modules through require(). Verified on Node.js 20, 22, 24 and 26. Node.js 18 has no require(esm), and @semantic-release/commit-analyzer@13.0.1 declares Node.js >=20.8.1, so 18 is outside its supported range anyway.

@semantic-release/commit-analyzer@13.0.1 declares engines ">=20.8.1", so Node.js 18 is outside its supported range regardless of module format.

## What to do

1. On Node.js 20.19+, 22.12+ and newer, require("@semantic-release/commit-analyzer") 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 commitAnalyzer = await import("@semantic-release/commit-analyzer"). That works on every Node.js version the package supports (>=20.8.1).
3. If you need a synchronous require() or run Node.js 18: npm install @semantic-release/commit-analyzer@9.0.2, the last CommonJS release (published Nov 23, 2021); it declares Node.js >=14.17.
4. @semantic-release/commit-analyzer@13.0.1 declares engines ">=20.8.1", so Node.js 18 is unsupported regardless: upgrade Node.js or pin an older release.
5. TypeScript: no types are available for @semantic-release/commit-analyzer; declare the module yourself if you need them.
