JSDoc linting rules for ESLint.

Last verified Sep 9, 2026 against eslint-plugin-jsdoc@64.3.8.

eslint-plugin-jsdoc dropped its CommonJS build in 64.0.0 (August 2026). The last version with a plain require()-able CommonJS entry is 63.3.3, published Aug 2, 2026; it declares support for Node.js ^22.13.0 || >=24.

On Node.js 22.12+ and newer (eslint-plugin-jsdoc@64.3.8 declares Node.js ^22.22.2 || >=24.15.0), require("eslint-plugin-jsdoc") works with the latest version: Node.js loads synchronous ES modules through require(). Verified on Node.js 22, 24 and 26. Node.js 18 has no require(esm), and eslint-plugin-jsdoc@64.3.8 declares Node.js ^22.22.2 || >=24.15.0, so 18 is outside its supported range anyway.

eslint-plugin-jsdoc@64.3.8 declares engines "^22.22.2 || >=24.15.0", so Node.js 18, 20 are outside its supported range regardless of module format.

## What to do

1. On Node.js 22.12+ and newer (eslint-plugin-jsdoc@64.3.8 declares Node.js ^22.22.2 || >=24.15.0), require("eslint-plugin-jsdoc") works with the latest version: Node.js loads synchronous ES modules through require(). Verified on Node.js 22, 24 and 26.
2. From a CommonJS file, use a dynamic import inside an async function: const eslintPluginJsdoc = await import("eslint-plugin-jsdoc"). That works on every Node.js version the package supports (^22.22.2 || >=24.15.0).
3. If you need a synchronous require(): npm install eslint-plugin-jsdoc@63.3.3, the last CommonJS release (published Aug 2, 2026); it declares Node.js ^22.13.0 || >=24.
4. eslint-plugin-jsdoc@64.3.8 declares engines "^22.22.2 || >=24.15.0", so Node.js 18, 20 are unsupported regardless: upgrade Node.js or pin an older release.
5. TypeScript: types are bundled; install nothing extra.
