ESM-only ESM-only since 10.0.0 — last CommonJS version is 9.1.20

@storybook/addon-docs dropped its CommonJS build in 10.0.0 (October 2025). The last version with a plain require()-able CommonJS entry is 9.1.20, published Mar 5, 2026.

require("@storybook/addon-docs") failed in our probe on Node.js 20+ as well; see the runtime table for the error before relying on it. On Node.js 18, which has no require(esm), require("@storybook/addon-docs") fails with ERR_REQUIRE_ESM.

What to do

  1. require("@storybook/addon-docs") failed in our probe on Node.js 20+ as well; see the runtime table for the error before relying on it.
  2. From a CommonJS file, use a dynamic import inside an async function: const addonDocs = await import("@storybook/addon-docs"). That works on every Node.js version the package supports.
  3. If you need a synchronous require() or run Node.js 18: npm install @storybook/addon-docs@9.1.20, the last CommonJS release (published Mar 5, 2026).
  4. TypeScript: types are bundled; install nothing extra.
