Last verified Sep 9, 2026 against typedoc-plugin-markdown@4.13.0.

typedoc-plugin-markdown dropped its CommonJS build in 4.3.0 (November 2024). The last version with a plain require()-able CommonJS entry is 4.2.10, published Nov 1, 2024; it declares support for Node.js >= 18.

On Node.js 20.19+, 22.12+ and newer, require("typedoc-plugin-markdown") works with the latest version: Node.js loads synchronous ES modules through require(). Verified on Node.js 20, 22, 24 and 26. On Node.js 18, which has no require(esm), require("typedoc-plugin-markdown") fails with ERR_REQUIRE_ESM.

## What to do

1. On Node.js 20.19+, 22.12+ and newer, require("typedoc-plugin-markdown") 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 typedocPluginMarkdown = await import("typedoc-plugin-markdown"). That works on every Node.js version the package supports (>= 18).
3. If you need a synchronous require() or run Node.js 18: npm install typedoc-plugin-markdown@4.2.10, the last CommonJS release (published Nov 1, 2024); it declares Node.js >= 18.
4. TypeScript: no types are available for typedoc-plugin-markdown; declare the module yourself if you need them.
