Last verified Sep 9, 2026 against react-intl@10.1.26.

react-intl dropped its CommonJS build in 8.0.0 (December 2025). The last version with a plain require()-able CommonJS entry is 7.1.14, published Oct 9, 2025.

On Node.js 20.19+, 22.12+ and newer, require("react-intl") 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("react-intl") fails with ERR_REQUIRE_ESM.

## What to do

1. On Node.js 20.19+, 22.12+ and newer, require("react-intl") 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 reactIntl = await import("react-intl"). That works on every Node.js version the package supports.
3. If you need a synchronous require() or run Node.js 18: npm install react-intl@7.1.14, the last CommonJS release (published Oct 9, 2025).
4. TypeScript: types are bundled; install nothing extra.
