The last version you can require() on every Node.js version, including 18 and older, is 3.0.7, published Jun 14, 2026. On Node.js 20.19+, 22.12+ and every newer release, require(\"http-proxy-middleware\") works anyway: Node can load synchronous ES modules through require(). Verified on Node 22, 24, 26. Node.js 18 and older still fail with ERR_REQUIRE_ESM. http-proxy-middleware@4.2.0 declares engines \"^22.15.0 || ^24.0.0 || >=26.0.0\", so Node.js 18, 20 are outside its supported range regardless of
