….js ESM Node.js ESM requires explicit file extensions for subpath imports. Without the .js extension, Node.js throws: Error: Cannot find module 'react-reconciler/constants' Did you mean to import "react-reconciler/constants.js"? This affects projects using @opentui/react with Node.js test runners like Vitest that run in ESM mode. Co-Authored-By: Claude Opus 4.5 <[email protected]>

Problem
Node.js ESM mode requires explicit file extensions for subpath imports from packages. The current code imports from
react-reconciler/constantswithout the.jsextension, which works in Bun but fails in Node.js:This breaks projects using
@opentui/reactwith Node.js-based test runners like Vitest running in ESM mode.Solution
Add the
.jsextension to the tworeact-reconciler/constantsimports:packages/react/src/reconciler/host-config.tspackages/react/src/reconciler/reconciler.tsThis is backward compatible - the
.jsextension works correctly in both Bun and Node.js.Testing
Tested with Vitest in a pnpm monorepo - the import errors are resolved.
