Summary

TypeScript NodeNext module resolution can’t resolve OpenTUI’s extensionless re-exports from its declaration files, which hides exported APIs like createCliRenderer and createRoot.

Details

• @opentui/core index.d.ts contains export * from "./renderer"
• @opentui/react src/index.d.ts contains export * from "./reconciler/renderer"

With TS 5.9 and moduleResolution: "NodeNext", tsc --traceResolution reports “Module name './renderer' was not resolved” even though renderer.d.ts exists. This results in TS2305 (“no exported member”).

Repro

// tsconfig.json
{
  "compilerOptions": {
    "module": "NodeNext",
    "moduleResolution": "NodeNext"
  }
}

import { createCliRenderer } from '@opentui/core'
import { createRoot } from '@opentui/react'

Workaround

Use moduleResolution: "Bundler" in the consumer tsconfig so TS accepts extensionless re-exports.

Request

Consider adding explicit extensions in declaration re-exports (e.g. ./renderer.js / ./reconciler/renderer.js) or adjusting the package exports so NodeNext resolution works without the Bundler override.
