[BUG] - [MODULE_TYPELESS_PACKAGE_JSON] Warning: Module type of file://next-app-template/hero.ts?id=1771297031716 is not specified and it doesn't parse as CommonJS

[Key5n]

HeroUI Version

2.8.9

Describe the bug

Rather a work around than a bug report.
I definitely followed the official documentation to set up Hero UI, but I got the following warning after set up Hero UI with Next.js v16 and tailwindcss v4.

(node:17170) [MODULE_TYPELESS_PACKAGE_JSON] Warning: Module type of file:///Users/key5n/dev/heroui-nextjs-app/hero.ts?id=1771298920789 is not specified and it doesn't parse as CommonJS.
Reparsing as ES module because module syntax was detected. This incurs a performance overhead.
To eliminate this warning, add "type": "module" to /Users/key5n/dev/heroui-nextjs-app/package.json.
(Use `node --trace-warnings ...` to show where the warning was created)

You can eliminate this message with

1. "type": "module" in `package.json" as the message tells
2. renaming hero.ts to hero.mts

I prefer hero.mts rather attaching "type": "module".

This warning shows even on a template created with npx heroui-cli init.
I hope this warning would be resolved.
