https://github.com/thernstig/eslint-mcp-jiti

To Reproduce

1. Install the packages
2. Execute this in a terminal: node -e "import {configs} from '@next/eslint-plugin-next';"

Current vs. Expected behavior

Expected

It should return with no errors.

Actual

> node -e "import {configs} from '@next/eslint-plugin-next';"
file:///home/tobias/code/repro-eslint-mcp-jiti/[eval1]:1
import {configs} from '@next/eslint-plugin-next';
        ^^^^^^^
SyntaxError: Named export 'configs' not found. The requested module '@next/eslint-plugin-next' is a CommonJS module, which may not support all module.exports as named exports.
CommonJS modules can always be imported via the default export, for example using:

import pkg from '@next/eslint-plugin-next';
const {configs} = pkg;

Additional context

I do not know what the fault is, but I compared how @next/eslint-plugin-next sets its named exports compared to typescript-eslint, which also sets named exports (both being in Common JS (CJS)). An AI summarized it as below. Again, might be wrong, but adding for context:

@next/eslint-plugin-next defines top-level getters on exports
Object.defineProperty(exports, "configs", { enumerable: true, get: () => configs });
Node ignores top-level getters for synthetic named exports when importing CJS as ESM.

typescript-eslint works because it assigns a data property at the top level:
exports.configs = createConfigsGetters({ ... }); // data property
Node sees a top-level data property → creates a synthetic named export → import { configs } works.

To fix @next/eslint-plugin-next do this:

// Instead of top-level getter:
Object.defineProperty(exports, "configs", {
 enumerable: true,
 value: configs  // <- data property, not a getter
});
