index.cts

import { globToTree } from './index';

export = globToTree

index.ts

export function globToTree(): any {}
Object.defineProperty(globToTree, "__esModule", { value: true });
Object.defineProperty(globToTree, "globToTree", { value: globToTree });
Object.defineProperty(globToTree, "default", { value: globToTree });
export default globToTree

🙁 Actual behavior

show error

or use @ts-ignore avoid it

import { globToTree } from './index';

// @ts-ignore
export = globToTree

🙂 Expected behavior

no need @ts-ignore

What code is supposed to be generated in this case?

https://github.com/bluelovers/ws-glob/blob/master/packages/glob-tree-list/dist/index.esm.mjs - this is just a default export, like it's telling you to do. export = (a function doesn't make sense in an ES Module output format. What's the motivation for not writing export default globToTree ?

Ryan Cavanaugh (@RyanCavanaugh) I guess they’re expecting the .cts file to compile to CommonJS instead of ESM?
