TS4058: Return type of exported function has or is using name WebSiteLeaf from external module ... but cannot be named

[btakita]

When declaring an object to be a WebSite type, a TS4058 appears.

export function jsonld_WebSite_() { // TS4058
	return <WebSite>{
		'@type': 'WebSite',
		'@id': jsonld_WebSite_id,
		url: website,
		name: title,
		mainEntity: jsonld_Person_(),
	}
}

Looking at the source,

export type WebSite = WebSiteLeaf;

WebSiteLeaf is not in use anywhere else nor is it exported. It seems that WebSiteLeaf should be renamed to WebSite. The intermediate type is not necessary.

Another solution is to add exports for all of the Leaf & Base types.

See microsoft/TypeScript#9944 & microsoft/TypeScript#9944

When I manually add an export to WebSiteLeaf, the error goes away:

export interface WebSiteLeaf extends WebSiteBase {
    "@type": "WebSite";
}

I published the @btakita/schema-dts package with #194. I will use this we can find a resolution for this issue.

I was able to resolve the issue by setting composite: false in my tsconfig.json file.

See microsoft/TypeScript#42873 (comment)

Closing since my issue if fixed.
