Typescript: Type 'NamedNode' is missing the following properties from type 'NamedNode': classOrder, dir, site, doc, and 9 more

[eroux]

When doing the following:

import * as rdf from 'rdflib'
const exfoo :rdf.NamedNode = rdf.Namespace("http://example.com/")("foo")

I'm getting:

Type 'NamedNode' is missing the following properties from type 'NamedNode': classOrder, dir, site, doc, and 9 more.  TS2740

  > 22 | const exfoo :rdf.NamedNode = rdf.Namespace("http://example.com/")("foo")
       |       ^
    23 | 

which is a bit bizarre... I believe this comes from the multiple declarations of NamedNode, once as an interface here and once as a class here.

The interface is the returned type of rdf.Namespace("http://example.com/")("foo") as seen here, while the class is what gets exported by the rdflib module here.

Effectively there seems to be no valid type for exfoo that I could use, as the NamedNode interface is not exported.

Is it possible to export the interfaces, or implement any another appropriate solution?

I'm having the same issue and found here. Can't believe it's an old issue of 4 years without any response (at least clarification)...

(Note that in the current version of rdflib, you can do import { NamedNode } from 'rdflib/lib/tf-types'; to resolve the original issue.)

I understand the reason for having a separete NamedNode interface, which is to be compatible with the rdf.js specification. However, the defined NamedNode interface is not compatible with that from @rdfjs/types, the reference type definition. In particular, it misses the ? aspect of the equals() method.

I'm not sure if this is a version issue, as I'm not experienced enough with rdfjs either. But this inconsistency should be resolved to remain compatible.
