Password protected SPARQL endpoints

[semanticfire]

how should I configure a password protected endpoint?

[yuricus]

To access password-protected endpoint, you should pass your own queryFunction in constructor of SparqlDataProvider, see default implementation in sparqlDataProvider.ts - queryInternal(), you will need to pass authentication header along with the HTTP request.

const queryFunction: QueryFunction = …
new SparqlDataProvider(options: { queryFunction }}
