Request configuration

requestConfig controls how queries are sent to the endpoint. It is accepted by both SparqlEditor and SparqlStudio (where it sets the default for every tab).

Every field may be a value or a (sparqlEditor) => value function, so you can compute it per request.

new SparqlStudio(el, {
  requestConfig: {
    endpoint: "https://sparql.dblp.org/sparql",
    method: "POST",
    headers: () => ({ Authorization: `Bearer ${getToken()}` }),
    withCredentials: false,
  },
});

field	default	description
endpoint	—	SPARQL endpoint URL
method	"POST"	"GET" or "POST"
acceptHeaderSelect	application/sparql-results+json,*/*;q=0.9	accept header for SELECT / ASK
acceptHeaderGraph	application/n-triples,*/*;q=0.9	accept header for CONSTRUCT / DESCRIBE
acceptHeaderUpdate	text/plain,*/*;q=0.9	accept header for updates
namedGraphs / defaultGraphs	[]	graph URIs
args	[]	extra { name, value } request args
headers	{}	extra HTTP headers
withCredentials	false	send credentials (cookies) with the request
adjustQueryBeforeRequest	false	(sparqlEditor) => string to rewrite the query before sending

CORS

If the endpoint does not return CORS headers, set a corsProxy on SparqlStudio rather than fighting the request config. See SparqlStudio · CORS.
