@comunica/actor-http-fetch

Comunica Fetch HTTP Actor

An HTTP actor that uses cross-fetch to perform HTTP requests.

This module is part of the Comunica framework, and should only be used by developers that want to build their own query engine.

When this actor is used, a custom fetch implementation may be provided via the context (fetch). If none is provided, the default fallback fetch implementation will be used (node-fetch in Node.js, and the browser's fetch in browser environments).
