# Comunica Fetch HTTP Actor

[![npm version](https://badge.fury.io/js/%40comunica%2Factor-http-fetch.svg)](https://www.npmjs.com/package/@comunica/actor-http-fetch)

An [HTTP](https://github.com/comunica/comunica/tree/master/packages/bus-http) actor that
uses [fetch](https://fetch.spec.whatwg.org/) to perform HTTP requests.

When this actor is used in Node.js, a memory-based cache will be initialized.
This cache is only used when the `httpCache` context flag is enabled.

This module is part of the [Comunica framework](https://github.com/comunica/comunica),
and should only be used by [developers that want to build their own query engine](https://comunica.dev/docs/modify/).

When this actor is used, a custom fetch implementation may be provided via the context (`fetch`).
If none is provided, the global `fetch` implementation from the runtime or a polyfill is used.
