## README

# Comunica File Dereference Actor

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

A comunica File Dereference Actor.

An [Dereference](https://github.com/comunica/comunica/tree/master/packages/bus-dereference) actor that
resolves an URL to a local file (optionally starting with `file://`).

This actor refuses to dereference files if the `@comunica/bus-dereference:blockFileAccess` context entry is enabled.
This is for example set for SERVICE targets,
so that queries from untrusted parties can not read arbitrary local files.
