Example usage

const FileManager = require("@e-mc/file-manager");

FileManager.loadSettings({ // Global
    process: {
        thread: { sub_limit: 16 }
    },
    request: {
        timeout: "15s",
        disk: {
            enabled: true,
            limit: "1gb", // Content-Length
            expires: "1d",
            exclude: ["https://github.com", "zip"]
        },
        buffer: {
            enabled: true,
            limit: "64mb",
            limit_all: "512mb",
            expires: "1h",
            purge_amount: 0.25 // When limit_all exceeded
        }
    },
    permission: {
        disk_read: ["**/*"],
        disk_write: ["/tmp/**"]
    }
});

const requestData = {
  assets: [
    { uri: "http://hostname/path/document1.png" }, // /path/workspace/document1.png
    { pathname: "output", uri: "http://hostname/path/unknown", mimeType: "image/png" }, // /path/workspace/output/unknown.png
    { pathname: "output", filename: "image2.png", uri: "http://hostname/path/document2.png" } // /path/workspace/output/image2.png
  ],
  incremental: "etag",
  threads: 8,
  log: {
    showSize: true,
    showProgress: true,
    showDiff: [
      "**/assets/*.js", // Local path
      "javascript", // application/javascript | text/javascript
      "text/css"
    ]
  }
};

const instance = new FileManager("/path/workspace", requestData, { disk_write: ["/path/workspace/output/**"] });
await instance.start();

NOTE: FileManager is a sub-class of Host and Module. Their loadSettings will be called as well which uses a combined Settings object.
