   - `customHash` - Default: none - If set, overrides the md5 checksum calculation with the result of calling `customHash(buffer, pathToFile)`. If it is not a `function`, `customHash` is used as the hash value. If it is set to `null`, fingerprinting is skipped and only prepending occurs.
   - `generateAssetMap` - Default: false. If true, will generate a `assetMap.json` file in a `assets` directory on the output node. This file contains a mapping of the original asset name to the fingerprinted asset, like the following:
   - `assetMapPath` - Default: `'assets/assetMap-HASH.json'` - The path in the destination folder to store the `assetMap.json` in. Only for the default value, `HASH` will be replace with the fingerprint of the file.
