This does not support streaming unless you enable the supportsAnyType option.

onFile

The async function called for each Vinyl file in the stream. Must return a modified or new Vinyl file.

options

supportsDirectories

Whether the plugin can handle directories.

supportsAnyType

You can yield more files from it if needed.

		async file => { … },
		{
			async * onFinish() {
				yield someVinylFile;

			}
		}
	);
