})();

Interface

function file(filePath: string, options?: Options): Promise<Result>;

interface Options {
	fileBinPath?: string; // path to file binary to be used instead of default
	mimeType?: boolean; // if set to true, result will contain detected mime-type of file. Default false.
	separator?: string; // default ':'
	alternativeSeparators?: string[]; // default [';', '$', '€', '>', '<']
}

interface Result {
	mimeType?: string; // detected mime-type of file (if option mimeType set to true)
	charset?: string; // detect charset of file (if option mimeType set to true)
	types?: string[]; // get all detected general types (if no mimeType set)
}

Get version of file

import { getVersion } from '@signageos/file';

(async function () {
	const version = await getVersion();
	console.log(version); // file-5.32
})();
