This module uses rollup to create a selectively minified build of lodash using npm scripts. This package was made in response to the deprecation of the official lodash-cli utility.

npm i -D rolldash

rolldash [-v --version <latest|'4.0.0'>] [-c --config <path|'./rolldash.config.js'>] -o --output <path>

1. Fetches a local copy of Lodash of the specified version
2. Reads the configuration file containing the regex/string names of valid Lodash exports
3. The build script dynamically generates a build script in memory and uses it to build a selectively exported version of Lodash locally to the specified output location.

rolldash -v 4.0.1 ./build/lodash.js

The above will fetch version 4.0.1 of Lodash, use rolldash.config.js in the current working directory, and output the file to ./build/lodash.js relative to the current working directory.

The configuration file used by the build tool is specified by a simple module export of an object containing use with allows for both strings and regular expressions.

module.exports = {
	compressor: {
		// uglifyJS2 settings
	},
	use: [
		'map',
		/difference/,
	],
};

The above will match any Lodash exports exactly named map, and any exports containing the word difference. The build script will output the detected exports when run.
