string-argv is a lightweight npm package designed for parsing command-line argument strings into an array of arguments, similar to how process.argv works but from a string input. It handles complex scenarios like quoted arguments, escaped characters, and whitespace separation. This utility is particularly useful for testing command-line interfaces, processing user input in CLIs, or simulating command-line execution within applications. string-argv offers a simple and reliable way to decompose command-line strings into manageable argument lists.
