Flow Type Stripper

A command-line tool that processes JavaScript files and removes Flow type annotations, converting Flow-typed code to standard JavaScript.

Capabilities

Directory Processing with Extension Filtering

The tool should:

• Process only files with specified extensions (e.g., .js, .jsx) @test
• Handle multiple file extensions in a single operation @test
• Skip files that don't match the extension filter @test

Requirements

Build a tool that processes all files in a directory, removing Flow type annotations. The tool must filter files by extension before processing.

Extension filtering requirements:

• Accept a comma-separated list of extensions (e.g., .js,.jsx,.mjs)
• Only process files matching the specified extensions
• Process directories recursively
• Default extensions when none specified: .js,.mjs,.cjs,.jsx,.flow,.es6
