stripper-cli

A simple CLI tool that copies directories and removes comments from JavaScript and TypeScript files.

This is my first npm package! Built it because I needed a quick way to clean up code comments for build processes :).

Features

• Removes // and /* */ comments from JS/TS files
• Supports glob patterns for excluding files (*.test.js, lib/, etc.)
• Safe operation with marker files (won't overwrite existing directories)
• Shows processing statistics

Installation

# Install globally
npm install -g stripper-cli

# Or use directly without installing
npx stripper-cli -s ./src -d ./dist

Usage

stripper-cli -s <source> -d <destination> [options]

Options

| Option | Aliases | Description | |--------|---------|-------------| | -s <path> | --source | Source directory | | -d <path> | --destination | Destination directory | | --exclude <pattern> | | Exclude files/folders (supports glob patterns) | | --no-minified | | Skip .min.js files | | --verbose | -v | Show detailed output | | --help | -h | Show help |

Examples

# Basic usage
stripper-cli -s ./src -d ./dist

# Exclude specific folders
stripper-cli -s ./src -d ./dist --exclude "lib/" --exclude "*.test.js"

# Skip minified files and show verbose output
stripper-cli -s ./src -d ./dist --no-minified --verbose

What it does

Before:

function test() {
    console.log('Hello'); // This prints hello
    /* Multi-line
       comment here */
    return 42;
}

After:

function test() {
    console.log('Hello'); 
    
    return 42;
}

Common patterns

# Exclude libraries and tests
stripper-cli -s ./src -d ./dist --exclude "lib/" --exclude "*.test.js"

# Skip all minified files
stripper-cli -s ./src -d ./dist --no-minified

# See what's happening
stripper-cli -s ./src -d ./dist --verbose

Safety

The tool creates a .stripper-cli-marker file in the destination. If the destination exists without this marker, it will abort to prevent data loss.
