re-Script

JavaScript unminifier and deobfuscator powered by AI.

re-Script transforms minified and obfuscated JavaScript into readable code using AI models like Claude, GPT-4, or local LLMs. It combines traditional tools like webcrack and Babel with intelligent variable renaming.

Features

• Multi-LLM support (OpenAI, Anthropic, Ollama, Azure, Bedrock)
• Batch processing for multiple files or directories
• AST-aware code splitting
• Response caching to reduce API costs
• Error recovery when processing steps fail
• File-based configuration with CLI overrides
• Real-time progress tracking
• Dry run mode
• Watch mode for automatic processing

npm install -g @roeintheglasses/re-script

Usage

Quick Start

# Interactive setup (recommended for first time)
re-script init

# Process a single file
re-script app.min.js

# Process directory recursively
re-script src/ --recursive --output dist/

Configuration

Create config with interactive setup:

re-script init

Or manage config manually:

# Show current config
re-script config show

# Set values
re-script config set provider.name anthropic
re-script config set provider.apiKey "your-key"

# Validate config
re-script config validate

Examples

# Single file
re-script bundle.min.js

# Multiple files
re-script file1.min.js file2.min.js

# Directory with pattern
re-script src/ --pattern "*.min.js" --recursive

# Dry run to preview changes
re-script app.min.js --dry-run

# Custom output location
re-script app.min.js --output app.readable.js

# Exclude patterns
re-script src/ --recursive --exclude "node_modules/**" "*.test.js"

# High concurrency
re-script src/ --recursive --concurrency 10

Providers

# OpenAI
re-script app.min.js --provider openai --model gpt-4o

# Anthropic  
re-script app.min.js --provider anthropic --model claude-3-5-sonnet-20241022

# Local Ollama
re-script app.min.js --provider ollama --model codellama:13b

# Azure OpenAI
re-script app.min.js --provider azure --model gpt-4o

Configuration

Config Files

re-Script looks for:

• .rescriptrc.json
• .rescriptrc.yaml
• rescript.config.js
• package.json (in rescript field)

Environment Variables

export ANTHROPIC_API_KEY=your-key-here
export OPENAI_API_KEY=your-key-here
export OLLAMA_BASE_URL=http://localhost:11434
export RESCRIPT_DEBUG=true

Config Commands

# Show current config
re-script config show

# Show with environment variables
re-script config show --env

# Set values
re-script config set provider.name openai
re-script config set provider.model gpt-4o

# Get values
re-script config get provider.name

# List all available keys
re-script config list

# Validate configuration
re-script config validate

Additional Commands

# Show usage examples
re-script examples

# Interactive setup wizard
re-script init

# Help and version
re-script --help
re-script --version

How It Works

re-Script processes files through a 4-step pipeline:

1. Webcrack Processing - Reverse bundling and deobfuscation
2. Babel Transformations - AST-based code improvements
3. LLM Processing - AI-powered variable/function renaming
4. Code Formatting - Final prettification

Each step can fail gracefully without breaking the pipeline. Responses are cached to reduce API costs.

Troubleshooting

Common Issues

API Key Errors

re-script config set provider.apiKey your-key-here
