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

``bash
npm install -g @roeintheglasses/re-script
`

Usage

$3

`bash


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/
`

$3

Create config with interactive setup:

`bash
re-script init
`

Or manage config manually:

`bash


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

`bash


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
`

$3

`bash


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

$3

re-Script looks for:
- .rescriptrc.json
- .rescriptrc.yaml
- rescript.config.js
- package.json (in rescript field)

$3

`bash
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
`

$3

`bash


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

`bash

Interactive setup wizard

Help and 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.
