amdex

A command-line tool to extract and restore AMD-style JavaScript modules from bundled files.

Installation

npm install -g amdex
# or
pnpm add -g amdex
# or
yarn global add amdex

Usage

Restore AMD Modules

Extract and restore individual AMD modules from a bundled file:

amdex restore -i bundle.js -o ./output

Options:

• -i, --input <path>: Input bundle file path (required)
• -o, --output <path>: Output directory for extracted modules (default: "./restored")
• --include <pattern>: Include only modules matching this pattern (regex)
• --exclude <pattern>: Exclude modules matching this pattern (regex)

List Modules

List all AMD modules found in a bundle:

amdex list -i bundle.js

Options:

• -i, --input <path>: Input bundle file path (required)

Example

Given a bundled file with AMD modules:

define('module/a', ['jquery', 'underscore'], function($, _) {
    // module code
});

define('module/b', ['module/a'], function(moduleA) {
    // module code
});

Running:

amdex restore -i bundle.js -o ./src --include "module/.*"

Will create:

src/
  module/
    a.js
    b.js

Each file will contain its original AMD module definition with dependencies and implementation code.

Features

• Extracts AMD modules while preserving:
  • Module IDs
  • Dependencies
  • Implementation code
  • Original formatting (mostly)
• Supports filtering modules by include/exclude patterns
• Maintains directory structure based on module IDs
• Handles reserved keywords in code
• TypeScript support
