js-module-extractor

js-module-extractor is a lightweight Python CLI tool that extracts and beautifies JavaScript modules from a plain text file. It scans for lines using the pattern __d("moduleName", ...), extracts the module name, formats the code, and writes each module to a separate .js file.

Features

• Detects JavaScript module definitions in __d("...") format
• Extracts and saves each module into its own file
• Beautifies the code using jsbeautifier
• CLI usage via js-module-extractor command

Installation

Install directly from the GitHub repository:

pip install git+https://github.com/maxipalacios/js-module-extractor.git

Usage

After installing, you can run it from the command line:

js-module-extractor input_file.txt

• input_file.txt: A UTF-8 encoded text file with one or more __d("moduleName", ...) lines.

Output

The tool will create a folder named output_modules/ (if not already present) and generate one file per module:

output_modules/
└── MyModule.js

Each file contains beautified code extracted from the original input.

Example

Input line:

__d("MyModule", function(global, require, module, exports) { /* code */ }, 123);

Command:

js-module-extractor modules.txt

Result:

output_modules/
└── MyModule.js
