CLI Code Cleanup Library

Description

A command-line utility for analyzing JavaScript code, detecting unused variables and functions, and modifying code by listing, commenting, or deleting unused items based on the specified action.

Features

• List unused code: Identify unused variables and functions without modifying the original files.
• Comment unused code: Automatically add comments to unused variables and functions, making them easy to review.
• Delete unused code: Remove all unused variables and functions from the codebase for optimized, clean code.

Installation

Install the library globally or locally using npm:

# Globally

npm install -g code-sweep

# Locally (for project usage)

npm install code-sweep --save-dev

Usage

After installation, use the CLI tool by specifying a directory and action.

code-sweep -d <directory_path> -a <action>

CLI Options

-d, --directory <path> (required): Specifies the directory to analyze.
-a, --action <action> (required): Specifies the action to perform. Options:
list: List unused code without making changes.
comment: Add comments to unused code with // TODO: Unused Variable or // TODO: Unused Function.
delete: Remove unused code from the codebase.

Examples

List Unused Code

code-sweep -d src -a list

Lists all unused variables and functions in the src directory.

Comment Unused Code

# Adds comments to unused variables and functions in the src directory.

code-sweep -d src -a comment

Delete Unused Code

# Deletes unused variables and functions from files in the src directory.

code-sweep -d src -a delete

API

This library can also be used programmatically:

const { readDirectory, parseFileToAST, findUnused, commentCode, deleteCode } = require('code-sweep');

// Example: Read files in a directory and find unused code
const files = readDirectory('./src');
files.forEach((file) => {
  const ast = parseFileToAST(file);
  const unusedItems = findUnused(ast);
  console.log('Unused items:', unusedItems);
});
