Dead Code Checker

Dead Code Checker is a tool for finding dead code in your JavaScript or TypeScript project. It helps to ensure a cleaner and more maintainable code base.

Features

• Variable Detection: Detects declared variables and verifies their usage.
• Function Detection: Identifies declared functions and checks if they are used across your project.
• Support any framework: React, Angular, Vue, and more.
• Detailed Report: Provides a detailed report of unused functions and variables, including the file and line number where they are declared.

Installation

You can install Dead Code Checker using npx:

npx dead-code-checker

To use Dead Code Checker, simply run the following command in your project directory:

npx dead-code-checker -f ./src

Option	Args	Description
-h, --help	null	Show all options.
-v, --version	null	Display Application Version: Displays the current version of the application.
-f, --folder	./src	Folder to be scanned: Folder to be scanned (Default: ./src)

The tool will recursively scan through your project's source files and generate a report of unused functions and variables.

Example Output

📁 File	🔢 Line	🔍 Name
/path/to/your/project/src/oneFile.js	17	myFunction
/path/to/your/project/src/twoFile.js	4	myVariable

If no unused functions or variables are found, you'll see a message like this:

✅ No dead code found!
