Browser Tab Debugger

Execute JavaScript files on Chrome tabs via remote debugging.

Setup

1. Install dependencies:

npm install

2. Start Chrome with remote debugging enabled:

chrome.exe --remote-debugging-port=9222

Or on Windows, run from PowerShell:

& "C:\Program Files\Google\Chrome\Application\chrome.exe" --remote-debugging-port=9222

Usage

Option 1: VS Code Debug Configuration

1. Open the JavaScript file you want to execute (e.g., example.js)
2. Press F5 or go to Run and Debug
3. Select "Execute Script on Current Tab"
4. The script will run on the currently active Chrome tab

Option 2: Command Line

node run-script.js example.js

How it works

The script connects to Chrome's DevTools Protocol on port 9222, finds the first active page tab, and executes your JavaScript code using Runtime.evaluate.
