v_jstools is a Chrome extension that enables rapid debugging of frontend JavaScript code by hooking into page APIs and injecting custom code during development.
The tool addresses the need to inspect and modify JavaScript behavior in running web applications without modifying source files. It works by allowing developers to hook into existing page APIs to monitor their behavior, inject custom JavaScript code that executes in the page context, generate JavaScript environment code for testing, and provide a toolkit for deeper JavaScript analysis. These capabilities operate through the extension's interface, which can be toggled on and off to enable or disable code injection.
Developers working on frontend debugging and JavaScript analysis should consider this tool if they need to quickly test code changes or inspect API calls during development. The extension requires Chrome version 105 or higher and operates under Manifest V3. Installation is straightforward, available either by downloading and extracting the repository locally or through a Python pip command-line utility that automates the extraction and file location opening.
The project maintains an active development cycle with regular updates and has undergone significant structural changes, including a migration from Manifest V2 to V3 with code refactoring. The tool includes a community discussion platform for users to share implementation approaches, practical use cases, and feedback on upcoming features.
