Description

Run JTMetrics on GitHub repositories and download JSON results. JTMetrics is a lightweight and extensible library for calculating code metrics in JavaScript and TypeScript repositories. Author: Daniel Zazzali (https://www.npmjs.com/package/jtmetrics). To support the practical adoption of JTMetrics, we implemented a Chrome Extension that embeds the tool into GitHub through a dedicated JTMetrics tab on repository pages. By integrating metric access into a familiar platform, the extension lets you analyze JavaScript and TypeScript repositories in situ, improving usability and connecting software metric analysis to everyday development.
