What's Your Libscore?

Libscore is an open-source project that scans the top million websites to determine which third-party JavaScript libraries they are using. The tool aims to help front-end open source developers measure their impact. To achieve this, Libscore uses a headless browser to thoroughly scan each website's run-time environment and detect as many libraries as possible. The technology leverages meta-heuristics to weed out false positives for third-party plugins. On the backend, crawls are queued via Redis with results stored in MongoDB, allowing for fast RESTful API serving. The project has faced challenges, including memory constraints, but is expected to provide valuable insights into library usage and adoption trends, as well as serve as a data store for open source projects.
