package-detector

Package Detector is a performance-focused CLI for auditing your project’s dependencies. It scans your codebase to flag truly unused packages (while recognizing infrastructure packages like build tools and test frameworks), checks for outdated versions, detects duplicates in the tree, and identifies heavy packages that may bloat bundles. It includes optional GitHub integration to analyze repos and auto-create dependency update PRs with custom labels, reviewers, and commit messages. The tool is optimized with caching, parallel processing, depth-limited traversal, precompiled regexes, early termination, and rate-limited API calls (e.g., for Bundlephobia). It supports common project structures out of the box, excludes typical build/output directories, and requires no configuration for most use cases. Typical runs on mid-sized projects finish quickly, with substantial speedups from caching and batch operations.
