How anuragbiradar2305/npm-package-diff works
Get Package Diff is a small Express API that accepts a package name and two versions, validates their order, retrieves NPM metadata, compares the versions’ dependencies, and returns available GitHub release details and a comparison link. The runtime is implemented in server.js; the tree shows no separate service modules. The GitHub comparison link is constructed locally, while release details are fetched from GitHub. The graph reflects these documented capabilities and the sampled route implementation.
Main entry points: server.js GET /diff
