wtf is metrics?

CocoaPods metrics is a tool that collects and serves usage statistics for CocoaPods, the popular package manager for Apple platform development. It powers the metrics website that lets developers see how widely a given library is being used across the ecosystem. The project does two main things. First, it pulls in raw usage data from Segment, a service that collects analytics events, and aggregates that data into meaningful statistics. Think of it as taking a firehose of individual data points and summarizing them into useful numbers. Second, it can run as an API, which is essentially a backend service that other applications or websites can query to retrieve those compiled metrics on demand. The primary audience is the CocoaPods community itself. Library authors who publish their code through CocoaPods would use the resulting data to understand adoption trends, such as how many projects depend on their library over time. The broader developer community benefits as well, since these metrics help teams evaluate which libraries are well-maintained and widely trusted before choosing to adopt them. The README is notably sparse and does not go into detail about the specific metrics being tracked, the API endpoints available, or how to deploy the tool. It is labeled as a work-in-progress version of the existing metrics site, written in Go. Beyond the two core functions of aggregating Segment data and serving as an API, the documentation does not provide further guidance on setup or configuration.
