Worked on enhancing the Grafana plugin SDK Go repository by improving the creation and configuration of HTTP clients in Go. Developed a feature that ensures httpclient.New returns a distinct, default-configured HTTP client instance rather than relying on the global http.DefaultClient, increasing safety and configurability for backend development. Updated and expanded unit tests to verify the new behavior and improve test isolation, supporting more reliable and maintainable code. Focused on backend development, HTTP client implementation, and testing, the work addressed performance and reliability concerns by decoupling from shared global state, resulting in safer API usage and more predictable test outcomes.
