expose a lightweight /healthz endpoint #33
Description
📝 Description
To improve observability and Kubernetes readiness, we should expose a lightweight /healthz endpoint that returns a simple 200 OK status. This helps in:
Readiness/liveness probes in orchestration environments
Health checks for load balancers or monitoring tools
CI tests verifying server availability
✅ Acceptance Criteria
Add a new route /healthz that:
Responds to GET
Returns HTTP 200 with body "OK\n"
Ensure no query parameters are needed
Add unit test to verify:
Status code is 200
Response body is "OK\n"
Add log entry for /healthz requests (optional)
🧩 Notes
This is a simple change that touches routing, handler creation, and test writing. It’s ideal for testing Copilot’s ability to:
Scaffold new routes in a Go web server
Write HTTP tests
Recognize standard health check patterns
No external dependencies are required. Low effort, high visibility.
