📝 Walkthrough

Walkthrough

Adds a /health GET endpoint to server.js returning runtime diagnostics (uptime, timestamp, memory usage) with HTTP 200/503 status. Creates utils/keepServer.js to ping that endpoint via axios every 45 minutes. Adds axios to dependencies. Mounts /products in app.js and refactors product tests to use the shared app instance.

Changes

Health Check Infrastructure and Products Route Wiring

Layer / File(s)	Summary
/health endpoint and keepServer periodic utility server.js, utils/keepServer.js, package.json	server.js adds a /health GET route returning status, uptime, timestamp, and memoryUsage (HTTP 200), falling back to status: 'DOWN' with HTTP 503 on error. utils/keepServer.js is created to run an axios GET against HEALTH_CHECK_URL every 45 minutes, logging either the response data or 'Server is down'. axios ^1.18.0 is added to package.json.
/products route wiring and test refactor app.js, test/product.test.js	app.js registers productRoutes at /products. product.test.js removes inline Express app construction and mounts, replacing them with an import of the shared app from ../app.

Poem

🐇 Hippity-hop, the server's alive,
A /health endpoint helps it survive!
Every 45 minutes, a ping goes out,
keepServer checks what it's all about.
Products now routed, tests neat and trim —
This bunny keeps servers from going dim! 🌟
