Code Review

This pull request adds a new /api/health endpoint to check the application's status. The feedback suggests enhancing this health check by verifying the database connection state and returning a 503 status if the database is disconnected, rather than unconditionally returning a 200 OK status.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.

A robust health check should verify the status of critical dependencies like the database connection. Currently, the route returns 200 OK even if the database connection is lost or disconnected. Checking mongoose.connection.readyState ensures that orchestrators (like Kubernetes or AWS ECS) or load balancers can accurately detect when the service is unhealthy and take appropriate action (e.g., restarting the container or stopping traffic routing).

Suggested change

	const express=require('express')
	const router=express.Router()
	router.get('',(req,res)=>{
	res.status(200).json({ status: 'ok' })
	})
	module.exports = router
	const express = require('express')
	const { default: mongoose } = require('mongoose')
	const router = express.Router()
	router.get('', (req, res) => {
	const dbState = mongoose.connection.readyState
	if (dbState !== 1) {
	return res.status(503).json({
	status: 'error',
	database: 'disconnected'
	})
	}
	res.status(200).json({ status: 'ok' })
	})
	module.exports = router
