Ops: Verify Health
Health check all services across environments.
Argument: $ARGUMENTS — environment(s) to check (default: all). Options: local, dev, staging, production, all
Discovery
Read these files to build the environment URL table:
e2e/constants.ts— frontend URLs per environment.env.localhost,.env.development,.env.staging,.env.production—EXPO_PUBLIC_GRAPHQL_BASE_URLfor backend GraphQL URLs
Health Checks
For each environment, run these checks:
Frontend Check
curl -sf -o /dev/null -w "HTTP %{http_code} in %{time_total}s" {frontend_url}
Verify the response contains Expo/React markers:
curl -sf {frontend_url} | head -20
Backend GraphQL Check
curl -sf {graphql_url} -X POST \
-H "Content-Type: application/json" \
-d '{"query":"{ __typename }"}' \
-w "\nHTTP %{http_code} in %{time_total}s\n"
GraphQL Introspection (detailed check)
curl -sf {graphql_url} -X POST \
-H "Content-Type: application/json" \
-d '{"query":"{ __schema { queryType { name } } }"}' \
-w "\nHTTP %{http_code} in %{time_total}s\n"
Full Health Check Script
Run all checks for the specified environment(s):
check_env() {
local ENV=$1
local FE_URL=$2
local BE_URL=$3
echo "=== $ENV ==="
# Frontend
FE_STATUS=$(curl -sf -o /dev/null -w "%{http_code}" --max-time 10 "$FE_URL" 2>/dev/null || echo "000")
FE_TIME=$(curl -sf -o /dev/null -w "%{time_total}" --max-time 10 "$FE_URL" 2>/dev/null || echo "timeout")
echo "Frontend: HTTP $FE_STATUS ($FE_TIME s)"
# Backend
BE_RESULT=$(curl -sf --max-time 10 "$BE_URL" -X POST \
-H "Content-Type: application/json" \
-d '{"query":"{ __typename }"}' \
-w "\n%{http_code} %{time_total}" 2>/dev/null || echo -e "\n000 timeout")
BE_STATUS=$(echo "$BE_RESULT" | tail -1 | awk '{print $1}')
BE_TIME=$(echo "$BE_RESULT" | tail -1 | awk '{print $2}')
echo "Backend: HTTP $BE_STATUS ($BE_TIME s)"
echo ""
}
EAS Update Status
Check the latest OTA updates deployed to each branch:
eas update:list --branch {env} --limit 3
Output Format
Report results as a table:
| Service | Environment | Status | Response Time | Details |
|---|---|---|---|---|
| Frontend | dev | UP (200) | 0.45s | HTML contains React root |
| Backend | dev | UP (200) | 0.32s | GraphQL responds __typename |
Flag any service with status != 200 or response time > 5s as a concern.
