When no Gravatar found:
Checking: nonexistent@example.com
✗ No Gravatar found
Hash: abc123def456789...
This email does not have a Gravatar image.
A default image will be shown.
Check if developer has Gravatar:
npx tsx scripts/check.ts beau@dentedreality.com.au
Bypass cache for fresh check:
npx tsx scripts/check.ts user@example.com --no-cache
Check if an email is associated with a Gravatar profile:
npx tsx scripts/check.ts contact@company.com
Check multiple team members:
for email in dev1@company.com dev2@company.com; do
npx tsx scripts/check.ts "$email"
done
Verify Gravatar exists before displaying avatar in UI:
npx tsx scripts/check.ts user@example.com && echo "Show Gravatar" || echo "Show default"
Results are cached for 24 hours. Since Gravatars change infrequently, caching improves performance while maintaining accuracy.
Use --no-cache when you need real-time verification.
