Use Cases
Team Avatar Cache
Download avatars for all team members:
for email in [email protected] [email protected] [email protected]; do
npx tsx scripts/download.ts "$email" "avatars/${email}.png" --size=400
doneProfile Image Backup
Save user avatars locally:
npx tsx scripts/download.ts [email protected] backup/maintainer.jpg --size=800Generate Placeholder Avatars
Create consistent default avatars:
npx tsx scripts/download.ts [email protected] user1.png --default=identicon
npx tsx scripts/download.ts [email protected] user2.png --default=identiconHigh-Resolution Display
Download retina-ready images:
npx tsx scripts/download.ts [email protected] [email protected] --size=400Caching
Downloaded images are cached for 24 hours:
- Same email + parameters = cached file returned
- Different parameters = new download
--no-cache= fresh download
This reduces API calls and bandwidth usage.
Error Handling
The script will fail if:
- Email is missing or invalid format
- Output file path is missing
- Network errors occur
- Disk write fails
Error messages indicate the specific failure for troubleshooting.
File Formats
Gravatar serves images in these formats:
- JPG - Smaller file size, good for photos
- PNG - Better for geometric/generated images (identicon, robohash)
- WebP - Modern format, smallest size (when supported)
The file extension in the output path determines the format saved.
