Download Trends
The data can show:
- Weekly patterns - Higher weekday downloads for development tools
- Release spikes - Sudden increases after major version releases
- Seasonal trends - Patterns based on project cycles
- Long-term growth - Overall adoption trends
Caching
Download statistics are cached for 24 hours. Historical download data doesn't change, so the cache provides the same data with better performance.
Use the --no-cache flag to bypass the cache.

Error Handling
Package not found: Download stats are only available for published packages. Use npm-exists to verify the package exists first.
Invalid period: Ensure the period format is correct. Date ranges must use colons to separate dates from the package name.
No data: Very new packages may not have download statistics yet. Statistics are typically available within 24-48 hours of first publish.
Data Limitations
- Delay: Download counts are typically 24-48 hours behind
- Granularity: Data is available per day, not per hour
- Scope: Counts include all download sources (npm install, CDN, mirrors)
- Accuracy: Numbers are approximate and may include failed downloads
