Cloudflare cache invalidation can be done through the Cloudflare dashboard, API, or using the Cloudflare CLI. The easiest method is to 'Purge Cache' in Cloudflare dashboard. Select 'Purge Everything' to clear the entire cache or 'Custom Purge' to invalidate specific files using URLs or prefixes. You can integrate the Cloudflare API into your deployment process to automatically purge the cache when files are updated in S3.
