Cloudflare R2

Use S3-compatible object storage without egress fees.

Setup

# Create bucket
npx wrangler r2 bucket create app-assets

# List buckets
npx wrangler r2 bucket list

# Upload object
npx wrangler r2 object put app-assets/logo.png --file ./logo.png

S3-Compatible Access

• Generate R2 API tokens with least privilege.
• Use endpoint format: https://<accountid>.r2.cloudflarestorage.com.
• Configure lifecycle rules for archive/delete.

Best Practices

• Use short-lived signed URLs for private content.
• Store user uploads in tenant-specific prefixes.
• Enable object versioning for recovery-critical buckets.
