KV Storage

Operations

// Write with TTL (1 hour)
await env.FEED_CACHE.put(key, JSON.stringify(data), { expirationTtl: 3600 });

// Read
const cached = await env.FEED_CACHE.get(key, 'json');

// Delete
await env.FEED_CACHE.delete(key);

Key Concepts

• KV binding: Declared in wrangler.toml, accessed via env.NAMESPACE_NAME
• TTL and expiration: expirationTtl (seconds) or expiration (unix timestamp)
• Caching strategies: Cache-aside, write-through, TTL-based invalidation
• Namespace management: Separate namespaces for different data types
• Value types: text, json, arrayBuffer, stream
