What is a Cloudflare Durable Object?

A specialized Cloudflare Worker class that provides a unique point of coordination and persistent state for distributed applications, ensuring only one instance exists for a given ID.

Can I use SQLite with Durable Objects?

Yes, this skill includes the latest 2025 patterns for the SQLite backend, supporting up to 10GB of storage and full SQL query capabilities per object.

Why use RPC over HTTP fetch for Durable Objects?

RPC is the recommended modern approach as it allows for direct, type-safe method calls between Workers and Durable Objects without the overhead of manual HTTP routing.

How does this skill handle WebSocket hibernation?

It provides patterns for using ctx.acceptWebSocket() and serializeAttachment() to maintain state and connectivity while saving costs during idle periods.

Does this skill prevent common deployment errors?

Yes, it specifically checks for and prevents over 20 documented errors related to missing exports, binding mismatches, and incorrect migration tags.
