How does this skill assist with migrations?

It provides standardized configuration snippets for wrangler.jsonc to handle new class creation, renaming, and SQLite backend migrations safely.

Can I use RPC instead of HTTP fetch for communication?

Absolutely. The skill prioritizes the modern RPC (Remote Procedure Call) pattern for simpler, type-safe interactions between your Workers and Durable Objects.

What storage backends are supported by this skill?

The skill provides patterns for both the recommended SQLite backend (supporting up to 10GB) and the standard Key-Value (KV) storage API.

Is this skill updated for the latest 2025 Cloudflare features?

Yes, it includes 2025 updates such as the getByName() API shortcut, 32MB WebSocket message limits, and Python Workers support.

Does this skill handle WebSocket hibernation?

Yes, it includes specific patterns for using ctx.acceptWebSocket() and serializeAttachment() to ensure session state persists across hibernation cycles.
