How It Works

Runtime architecture explained for application developers.

You do not need to understand the runtime internals to send messages or render React chat. These pages explain the architecture so you can debug production behavior, choose providers, write custom transports, and reason about reliability.

The short version:

messages and queued items are durable
storage is authoritative
ThreadState is the app projection
streams are live mechanisms
providers implement narrow contracts

Read these after Getting Started and Concepts.

Provider Implementations

Conformance expectations for custom storage, realtime, and file providers.

Runtime Pipeline

What happens after a client sends a message or action.
