FAQPage Schema

How do I implement chat with AI SDK v5?▼

Chat integration with AI SDK v5 uses the useChat hook paired with DefaultChatTransport to wire client-server communication. This pattern handles message state, streaming responses, and tool calls end-to-end without manual transport setup.

What are UIMessage parts and how do I use them?▼

UIMessage parts let you render mixed content—text, UI components, and tool outputs—within a single message. AI SDK v5 standardizes their structure across client and server, enabling rich, interactive chat experiences with proper serialization.

How do I migrate from AI SDK v4 to v5?▼

Migration involves updating chat patterns, streaming transports, and tool-call workflows to v5 conventions. This Skill provides side-by-side v4 and v5 examples showing route handlers, client setup, and UIMessage structures for practical porting.

Can I use tool calls with streaming in AI SDK v5?▼

Yes. AI SDK v5 integrates tool-call workflows with streaming transports, allowing the server to emit tool invocations and results within a streamed response. The Skill demonstrates complete end-to-end tool integration patterns.

What transport setup do I need for streaming chat?▼

DefaultChatTransport handles streaming transport configuration for useChat. It manages request serialization, response streaming, and error handling, eliminating manual transport wiring for typical chat and tool-call scenarios.
