# ai-python-ui-adapter
Frontend:
```tsx
const chat = useChat({
transport: new DefaultChatTransport({ api: "/api/chat" }),
sendAutomaticallyWhen: lastAssistantMessageIsCompleteWithApprovalResponses,
});
```
Use `chat.sendMessage(...)` to send user input. Use
`chat.addToolApprovalResponse(...)` from approval buttons.
Backend request:
```python
class ChatRequest(pydantic.BaseModel):
messages: list[ai.agents.ui.ai_sdk.UIMessage]
messages, approvals = ai.agents.ui.ai_sdk.to_messages(request.messages)
ai.agents.ui.ai_sdk.apply_approvals(approvals)
```
Backend stream:
```python
async def body():
async with agent.run(model, messages) as stream:
async def events():
async for event in stream:
if (
isinstance(event, ai.events.HookEvent)
and event.hook.status == "pending"
):
ai.defer_hook(event.hook)
yield event
async for chunk in ai.agents.ui.ai_sdk.to_sse(events()):
yield chunk
return StreamingResponse(
body(),
headers=ai.agents.ui.ai_sdk.UI_MESSAGE_STREAM_HEADERS,
)
```
The adapter handles `UIMessage` parsing, message IDs, tool state, approvals,
subagent `MessageBundle` values, and AI SDK UI stream events.
You handle the HTTP route, auth, storage, session lookup, frontend rendering,
and when to defer hooks.
For saved UI history, use:
```python
ui_messages = ai.agents.ui.ai_sdk.to_ui_messages(messages)
```
