People searching “Laravel AI SDK stream Vue” return stream() from the Inertia form action and the visit fails. A stream is not an Inertia redirect. The AI SDK guide posts a note and redirects with the finished string. Use that when the reply is short. Use a stream route when you need tokens as they arrive.
TL;DR
- stream() can be returned from its own route as server-sent events.
- It is not an Inertia form response.
- Do not put the provider key in the fetch URL.
- Do not point
<Form>at this route and expect the slot’s errors to render the tokens.
The fix#
Route::post('/replies/stream', function (Request $request) {
$validated = $request->validate([
'note' => ['required', 'string', 'max:2000'],
]);
return (new DraftReply)->stream($validated['note']);
})->middleware('auth');The Vue page starts that request with fetch, not with useForm. useForm is waiting for a redirect and an Inertia page. The auth middleware stays. A public stream is a public bill.
What to avoid#
Gotcha
Do not put the provider key in the fetch URL. Do not point <Form> at this route and expect the slot’s errors to render the tokens. Validation errors from this route are a normal HTTP response, which your fetch has to read.
