Signature

function withSSEHandle(fetchImpl: FetchHandle): ClientOption;

The default is the platform fetch. fetchImpl is a FetchHandle. It only affects SSE. HTTP uses withHTTPHandle.

Prop

Type

fetchImpl FetchHandle

(input, init?) => Promise<Response>. Not typeof fetch, so a mock does not need host extras such as preconnect.

An option that sets config.sse.handle.

withQuerySerializer

Replaces query encoding for HTTP, SSE, and WebSocket requests.

withSSEOnInvalidEvent

Observes SSE events that have no matching event struct or fail validation.
