Streaming

When streaming is enabled, the endpoint will emit events “answer” (answer of the model) and “endpoint_response” (full response of the endpoint)
import {
  EventStreamContentType,
  fetchEventSource,
} from '@microsoft/fetch-event-source';

let buffer = '';
let bufferEndpointResponse = '';
const ctrl = new AbortController();

await fetchEventSource(queryAgentURL, {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json',
        },
        signal: ctrl.signal,
        body: JSON.stringify({
          streaming: true,
          query,
          conversationId,
          visitorId,
        }),

        async onopen(response) {
          if (response.status === 402) {
            throw new ApiError(ApiErrorType.USAGE_LIMIT);
          }
        },
        onmessage: (event) => {
          if (event.data === '[DONE]') {
            // End of stream
            ctrl.abort();

            try {
              const { sources, conversationId, visitorId } = JSON.parse(
                bufferEndpointResponse
              ) as ChatResponse;
            } catch {}
