import * as algoliasearchProxy from 'algoliasearch/index';
import * as encodeProxy from 'querystring-es3/encode';

import { VERSION } from './version';

const algoliasearch = algoliasearchProxy.default || algoliasearchProxy;
const encode = encodeProxy.default || encodeProxy;

export function createSSRAlgoliaClient({
  httpClient,
  HttpHeaders,
  transferState,
  makeStateKey,

  console.warn(
    '`createSSRAlgoliaClient` is deprecated in favor of `createSSRSearchClient` to be plugged to `searchClient`.'
  );

  return (_, appId, apiKey) =>

function sendPayload(fetchFn, trackerURL, payload) {
    const url = `${trackerURL}?${querystring.stringify(payload)}`;

}

index.reverse = function(options, callback) {
      var encoded = qs3.encode(options);

      return this.as._jsonRequest({
        method: 'GET',
        url: '/1/places/reverse?' + encoded,
        hostType: 'read',
        callback: callback
      });
