ReactiveSearch App

We can either add ReactiveSearch to an existing app or create a boilerplate app with Create React App (CRA):

create-react-app search-app && cd search-app

Install ReactiveSearch

We will fetch and install reactivesearch module using yarn or npm.

npm install @appbaseio/reactivesearch

Building your App

Lets add our first ReactiveSearch component: ReactiveBase, it is a backend connector where we can configure the Elasticsearch index / authorization setup.

We will update our src/App.js file to add ReactiveBase component and connect them to our local instance of Elasticsearch 7.8:

import React, { Component } from "react";

import {
  ReactiveBase,
  CategorySearch,
  SelectedFilters,
  ReactiveList,
  SingleList,
  MultiList,
  ResultList,
} from "@appbaseio/reactivesearch";

const { ResultListWrapper } = ReactiveList;

const flexBox = {
  display: "flex",
  marginTop: 20,
};

const flexColumn = {
  flexDirection: "row",
};

const tagsSelector = {
  minHeight: "100%",
};

class App extends Component {
  render() {
    return (
      <ReactiveBase url="http://localhost:9200" app="wiki_ssr_en_2020_07_06">
        <CategorySearch
