Create React App Boilerplate

In this quickstart guide, we will create a books based search engine based on a dataset of 10,000 books using ReactiveSearch.

This is how your final app will look like at the end of following this tutorial, in just 10 minutes 🚀

We can either add ReactiveSearch to an existing app or create a boilerplate app with Create React App (CRA). For this quickstart guide, we will use the CRA.

create-react-app my-awesome-search && cd my-awesome-search


Alternatively, you can go to and choose the React Template

React Template, Codesandbox

Step 1: Install ReactiveSearch

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

yarn add @appbaseio/reactivesearch


npm install @appbaseio/reactivesearch


Alternatively, you can directly add the @appbaseio/reactivesearch dependency to

Step 2: Adding the first component

Lets add our first ReactiveSearch component: ReactiveBase, it is a provider component that allows specifying the Elasticsearch index to connect to. Here, we will be using an Elasticsearch instance hosted with Sign up here to create your cluster. If you already have an Elasticsearch cluster setup, you can see this guide on how to connect to it.

create an index

Caption: For the example that we will build in this tutorial, the app is called good-books-ds and the associated read-only credentials are 04717bb076f7:be54685e-db84-4243-975b-5b32ee241d31. You can browse and export the dataset to JSON or CSV from here.

Note: Clone app option will not work with these credentials here have very narrow access scope (to prevent abuse).

We will update our src/App.js file to add ReactiveBase component.

import React from "react";
import { ReactiveBase } from "@appbaseio/reactivesearch";

function App() {
  return (
      {/* Our components will go over here */}
      Hello from ReactiveSearch 👋

export default App;

This is how the app should look after running the yarn start command.

Step 3: Adding Search and Aggregation components

For this app, we will be using SearchBox, MultiList and SingleRange components for searching and filtering on the index. And ResultCard component for showing the search results.

Lets add them within the ReactiveBase component. But before we do that, we will look at the important props for each.

			"field": "authors",
			"weight": 3
			"field": "authors.autosuggest",
			"weight": 1
			"field": "original_title",
			"weight": 5
			"field": "original_title.autosuggest",
			"weight": 1
	placeholder="Search for books or authors"

The SearchBox component creates a searchbox UI component that queries on the specified fields with weights as specified by dataField prop. That's all it takes to create a functional search component.

At this point, you should see the following:


Next, we will add the MultiList component. As the name suggests, it creates a multiple selection aggregation (aka facet) to filter our search results by.

	title="Filter by Authors"

Aggregation components like MultiList fire a term type query. You can think of a term query as an exact match query, unlike a search query which involves more nuances. The use of the .keyword suffix for the authors field informs the search engine that the query here is of an exact type.

The aggregationSize prop is used to specify the total aggregations (think buckets) that you want returned based on the dataField value.

Note: The dataField value in MultiList is of string type, since an aggregation is always performed on a single field. In contrast, you may want to search on multiple fields in different ways, so the SearchBox component uses an array of fields instead.


Next, we will add the SingleRange component for creating a ratings based filter for our book search.

	title="Filter by Ratings"
		{ start: 4, end: 5, label: '4 stars and up' },
		{ start: 3, end: 5, label: '3 stars and up' },
	defaultValue="4 stars and up"

The SingleRange operates on a numeric datatype field and fires a range query. The data prop of SingleRange allows specifying a [start, end] range and a label associated with it. Using defaultValue, we can preselect a particular option. In this case, we're preselecting all the books that have a rating of 4 stars and up.

At this point, this is how our app should be looking:

We just added completely functional search and aggregation components!

Step 4: Adding Results Component

We just need a results component to display the books that we're searching for. We will use the ReactiveList component with the ResultCard preset.

		and: ["searchbox", "authorsfilter", "ratingsfilter"]
	render={({ data }) => (
		{ => (
			<ResultCard key={item._id}>
			<ResultCard.Image src={item.image} />
				__html: item.original_title
				{item.authors + " " + "*".repeat(item.average_rating)}

The react prop here specifies that the result should depend on the queries for our searchbox, authors filter and the ratings filter. It's pretty neat!

In the render method, we are using the ResultCard preset to iterate over each result (aka hit) and set the image, title and description values of the card layout.

At this point, you should be seeing our entire app functionally (minus the layouting and styles):

We have built our entire search UI in just 60 lines of code!

Step 5: Adding Layout and Styles

ReactiveSearch doesn't use a layout system internally. If you are using a grid from Bootstrap or Materialize, you can use that. Here, will just make use of CSS Flex.

If you are new to Flex, we recommend a quick read of this article.

With ~6 more lines, our final app layout looks as follows.

	<div style={{ display: "flex", flexDirection: "row" }}>
		<div style={{ display: "flex", flexDirection: "column", width: "30%", margin: "10px" }}>
		<div style={{ display: "flex", flexDirection: "column", width: "66%" }}>
			<SearchBox />

Add some margins between the search and result component, and voila! Our final app is ready:
