elasticsearchHow can I use Elasticsearch with Node.js?

Using Elasticsearch with Node.js is relatively straightforward. To get started, you'll need to install the Elasticsearch JavaScript client library. This can be done with the following command:

npm install elasticsearch

Once the library is installed, you can use it to connect to an Elasticsearch cluster. An example of how to do this is shown below:

const { Client } = require('elasticsearch');
const client = new Client({
  host: 'localhost:9200',
  log: 'trace'

Once the connection is established, you can use the client library to perform operations such as indexing, searching, and aggregations. For example, the following code snippet shows how to index a document:

  index: 'my-index',
  body: {
    title: 'My first document',
    content: 'This is my first document in Elasticsearch'
}, (err, resp, status) => {

The output of this code will be a JSON object containing the details of the indexed document.
