Fetch Elastic API with query Javascript

Question

i have elastic API and i try to fetch it with javascript and query on the fetch, but i don't know where to place the query, i only know how to fetch it just with authorization, can we fetch the elastic api with query ?

The Elastic Query:

GET http://192.168.150.155:9900/em-employeedata/_search
{
  "size": 10000,
  "query": {
    "match_all": {}
  }
}

The Javascript Code:

var url = 'http://192.168.150.155:9900/em-employeedata/_search/';

async function getapi(url) {

const response = await fetch(url, {method:'GET', 
headers: {'Authorization': 'Basic ' + btoa('em_user:3md@t@2o22')}})

var data = await response.json();

}

getapi(url);

You can use Elasticsearch Javascript client for same.

You can check this documentation where they have given example of Search.

Below is sample example:

const { Client } = require('@elastic/elasticsearch')
const client = new Client({
  cloud: { id: '<cloud-id>' },
  auth: { apiKey: 'base64EncodedKey' }
})

const result = await client.search({
    index: 'game-of-thrones',
    query: {
      match: {
        quote: 'winter'
      }
    }
  })

  console.log(result.hits.hits)

Above example show connecting using cloud_id and apiKey but there are other options also available. Please check this link.

If you are not using node.js then you can simply set fetch method to POST and pass body with json request.
