Basic HTTP Request

This feature allows you to make basic HTTP requests to an Elasticsearch cluster. The code sample demonstrates how to create a Transport instance and make a GET request to the root endpoint of the Elasticsearch cluster.

const { Transport } = require('@elastic/transport');

const transport = new Transport({
  node: 'http://localhost:9200'
});

async function makeRequest() {
  const response = await transport.request({
    method: 'GET',
    path: '/'
  });
  console.log(response.body);
}

makeRequest();

Handling Retries

This feature allows you to configure the number of retries for failed requests. The code sample demonstrates how to set up a Transport instance with a maximum of 3 retries and handle the request failure.

const { Transport } = require('@elastic/transport');

const transport = new Transport({
  node: 'http://localhost:9200',
  maxRetries: 3
});

async function makeRequest() {
  try {
    const response = await transport.request({
      method: 'GET',
      path: '/'
    });
    console.log(response.body);
  } catch (error) {
    console.error('Request failed after 3 retries:', error);
  }
}

makeRequest();

Connection Pooling

This feature allows you to manage multiple connections to different nodes in an Elasticsearch cluster. The code sample demonstrates how to create a Transport instance with a pool of nodes and make a request.

const { Transport } = require('@elastic/transport');

const transport = new Transport({
  nodes: [
    'http://localhost:9200',
    'http://localhost:9201'
  ]
});

async function makeRequest() {
  const response = await transport.request({
    method: 'GET',
    path: '/'
  });
  console.log(response.body);
}

makeRequest();
