AWS ES Connection

This is a form from the acuris-aws-es-connection modified to work with the AWS Opensearch Service

AWS ES connection for the new opensearch client (@opensearch-project/opensearch)

Usage

Javascript:

const { Client } = require('@opensearch-project/opensearch')
const { createAWSConnection, awsGetCredentials } = require('aws-opensearch-connection')

const awsCredentials = await awsGetCredentials()
const AWSConnection = createAWSConnection(awsCredentials)
const client = new Client({
  ...AWSConnection,
  node: 'https://node-name.eu-west-1.es.amazonaws.com'
})

// inside async func
await client.cat.help()

Typescript:

import { createAWSConnection, awsGetCredentials } from 'aws-opensearch-connection'
import AWS from 'aws-sdk'
import { Client } from '@opensearch-project/opensearch'

const awsCredentials = await awsGetCredentials()
const AWSConnection = createAWSConnection(awsCredentials)
const client = new Client({
  ...AWSConnection,
  node: 'https://node-name.eu-west-1.es.amazonaws.com'
})

// inside async func
await client.cat.help()

How does it work?

This package creates a Connection class that signs the requests to AWS elasticsearch and a Transport class that checks that the AWS credentials haven't expired before every call, and refreshes them when needed.

Developer notes

Running the tests.

Make sure that your AWS credentials are available to your env, for example you could set them in your ENV.

You need a running AWS ES instance for the tests to run against. Set the endpoint URL as the env AWS_ES_ENDPOINT.

AWS_ES_ENDPOINT=https://xxxx.es.amazonaws.com npm test

Tested versions

This package has been tested on versions of the official elasticsearch client up to 7.13.0.
