AWS ES Connection

AWS ES connection for the new elasticsearch client (@elastic/elasticsearch)

Usage

Javascript:

const { Client } = require('@elastic/elasticsearch');
const { createAWSConnection, awsCredsifyAll, awsGetCredentials } = require('@acuris/aws-es-connection')

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

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

Typescript:

import { createAWSConnection, awsCredsifyAll, awsGetCredentials } from '@acuris/aws-es-connection'
import AWS from 'aws-sdk'
import { Client } from '@elastic/elasticsearch'

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

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

How does it work?

This package has two parts. Firstly the createAWSConnection returns a class which signs the calls to AWS elasticsearch. The second part - awsCredsifyAll wraps the elastic search client so that all calls first check that the AWS credentials haven't expired 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 yarn test
