Connection handler for Amazon ES

Makes elasticsearch-js compatible with Amazon ES. It uses the aws-sdk to make signed requests to an Amazon ES endpoint.

Forked from https://github.com/TheDeveloper/http-aws-es which breaks when used with the latest elasticsearch library v16.7.2. This original repo seems to have\n
been abandoned with no PR in a long time.

Installation

``bash

Install the connector, elasticsearch client and aws-sdk

npm install --save @jwhance/http-aws-es aws-sdk elasticsearch
`

package.json

`
Something like this:

"dependencies": {
"@jwhance/http-aws-es": "6.1.2",
"aws-sdk": "2.831.0",
"elasticsearch": "16.7.2",

`

Usage

`javascript
// create an elasticsearch client for your Amazon ES
let es = require("elasticsearch").Client({
hosts: ["https://amazon-es-host.us-east-1.es.amazonaws.com"],
connectionClass: require("@jwhance/http-aws-es"),
});
`

Region + Credentials

The connector uses aws-sdk's default behaviour to obtain region + credentials from your environment. If you would like to set these manually, you can set them on aws-sdk:

`javascript
let AWS = require("aws-sdk");
AWS.config.update({
credentials: new AWS.Credentials(accessKeyId, secretAccessKey),
region: "us-east-1",
});
`

Options

`javascript
let options = {
hosts: [], // array of amazon es hosts (required)
connectionClass: require("http-aws-es"), // use this connector (required)
awsConfig: new AWS.Config({ region }), // set an aws config e.g. for multiple clients to different regions
httpOptions: {}, // set httpOptions on aws-sdk's request. default to aws-sdk's config.httpOptions
};
let es = require("elasticsearch").Client(options);
`

Test

`bash
npm test

test against a real endpoint

AWS_PROFILE=your-profile npm run integration-test -- --endpoint https://amazon-es-host.us-east-1.es.amazonaws.com --region us-east-1
