Communicate with AWS Elasticsearch.


Other solutions for communicating with Elasticsearch are either incompatible with AWS, very heavy weight, or both. This client gets the job done and is as simple as it gets!

  • Simple Promise or async syntax
  • Authenticates to AWS via AWS Signature v4
  • Light-weight

Use it with Elasticsearch’s Document API.

ElasticsearchClient depends on two other utilities to work:


npm install @sailplane/elasticsearch-client @sailplane/aws-https @sailplane/logger


Simple example:

get(id: string): Promise<Ticket> {
    return this.es.request('GET', '/ticket/local/' + id)
        .then((esDoc: ElasticsearchResult) => esDoc._source as Ticket);

See More Examples for a comprehensive example.

Type Declarations

import { AwsHttps } from "@sailplane/aws-https";
 * All-inclusive possible properties of returned results from ElasticsearchClient
export interface ElasticsearchResult {
    _shards?: {
        total: number;
        successful: number;
        failed: number;
        skipped?: number;
    _index?: string;
    _type?: string;
    _id?: string;
    _version?: number;
    result?: "created" | "deleted" | "noop";
    found?: boolean;
    _source?: any;
    took?: number;
    timed_out?: boolean;
    hits?: {
        total: number;
        max_score: number | null;
        hits?: [{
            _index: string;
            _type: string;
            _id: string;
            _score: number;
            _source?: any;
    deleted?: number;
    failures?: any[];
 * Lightweight Elasticsearch client for AWS.
 * Suggested use with Injector:
 *   Injector.register(ElasticsearchClient, () => {
 *     const endpoint: string = process.env.ES_ENDPOINT!;
 *     logger.info('Connecting to Elasticsearch @ ' + endpoint);
 *     return new ElasticsearchClient(new AwsHttps(), endpoint);
 *  });
export declare class ElasticsearchClient {
    private readonly awsHttps;
    private readonly endpoint;
     * Construct.
     * @param awsHttps injection of AwsHttps object to use.
     * @param {string} endpoint Elasticsearch endpoint host name
    constructor(awsHttps: AwsHttps, endpoint: string);
     * Send a request to Elasticsearch.
     * @param {"GET" | "DELETE" | "PUT" | "POST"} method
     * @param {string} path per Elasticsearch Document API
     * @param {any?} body request content as object, if any for the API
     * @returns {Promise<ElasticsearchResult>} response from Elasticsearch. An HTTP 404
     *              response is translated into an ElasticsearchResult with found=false
     * @throws {Error{message,status,statusCode}} error if HTTP result is not 2xx or 404
     *              or unable to parse response. Compatible with http-errors package.
    request(method: 'DELETE' | 'GET' | 'PUT' | 'POST', path: string, body?: any): Promise<ElasticsearchResult>;
