An Elasticsearch client for Swift based on SwiftNIO and AsyncHTTPClient. If you're interested in using this with AWS you may want to check out Soto Elasticsearch NIO Client.

First add the library as a dependency in your dependencies array in Package.swift:

.package(url: "https://github.com/brokenhandsio/elasticsearch-nio-client.git", from: "0.1.0"),

Then add the dependency to the target you require it in:

.target(
    name: "App",
    dependencies: [
        // ...
        .product(name: "ElasticsearchNIOClient", package: "elasticsearch-nio-client")
    ],
)

Creating an instance of ElasticsearchClient depends on your environment, but you should be able to work it out depending on what you need. For Vapor, for example, you'd do something like:

let elasticsearchClient = ElasticsearchClient(httpClient: req.application.http.client.shared, eventLoop: req.eventLoop, logger: req.logger, host: host)

Currently the library supports:

• Document create
• Document update
• Document delete
• Document search
• Document count
• Document retrieve
• Bulk create/update/delete/index
• Index delete
• Index exists
• Scripting

If you'd like to add extra functionality, either open an issue and raise a PR. Any contributions are gratefully accepted!

The library has been tested again Elasticsearch 8.4, but should work for the most part against older versions.
