Using the REST API it is possible to determine the server version number (in this case "7.10.2")

curl 'https://search-elasticsearch-aws-710-public-v7fycso36gekt3vjabelkne2fa.eu-west-1.es.amazonaws.com'
{
  "name" : "3af17e13e3e29b64cd0f32c57edadc0e",
  "cluster_name" : "206020203570:elasticsearch-aws-710-public",
  "cluster_uuid" : "i19BVkuJTjmivIeg0VRWwA",
  "version" : {
    "number" : "7.10.2",
    "build_flavor" : "oss",
    "build_type" : "tar",
    "build_hash" : "unknown",
    "build_date" : "2021-07-20T13:48:00.963660Z",
    "build_snapshot" : false,
    "lucene_version" : "8.7.0",
    "minimum_wire_compatibility_version" : "6.8.0",
    "minimum_index_compatibility_version" : "6.0.0-beta1"
  },
  "tagline" : "You Know, for Search"
}

Is it possible to return the same information using only the @elastic/elasticsearch js library?

Figured it out!

• https://www.elastic.co/guide/en/elasticsearch/client/javascript-api/current/api-reference.html#_info

const elasticsearch = require('@elastic/elasticsearch');
const client = new elasticsearch.Client(options);
client.info().then(info => {
    console.log(info);
});
