On OSX with ElasticSearch server running in a docker container, I was getting the ECONNREFUSED error. I had mapped 9200 of the container to 9200 of the localhost and was trying to get to ElasticSearch through localhost:9200.

Just had to change the elastic search’s ip in my JS code directly to docker-machine’s ip which you can get using echo $(docker-machine ip) and it started working. Strange, but might solve someone’s problem if just wanna get it to work.

I’m using "elasticsearch": "11.0.1"

I wouldn’t suggest putting the master version of elasticsearch.js in your package.json. Master is regularly broken and should not be relied on.

As far as using nock with elasticsearch.js, I would suggest mocking out elasticsearch at a higher level. By using nock, you are testing all of the client code, which is unnecessary and error prone.

When I’m using elasticsearch.js in a project, I usually mock it out in my tests like this:

var client = require('../../elasticsearch-client');
var stub = require('sinon').stub;

describe('Some Module that uses elasticsearch', function () {
  beforeEach(function () {
    // stub the search method to return generic results
    stub(client, 'search', function (params, cb) {
      process.nextTick(function () {
        cb(null, {
          hits: { total: 121, hits: [ /* ... fake results ... */ ] }
        });
      });
    });
  });

  afterEach(function () {
    client.search.restore();
  });
});
