Including Elasticsearch in Ember-CLI application

Question

I am new to Ember and Node, and I would like to use Elasticsearch with Ember.

I'm using the npm elasticsearch package.

From what I gather, I should inject ES as a service, but I'm not sure where to include the ES initialization code and register the client with the Ember app.

var elasticsearch = require('elasticsearch');
var client = new elasticsearch.Client({
    host: 'localhost:9200',
    log: 'trace'
});`

All I've got right now is ember g service elasticsearch

I appreciate the help for a noob!

You seem to want to use the elastic search client directly in your ember application (correct me if I am wrong). Unfortunately, you cannot use the node module directly within ember so you will need to architecture your application differently.

You have a few options:

1) Use a library like Ember Data Adapter for elasticsearch or ember-data-elasticsearch-kit in your ember application (which will run in the browser) to query elastic search. (I picked these since they were the first results in Google - they seem to be a bit out of date, but perhaps you can find something with more recent updates.)

2) Create an API endpoint with node (and perhaps something like Express ) and use the elasticsearch module and elastic search client to query elastic search on the server and return JSON which you can consume in your ember application. So, for instance:

    $.ajax({
       url: 'UrlOfMethodExposedByNode',
       type: 'GET',
       accepts: 'application/json',
       success: function(data) {
           // you can use the data here to set a value on a controller, etc
       },
       error: function() {
           // something went wrong while retrieving data from your API
       }
   });

More details will depend on the specifics of your application.
