I was running Graylog with ES5.x and used aggregations and d3 to cre3ate visualization.
I uninstalled Graylog (and ES) and installed ES 6.2.4. (no Graylog)
What do I need to do with elasticsearch.js that I was using on the client? Is there a new version to use for the client? Where can I find this?
I have been looking here https://www.elastic.co/guide/en/elasticsearch/client/javascript-api/current/index.html
Thanks
