Master is using the agentkeepalive module that members of the community have had great success with for some time, but the library just updated to 3.0 and dropped support for Node.js version less than 4.0. I too would like to make that jump in elasticsearch-js, but I wonder how many people are using older versions. 馃憤 the version you use?
0.10
0.12
4.x
5/6.x
7.x
Node 6.9.5 and using 12.1.0-agentkeepalive branch
works like a charm
v6.4.0 and no problem so far
Thanks for the feedback everyone, plan for now is to make esjs v14.0 require 4.x
