Hi, Sorry to resurrect a somewhat old thread but it seemed the most logical place to ask this question: are there samples of setting up a client to use LB in various languages, specifically node.js? I believe its supported, but I can't figure out where I'm supposed to even start out at. It'd be nice to see a client that uses a naming resolver and load balancer, and perhaps a sample of writing one's own naming resolver and load balancer.
