consul-node

A node.js client library for consul

This module attempts to be "low level" and follows consul's API pretty closely, meaning not a whole lot of sugar is provided for you. If you need something small, sugary and focused, use this module to build something higher level.

Warning

This not stable because is still being developed, feel free to help out!
