              It seems that you are running a cluster with {this.state.nodes.length} nodes. For CouchDB 2.0
              we recommend using a configuration management tools like Chef, Ansible,
              Puppet or Salt (in no particular order) to configure your nodes in a cluster.

                We highly recommend against configuring nodes in your cluster using the HTTP API and
                suggest using a configuration management tool for all configurations.
