README

discovery-node

This library programmatically finds endpoints for dependencies. Similar to discovery-go and discovery-python.

See Service Discovery for more details.

API

• disc = discovery(, )
• disc.proto() - returns the service protocol
• disc.host() - returns the hostname or ip
• disc.port() - returns the port
• disc.host_port() - returns (:)
• disc.proto_host() - returns (://)
• disc.url() - returns the url (://:)

Install and import

install --save clever-discovery

offee
overy = require "clever-discovery"

Examples

_gearman = discovery("gearman-admin", "http")
gearman_url = disc_gearman.url() catch err then cb(err)

_systemic = discovery("systemic", "thrift")
systemic_host = disc_systemic.host() catch err then cb(err)
systemic_port = disc_systemic.port() catch err then cb(err)

To see what interfaces a Clever service exposes, check its launch yaml. You should see one or more exposes listed, and the name of the expose is used as the interface value in the discovery client.
