Release v0.11.0

Release with support for NATS v2 auth features

Added

• Support for user credentials that contain a JWT/NKEY to auth against NATS v2 servers

require 'nats/client'

NATS.start("tls://connect.ngs.global", user_credentials: "/path/to/creds") do |nc|
  nc.subscribe("hello") do |msg|
    puts "[Received] #{msg}"
  end
  nc.publish('hello', 'world')
end

• Support to authenticate against NATS v2 servers that use NKEYS

require 'nats/client'

NATS.start("tls://connect.ngs.global", nkeys_seed: "path/to/seed.txt") do |nc|
  nc.subscribe("hello") do |msg|
    puts "[Received] #{msg}"
  end
  nc.publish('hello', 'world')
end

• Added --creds option to nats-pub, nats-sub, nats-queue tools

Changed

• Internal changes to process initial INFO message from the server

Fixed

• Fixed being able to use 'tls' as the scheme when connecting with a single URL

  NATS.connect("tls://demo.nats.io:4443")

Release v0.10.0

Added

• Support for drain mode (#157)

  This feature allows clients to gracefully disconect, letting the subscribers
  handle any inflight messages that may have been sent by the server already.

  NATS.start(drain_timeout: 1) do |nc|
    NATS.subscribe('foo', queue: "workers") do |msg, reply, sub|
      nc.publish(reply, "ACK:#{msg}")
    end
  
    NATS.subscribe('bar', queue: "workers") do |msg, reply, sub|
      nc.publish(reply, "ACK:#{msg}")
    end
  
    NATS.subscribe('quux', queue: "workers") do |msg, reply, sub|
      nc.publish(reply, "ACK:#{msg}")
    end
  
    EM.add_timer(2) do
      next if NATS.draining?
  
      # Drain gracefully closes the connection.
      NATS.drain do
        puts "Done draining. Connection is closed."
      end
    end
  end

• Support for no_echo mode (#155)

  When connected to a NATS Server v1.2.0 or above, a client can now opt to avoid
  receiving messages that it itself has published.

  NATS.connect(no_echo: true)

Improved

• NATS.connect API is now more similar to how it works in the Go client (#156):

  # Assume 'nats://' scheme
  NATS.connect("demo.nats.io:4222")
  
  # Complete with scheme a la Go client classic usage.
  NATS.connect("nats://demo.nats.io:4222")
  
  # Use default 4222 port.
  NATS.connect("demo.nats.io")
  
  # Explicit cluster list still supported
  NATS.connect(servers: ["nats://demo.nats.io:4222"])

Fixed

• Client now supports token based authorization

  NATS.connect(token: "deadbeef")
  
  NATS.connect(uri: "nats://[email protected]:4222")
  
  NATS.connect("nats://[email protected]:4222")
