exns (beta)

Interact with Python nanoservices from Elixir.

Usage

• Update your app’s config.exs with your nanoservices

config :exns, nanoservices: [

  [name: :math_service,
   address: "ipc:///tmp/math-service.sock",
   timeout: 5000,
   workers: 10],

  [name: :string_service,
   address: "ipc:///tmp/string-service.sock",
   timeout: 5000,
   workers: 10,
   encoder: "msgpack"]]

• Make calls to a nanoservice

# Successful request
{:ok, result} = Exns.call(:math_service, "add", [1, 2])
IO.puts "1 + 2 = #{result}"

# Optimistic request
3 == Exns.call!(:math_service, "add", [1, 2])

# A request which erred on the python side
{:error, error} = Exns.call(:math_service, "your_non_existing_method")
