# Hydrax
Shared functionality for working with PIDs across a distributed cluster. Acts as a wrapper
around [Horde](https://hex.pm/packages/horde), providing a few convenience functions such as helpers for working with two-element registry keys.

## Installation
The package can be installed by adding `hydrax` to your list of dependencies in `mix.exs`:
```elixir
def deps do
[
{:hydrax, "~> 0.3"},
]
end
```
Then add either the Registry, Supervisor, or both to your application tree:
``` elixir
defmodule Application do
@moduledoc false
use Application
@impl true
def start(_type, _args) do
children = [
Hydrax.Registry,
Hydrax.Supervisor,
# other children
]
opts = [strategy: :one_for_one, name: Application]
Supervisor.start_link(children, opts)
end
end
```
The Registry and Supervisor are thin wrappers around Horde.Registry and Horde.DynamicSupervisor. The [Horde documentation](https://hexdocs.pm/horde/readme.html) is the best place to learn how to use these.
