# `PhoenixDatastar.Registry`
[🔗](https://github.com/RicoTrevisan/phoenix_datastar/blob/v0.2.0/lib/registry.ex#L1)

Dynamic process registry for PhoenixDatastar GenServers.

Each live SSE session gets a GenServer process. This module provides helpers
for naming and looking up these processes via Elixir's Registry, keyed by session_id.

## Setup

The Registry must be started in your application supervisor:

    {Registry, keys: :unique, name: PhoenixDatastar.Registry}

# `via`

```elixir
@spec via(String.t()) :: {:via, Registry, {module(), String.t()}}
```

Generate a registry "via tuple" for a given session_id.

Returns a tuple suitable for GenServer's `:name` option to dynamically
register and lookup processes.

## Examples

    iex> PhoenixDatastar.Registry.via("session-abc123")
    {:via, Registry, {PhoenixDatastar.Registry, "session-abc123"}}
