# SocketDrano

Process to gracefully drain Phoenix Socket connections at shutdown.

`Plug.Cowboy.Drainer` is able to handle draining of connections as they complete during
a shutdown. Websockets, however, are long-lived connections which may not complete before
timeout periods are reached, especially if they have a heartbeat to keep alive. This library
handles both in a single dep to keep things simple.

This module provides a process that during shutdown will initiate shutdown of open Phoenix
sockets. 

Refer to the [HexDocs](https://hexdocs.pm/socket_drano) for more information and examples.

## Installation

## Disclaimer

There are no tests, so use at your own risk. This was needed for something at work. If it
works for you or you want to contribute nice things like tests, PRs welcomed, just open an
issue for anything major _before_ you waste your valuable time.
