# `WebSockAdapter.Plug`
[🔗](https://github.com/phoenixframework/websock_adapter/blob/main/lib/websock_adapter/plug.ex#L1)

Basic plug to upgrade a connection to `WebSock` connections without a separate plug.

This simplifies basic usage of `WebSockAdapter` in combination with plug accepting
functions like starting a webserver or hooking into routers, where handler
implementation and initial state are static.

For any more advanced cases consider using a custom plug.

## Example

    opts = [
      impl: HandlerModule,
      state: [initial: :state]
    ]

    Bandit.start_link(port: 4000, plug: {WebSockAdapter.Plug, opts})

## Options

- `:impl` - Sets the handler implementation module. Required.
- `:state` - Sets the handlers initial state. Required.

Any further options will be forwarded to `WebSockAdapter.upgrade/4`.

# `call`

# `init`
