2.0.0 RC1

This library has been refactored to use the new amphp/websocket library containing components that can be shared between server and clients.

Note: This is a pre-release, there might be breaking changes in the final stable version.

Websocket now contains only two abstract methods that must be implemented:

• onHandshake(): This method acts as before, being invoked when a WebSocket connection attempt is made. The application may alter the given Response to deny the connection attempt or set application-specific headers.
• onConnect(): This method is invoked upon a successful WebSocket connection. This method should use a loop to receive messages from the WebSocket connection.

protected function onConnect(Client $client, Request $request, Response $response): Promise
{
    return Amp\call(function () use ($client) {
        while ($message = yield $client->receive()) {
            $payload = yield $message->buffer();
            yield $client->send('Message of length ' . \strlen($payload) . 'received');
        }
    });
}

WebSocket clients are now represented by a Client object. This object contains several methods for getting information about the client and for sending messages to a single client.
