Example

`
const {WebSocketServer,WebSocket} = require ("websocket-mockup");

const server = new WebSocketServer ({
host: "example.com"
});

server.on ("request", (request) => {
//Get protocol
const protocol = request.requestedProtocols[0];

//Accept the connection
const connection = request.accept (protocol, request.origin);

console.log ((new Date ()) + ' Connection accepted.');
connection.on ('message', function (message) {
if (message.type === 'utf8')
{
console.log ('Received Message: ' + message.utf8Data);
connection.sendUTF (message.utf8Data);
} else if (message.type === 'binary') {
console.log ('Received Binary Message of ' + message.binaryData.length + ' bytes');
connection.sendBytes (message.binaryData);
}
});
connection.on ('close', function (reasonCode, description) {
console.log ((new Date ()) + ' Peer ' + connection.remoteAddress + ' disconnected.');
});
});

const ws = new WebSocket("wss://example.com");

ws.onopen = (event) => {
console.log("opened");
ws.send("hi!");
};
ws.onclosed = (event) => console.log("closed");
ws.onerror = (event) => console.log(event);
ws.onmessage = (event) => {
console.log("message: "+event.data);
ws.close();
};
