Closing WebSocket correctly (HTML5, Javascript)

Question

I am playing around with HTML5 WebSockets. I was wondering, how do I close the connection gracefully? Like, what happens if user refreshes the page, or just closes the brows

Answer 1

By using close method of web socket, where you can write any function according to requirement.

var connection = new WebSocket('ws://127.0.0.1:1337');
    connection.onclose = () => {
            console.log('Web Socket Connection Closed');
        };
