Smart WebSocket
// constructor(socketAddress, options = [], autoReconnect = true, debugName = null)
// debugName is used for console logs. If omitted socketAddress will be used instead.
let socket = SmartWebSocket("ws://127.0.0.1:8080", [], true, "sock");
socket.url = "ws://127.0.0.1:8081";
socket.protocols = [];
socket.debugName = "mySock";
// close if connection is open, then re-open connection
// applies changes to socket.url and socket.protocols
socket.reconnect()
// internal WebSocket element.
console.log(socket.socket);
// is socket connection open
if (socket.isReady()) {
// sends
// {"event" : "myEvent", "data" : { "abc" : "def" }}
// to server
// data is stringified using JSON before sending
socket.send("myEvent", { "abc" : "def"});
// sends
// abcdef
// to server. Same as calling socket.send on a regular WebSocket
socket.sendRaw("abcdef");
}
// is called when a JSON of the kind {"event" : "anotherEvent", "data" : {}} is received
socket.on("anotherEvent", (data) => {
console.log(data);
});
// same as calling socket.addEventListener("open") on a regular WebSocket
// same behaviour applies to events "close", "error" and "message"
socket.on("open", (event) => {
console.log(event);
});
// close socket and disable auto-reconnect
socket.close()
