Usage

import { WebSocketClient, WebSocketServer } from 'nativescript-betterwebsockets';  

WebSocketClient:

/** Inside your page component **/

this.client = new WebSocketClient(url);
// Open Event
this.client.on('open', function(handshake){
    console.log('Opened!');
    this.main(); // Do everything else here
});
// Message Event
this.client.on('message', function(message){ 
    console.log('New message: ' + message);
});
// Close Event
this.client.on('close', function(code, reason, remote){
    console.log('Closed!');
});
// Error Event
this.client.on('error', function(ex){
    console.log('Error!');
});
// Connect (Do after setting the events!).
this.client.connect();

// This will be executed after the open event.
main() {
    // To prevent crashes, send messages after the socket is opened.
    this.client.send('Hey!');
    this.client.close(); // Close the client :(
}

Other WebSocketClient methods are avaliable here.

WebSocketServer:

let port = 3000;
this.server  =  new  WebSocketServer(port);
// Start Event (Server Started successfully)
this.server.on('start', () => {
    console.log('Server listening on *:'  +  port);
});
// Open Event (Someone connects)
this.server.on('open', (conn, handshake) => {
    console.log('New Conenction!');
    conn.send('You are connected!'); // Send message to socket
});
// Message Event
this.server.on('message', (conn, message) => {
    console.log('New message: ' + message);
});
// Close event
this.server.on('close', (conn, code, reason, remote) => {
