BASIC USAGE

<script src="../dist/libssh2.js"></script>
<script>
	let libssh2, session, channel;
	const user = 'root', passwd='yourpass';
	ssh2Loader().then((wasm) => {
		libssh2 = wasm;
		libssh2.init(0);
		doconn();
	});

	function doconn() {
		const url = 'ws://websocket_to_ssh2/api_url';
		session = libssh2.createSESSION(new WebSocket(url), (rc, err)=> {
			if(rc === libssh2.ERROR.NONE) {
				session.login(user, passwd, (rc, msg) => {
					if(rc === libssh2.ERROR.NONE) {
						session.CHANNEL((rc, _ch) => {
							if(rc === libssh2.ERROR.NONE) {
								channel = _ch;
								doshell();
							}
						});
					}
				});
			}
		});
	}

	function doshell() {
		channel.onmessage((rc, msg) => {
			console.log('got message', msg);
		});
		channel.shell((rc, msg) => {
			console.log(rc, msg);
			if(rc === libssh2.ERROR.NONE) {
				console.log('got shell ok\r\n');
				// some COMMANDs
				channel.send('cat /proc/version\n');
		});
	}
</script>
