ReactPHP blocking process in wordpress plugin

Question

i am trying to make a websocket server in my wordpress plugin.

when i try to access the site it loads alot of time and outputs this iis error:

The FastCGI process exceeded configured request timeout

websocket server code:

$loop = React\EventLoop\Factory::create();
$socket = new React\Socket\Server('127.0.0.1:9000', $loop);

$socket->on('connection', function (ConnectionInterface $conn) {
    $conn->write("Hello " . $conn->getRemoteAddress() . "!\n");

    $conn->on('data', function ($data) use ($conn) {
        $conn->close();
    });
});

$loop->run();

when i remove this code ^ it load fast and no error.

versions:

PHP: 7.2
ReactPHP: ^1.0 
Wordpress: 4.9.2

run it from cli, your not meant to init it from the browser. — Lawrence Cherone, Sep 04 '18 at 16:32
@LawrenceCherone or everyone - is there a way to run it from wordpress? — Neriya Rosner, Sep 04 '18 at 17:01
its possible but you would need to track whether an instance is already running, then you just need to fire off an ajax request to start it, then close the connection, and then hopefully not open the client socket connection till its started.. much more hassle then simply running from cli. — Lawrence Cherone, Sep 04 '18 at 17:05

Hey ReactPHP core maintainer here. Running any socket server including a websocket server is intended to run from the CLI or using supervisor/systemd. My suggestion would be to create such a special cli command in your plugin that you can call to start it. Doing funky magic with XHR requests is very error prone and not very stable. Alternatively if you absolutely cannot run cli commands is a service like pusher

For websockets my go to resource is Ratchet: https://github.com/ratchetphp/Ratchet – WyriHaximus Sep 04 '18 at 17:27
is it possible to forward all requests to another remote websocket server? – Neriya Rosner Sep 04 '18 at 17:41
You can in fact connect to any websocket server that allows you to connect to it. For exampole you can connect from lightx.net to wyrihaximus.net if my server allows it through headers and authentication. – WyriHaximus Sep 04 '18 at 17:55
Connect to `wss://www.wyrihaximus.net/` from the browser side :P – WyriHaximus Sep 04 '18 at 18:13
is it possible to set a custom events in RatchetPHP server? – Neriya Rosner Sep 05 '18 at 13:20
Ratchet hands you a low level API to work with, you have to build your own communication protocol on top of that. You can also use the buildin support for WAMPv1 which gives you RPC and PubSub. Alternatively you can use Thruway for WAMPv2 but that is a whole different beast. – WyriHaximus Sep 05 '18 at 15:04
