SocketProtocolError: Socket hung up

lautiamkok commented 6 years ago

It does not seem to work when I try to use socketcluster-client & socketcluster-server with Koajs and Nuxtjs. I get this error:

/var/www/html/myproject/node_modules/socketcluster-client/lib/scsocket.js:629
    var err = new SocketProtocolError(SCSocket.errorStatuses[code] || failureMessage, code);
              ^

What does it mean?

I have the same issue here even when trying the Getting started example.

lautiamkok commented 6 years ago

@pedronasser I have got it sorted. Have you?

lautiamkok commented 6 years ago

The reason for this error is because Nuxt is a server side app, while socketcluster-client is to be installed on the client side.

FYI, you can use the client, server-side too. Eg:

const scClient = require('socketcluster-client');
const socket = scClient.connect({hostname: "you.host.name", port: 8008});

although if you do use the client, server-side, i recommend to wrap everything in an on connect event eg:

socket.on('connect', function () {
    console.log('CONNECTED');

    let IssuesChannel = socket.subscribe('Github/Issues');
    IssuesChannel .watch((data) => {
        console.log(data);
    });

});

SocketCluster / socketcluster-client
