Feathers: how does real-time work?

[sarkistlt]

I mean it works as in Meteor just pulling requests each 'n'ms trough Socket, or like in graphQL through subscription?

Because the first one is not the best solution for big projects.

@sarkistlt, it works however you setup the transports for whichever provider plugin you use. Both Socket.io and Primus support multiple transports.

See http://socket.io/blog/introducing-socket-io-1-0/#new-engine or https://github.com/primus/primus#supported-real-time-frameworks

So, technically, it can be either. But generally, just as you mentioned, for performance reasons you would use subscription. Here's an example of how to lock in the socket.io provider to only allow subscriptions over websockets:

const io = require('socket.io-client/socket.io');
const socket = io('http://api.feathersjs.com', { 
  transports: ['websocket'] 
});
const app = feathers()
  .configure(feathers.hooks())
  .configure(socketio(socket));

Sorry. Didn't mean to close this. Please reopen if I didn't answer your question.

Thanks for quick answer, that sounds great!

One more thing. When I try to const io = require('socket.io-client/socket.io');

I get following error:

var isAndroid = navigator.userAgent.match(/Android/i);
                    ^

ReferenceError: navigator is not defined
    at Object.<anonymous> (/Users/Sarkis/Documents/_projects/Coda/hum-app_v2/node_modules/socket.io-client/socket.io.js:4796:18)
...

[marshallswain]

If you're working in node, just do const io = require('socket.io-client');

[marshallswain]

navigator is a global browser object. Not sure why they didn't make it const io = require('socket.io-client/browser'); for the browser

works now, thanks again)

BTW, the doc server responded with a status of 502

for example this link: https://docs.feathersjs.com/getting-started/scaffolding.html

Yeah GitBooks is down, but you can use the https://github.com/feathersjs/feathers-docs repo.
