Current behaviour
I can't connect via socket io to my server, it times out.
Steps to reproduce (if the current behaviour is a bug)
In react-native:
import io from 'socket.io-client';
const BACKEND = 'my socketio server url'
const sock = io(BACKEND, { transports: ['websocket'], forceNew: true });
sock.on('connected', () => {
debugger;
})The debug logs look like:
socket.io-client:url parse <my url> +0ms
browser.js:133 socket.io-client ignoring socket cache for <my url> +0ms
browser.js:133 socket.io-client:manager readyState closed +0ms
browser.js:133 socket.io-client:manager opening <my url> +1ms
browser.js:133 engine.io-client:socket creating transport "websocket" +0ms
browser.js:133 engine.io-client:socket setting transport websocket +3ms

socket.io-client:manager connect attempt timed out after 20000 +20s
browser.js:133 engine.io-client:socket socket close with reason: "forced close" +20s
browser.js:133 engine.io-client:socket socket closing - telling transport to close +2ms
browser.js:133 socket.io-client:manager connect_error +3ms
browser.js:133 socket.io-client:manager cleanup +1ms
browser.js:133 socket.io-client:manager will wait 899ms before reconnect attempt +1ms
browser.js:133 socket.io-client:manager attempting reconnect +912ms
Note: the best way (and by that we mean the only way) to get a quick answer is to provide a failing test case by forking the following fiddle.
Expected behaviour
I expect to be able to connect to my socketio server, the same way I am able to in a web browser.
Setup
- OS: iOS iPhone 10 simulator
- browser: React-native
- socket.io version: 2.1.1
