Current behaviour

When I install socket.io-client on a blank React Native Expo project I have a yellow message with:

Unrecognized WebSocket connection option(s) `agent`, `perMessageDeflate`, `pfx`, `key`, `passphrase`, `cert`, `ca`, `ciphers`, `rejectUnauthorized`. Did you mean to put these under `headers`?

Steps to reproduce (if the current behaviour is a bug)

yarn add socket.io-client

In App.js in the React Native project:

import React from 'react';
import { YellowBox } from 'react-native';
import io from 'socket.io-client';

YellowBox.ignoreWarnings(['Remote debugger']);

import AppContainer from './config/routing';

export default class App extends React.Component {
    constructor(props) {
        super(props);
    }

    componentWillMount() {
        const socket = io('http://10.0.60.26:3000', {
            forceNew: true
        });
        socket.on('connect', () => console.log('Connection'));
    }

    render() {
        return <AppContainer />;
    }
}

For me it worked when I downgraded to 2.1.1 I did: yarn add socket.io-client@2.1.1

At first it didn’t work because I was adding the ^ symbol before the version socket.io-client@^2.1.1 which I believe accepts other minor versions of the package.

const _io = ioClient.connect(socketurl, { forceNode: true }); It’s work
