socket.io for react native (sending query problems)

Question

I'm using this library and i can connect without problems.

Usually when I have worked with sockets the code that ever i used is:

socket = io.connect(url, { query: ‘token=’ + token});

and i can see this info reading socket.request._query

Using socket.io for react native i'm trying to send params:

this.socket = new SocketIO('http://localhost:3000', { query: ‘token=’ + token});

but in socket.request._query only can see this log:

{ transport: 'polling', b64: '1' }

In the library some options are mentioned like: connectParams. But i don't know how i can see the info

It's not pretty detailed in the repo, but connectParams is a key/value object, and furthermore the values you sent in it will be appended in the url, as shown here:

    if connectParams != nil {
        for (key, value) in connectParams! {
            let keyEsc   = key.urlEncode()!
            let valueEsc = "\(value)".urlEncode()!

            queryString += "&\(keyEsc)=\(valueEsc)"
        }
    }

So, you should try using connectParams like this(though I'm not sure how you tried it before):

this.socket = new SocketIO('http://localhost:3000', {
  connectParams: {
    myAwesomeQueryStringParam: "someRandomValue"
  }
});
