Standalone usage requires request/response/domain, but not documented

[uuf6429]

Standalone usage works over request, response and domain, but the documentation does not mention this.

This causes various errors such as with the following code:

var fbapp = new fbsdk.Facebook({
  appId  : 'YOUR APP ID',
  secret : 'YOUR API SECRET'
});

fbapp.getLoginUrl();

Which causes an exception: "No request host available"

From what I gather, it is expected that one sets the aforementioned variables as configuration parameters like the appId and secret.
This has is the cause for a problem in my end; it would require an object per socket connection, whereas one would have been enough (the solution would be to have a different Facebook SDK instance each time).

try this:

app.post('/whatever', function(req, res) {
var fbapp = new fbsdk.Facebook({
appId : 'YOUR APP ID',
secret : 'YOUR API SECRET'
request: req,
response: res
});

});

Sample Code I have:

var fbsdk = require('facebook-sdk');

app.post( '/facebook/register', function ( req, res, next ){

    var facebook = new fbsdk.Facebook({
      appId  : cfg.fb_appId,
      secret : cfg.fb_appSecret,
      request : req,
      response: res
    }); 

    var fbInfo = {};
    if (facebook.getSession() ) {
        fbInfo.uid = facebook.getSession().uid;             // fbuid
        fbInfo.access_token = facebook.getSession().access_token;
        fbInfo.sig = facebook.getSession().sig;
        fbInfo.registration = facebook.getSignedRequest().registration;  // contain all the entries in the FB registration form.
        fbInfo.oauth_token = facebook.getSignedRequest().oauth_token;    // not necessary

    }

    ... do the rest of the stuff, like add user to local DB..etc

});
