return value from callback in node.js and mongoose
You need a callback function since this is an async request:
function authenticate(accesskey, callback) { var auth = null; userModel.findOne({'uid': accesskey}, function(err, user) { console.log("TRY AUTHENTICATE"); if (err) { console.error("Can't Find.!! Error"); } //None Found if (user === null) { console.error("ACCESS ERROR : %s Doesn't Exist", accesskey); auth = false; } else { console.log(user); auth = true; } callback(auth); });}And call this function like :
authenticate("key", function (authResult) { //do whatever});
You can also try with promises.
function authenticate( accesskey ) { var promise = someModel.findOne({'uid': accesskey}).exec();}routeHandler( req, reply ) { authenticate(req.params.accesskey) .then(function (auth) { if(auth) { //"primary code" } else { //fallback } }) .catch(console.error); }
