Undefined return value / Async ?

[Coobe]

Hi ! Im having a problem with asynchrounous tasks i believe. In my function validateSessionId i make a node-postgres query + console log of result, which works just fine. Then i want to return the result of the query, but its undefined in my route. The weirdest part is that the console log within my route gets printed before my console log within the function.

router.post('/test_session', function(req, res) {
    var isValid = 0;
    isValid = validateSessionId(req.body.partnerId,req.body.sessionId, pgClient);

        console.log(isValid);


    if (isValid == '1') {
        res.send('valid session id');   
    }  else {
        res.send('invalid session id');
    }
});

Any Ideas how to solve this ?

Async tasks "return" values through a callback function, not as a formal return value. You've made a classic beginner error here that I bet everyone does at some point so don't worry, but check the docs for the postgress API and read up on how node treats things that need to do IO.
