Nodejs express calling function.

[amir....@nurun.com]

Hi, there is this following code which I'd like to bring the request part out of "app.post", store it in a separate file and call it whenever needed.

I have tried the export method but I was keep getting the undefined for "req" and "res".

app.post('/hook', function (req, res) {
    url = "https://MY_URL",


    // ( request part )
    // I'd like to store following to a separate file
    // and call it from main file whenever needed.


    request({url : url, headers : {"Authorization" : auth}},
    function (error, response, body) {
        parseString(body, function (err, result) {
            try {
                return res.json({
                    "SOME_JSON": "JSON"
                });
            } catch (err) {
                console.error("no request!", err);
            }
        });
    });
    // end request
});

a help on this would be greatly appreciated.
