node exports return an empty object

Question

In my app.js I exported the function:

var video_sets = [];
...// get the video_sets
console.log(video_sets);
module.exports = {
    requestVideo: function () {
        return video_sets;
    }
};

I tried using console.log(video_sets) to make sure it's not an empty array. When I call this function in another module I get an empty object.

var app = require('./app');
console.log(app.requestVideo());

Answer 1

You can only do :

module.exports.video_sets = video_sets;

No need for extra lines.
