Hello, I am new to Node.js and have been researching about its capabilities of obtaining real-time data. I came across Bucky's video playlist for Node.js for beginners and I am starting to get the hang of it but my question is:

How can I use Node.js to obtain data such as finding most shared video or most searched word within a social media websites? I see a lot of tutorials on building real-time applications or setting up real-time chat but having hard time figuring out how to apply it to find(obtain) data from other popular social media.

For beginners to Node.js and MEAN.js stack in general, is there any knowledgeable resources that can help me get my answer to the question? Or a general direction on how to tackle the problem?
