Running this Node.js server will get the Top 10 Youtube videos in Hong Kong on an hourly basis and store the results in MongoDB. Past results can be accessed through a RESTful API.

Install all dependencies

npm install

Run MongoDB

mongod

In the root directory, create a new file called settings.js, and paste your Google API Key in this format:

module.exports = { key: [API-KEY-HERE] };

Start server with index.js as entry point

npm start

A Cron job is configured in server to retrieve the top 10 YouTube videos in Hong Kong on an hourly basis, at :00 of each hour.

The Video schema has the following fields:

• Time String - identify the time when the record is saved
• Result - an array of YouTube videos, with information including Video ID, Title, Description, Thumbnail, Viewcount

{
	'timeString': String,
	'result': [{
		videoId: String,
		title: String,
		description: String,
		thumbnail: String,
		viewCount: Number
	}]
}

To access database records, sends a GET request to /youtube with a query in this format

q=yyyymmddhh

For example, running the server locally and retriving the record for 7 December 2016 16:00 should look like this

http://localhost:3000/youtube?q=2016120716

If there is a matching record, it returns in JSON format.
