Practical - YouTube API

• YouTube API

• Your page has an entry field in which you can type a search term.
• When you click a submit button, the Javascript on your page searches the British Pathé archive on YouTube for videos matching that term.
• You do this using the YouTube API with a JSONP call.
• This returns a function wrapped round data.
• Your page parses the data in order to display a nice preview of the videos.

• You will need to register with YouTube to get an API key.
• The API needs to know "channel id". To find channel id: View Source of channel page and find:
  data-channel-external-id

• To see the structure of the data returned:
  1. Read the YouTube docs.
  2. Type variable name in JS console and click through.
  3. Output complex objects to console.

• Check for empty list: If no videos are returned, display an error message explaining the list is empty.

• Your page should be running at some URL. You should keep this URL secret from other students. And also so as not to expose your API key. (Not a disaster, but just good practice.)
