Get Video Links (in HD 720p) from CodeSchool

get-video-links-codeschool.js

//[Steps]
//1) Go to your course page => for instance: https://www.codeschool.com/courses/try-elixir/videos
//2) Execute the code below
//3) Check your console
//4) Copy the video links and use them in a download tool you like

//[Notes]
//- You need to be logged in and have access to the videos (some of them are only available for premium users)
//- The output (in your console) is a huge stringified JSON. Use it to download your videos with any tool you like (wget, curl, aria2, etc.)
//- You can make use of some extensions that can inject JS in a page (like 'cjs')

    const [_, json] = content.match(regex);
