| //[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') |
