Where can I find source code of courses?

I have subscribed to the redux, and react course.
Anyone knows where can I find the source code of the courses?

For the Redux course the link to the source codes is below the video of the Getting Started section, lecture Setting Up the Development Environment (the red link is for the video - scroll further down if you don’t see the source code link).

The React course has several different source code packages attached to different videos.
