I am no longer working on the project that required this set of tools. I am happy to accept pull requests but won't be actively developing new features or fixing any bugs. recorder-js was just slightly modernizing an existing library and the rest of this project is just a simple react component. Feel free to fork, copy and modify this. Hopefully it helps or is at least a good jumping off point for something better!
