I am writing this tutorial to hopefully help others who want to experiment with Today Widgets in React Native. I am not an iOS developer and my work has been mostly trial and error, but I did end up with a working widget which can be modified from javascript, just like a normal React Native component.

A lot of credit goes to rclai. His repo really helped me getting started. I also want to credit dewski, who have provided valuable information on setting up the widget.

If you have any additions or improvements are very welcome to let me know.

Ok, lets get to it.
