Hello friends, here is my take on a React boilerplate for FiveM, using TypeScript and Lua. The state management is not Redux, but Recoil FYI, which I find way easier to work with, and I hope you will too.
I will try to keep this short, since most of the information you need, is in the github link.
I know there is other boilerplates out there, but this is the way we do it. If you have any issues or questions, let me know 
I will also try to release a boilerplate, only using TypeScript as well, since its AWESOME!
EDIT:
Use this instead.
