Hi, 
our template does not use react hooks by default. It uses mostly class based components to maintain its state. However, if you want to use react hooks then you can do that by reading the docs below if you have experience with react or you can hire a react developer as it is a very big time consuming task to change the complete project code into react hook based code. 

https://reactjs.org/docs/hooks-intro.html

Please let me know if you have any more query. 

Kind regards,
Kamal
