Want to learn state of the art front end practices in react js

Q. I want write the most sophisticated code as I am not sure if I am using the best practices in the industry like securing pages, API calls, components etc. I use react js. Where can I learn the best coding practices a professional should follow... 2. I have another query as well.. We use next js just for front end and we are not utilising it's full potential like ssr etc. Is it worth using just for front end? People in my company say it provides better route structure but on the contrary.. React feels like a play ground whereas next is limited in provided libraries. What do you have to say.
