Create Next App - Unresolved

Might have been a node.js install issue but NX was able to create Next apps without problems.

Need to check if now resolved.

Eth-Hooks with Nextjs

SyntaxError: Cannot use import statement outside a module

TODO: create a ticket in eth-hooks


Copied code directly into an NX lib.

Primarily wanted to understand the architecture and dependenices of Eth-hooks and Eth-Components and work with React/Nextjs not vite.
