Put here in env file const API_BASE_URL = "apiurl"; and UI has some contrast issues in dark mode. Code style is looking okay but you have a lot components and small parts at this scale. try to make it more simple to work with

@Dutch Any advice on how the code is written as far as scalability, performance and reusability?

at once i wrote two code side by side, one was trash other was performant. for end user there was no difference, for developer there was not much difference

so personally i dont believe a thing like clean code and optimization

as long as it works without errors and reacts fast, no matter how you write it
