E-Commerce Frontend: Theme, Data Flow, and UX

Published 4/18/2026

Part 1 on dark mode strategy, RTK Query patterns, and resilient client-side UX.

Theme system first

I prioritized theme architecture early because visual consistency affects every component. A stable token system made dark mode easier to maintain as pages expanded.

Data flow notes

RTK Query helped keep request state predictable and avoided manual loading/error boilerplate.

const { data, isLoading, error } = useGetProductsQuery({ categoryId, page });

Lesson learned

In commerce UI, reliability beats visual complexity. Clear loading states and failure paths improve trust more than decorative interactions.
