How to Build a Movie Recommendation UI in React
A movie recommendation UI is the core of a Netflix clone. Here is how to build it step by step.
The Pattern
Fetch movie lists from an API, group them by category, render them as horizontal carousels, and let users click into a detail modal. That is the recommendation UI.
Fetching Lists
In useEffect, fetch categorized movie lists from TMDB: trending, popular, top-rated, and so on. Store each list in state, handle loading and errors, and render each when ready.
The Carousel Component
Build a MovieList component that takes a title and an array of movies, and renders a horizontal scrollable row of MovieCard components. Add scroll buttons for desktop and allow native scroll on mobile.
The Movie Card
Each card shows a poster and, on hover, the title and a play button. Use CSS for the hover overlay and an accessible button for opening the detail modal.
The Detail Modal
When a user clicks a card, open a modal with the movie's details: backdrop, title, overview, cast, and a trailer if available. Handle backdrop click and escape to close.
Empty and Error States
Handle the case where a list is empty or fails to load. Show a fallback message instead of a blank row, so the UI never looks broken.
Performance
Virtualize or lazy-load posters to keep the page fast when there are many movies. Stable keys are essential for the carousels to update correctly.
The Takeaway
A movie recommendation UI is fetching categorized lists, rendering them as carousels of cards, opening a detail modal on click, and handling empty and error states. Performance and stable keys keep it smooth.
Fetch categorized movie lists from an API, group them by category, render each as a horizontal carousel of MovieCard components, and open a detail modal when a user clicks a card. Handle loading, empty, and error states throughout.

Show a fallback message instead of a blank row, so the UI never looks broken. If a list fails to load, show an error state with a retry. Always handle empty, loading, and error for every fetch.
Virtualize or lazy-load posters so the page does not try to load hundreds of images at once. Use stable unique keys for carousel items so React updates them efficiently, and memoize where measured necessary.
