Building an interactive tarot card component in React: flip animations, state machines, and 78 lazy-loaded images

Short summary

Tutorial on building an interactive tarot card component in React: implements a state machine pattern to manage deck states and prevent double-taps during animations. Uses CSS 3D transforms with perspective on the parent container for smooth card flips. Demonstrates lazy-loading by preloading only the card back and first 5 cards while converting all 78 card images to WebP, reducing total payload from 7MB to 2.5MB.

• •State machine pattern (idle/shuffling/drawing/revealed) prevents double-taps during animations better than boolean flags
• •CSS perspective must be on parent container, not rotating element; Safari requires -webkit-backface-visibility
• •Smart image optimization: preload card back + first 5 cards, lazy-load rest on draw; WebP reduces 78 cards from 7MB to 2.5MB
