Edge caching and HTML5 game assets without heavy payloads

Edge caching is about moving bytes closer to players and serving immutable files with long TTLs while keeping HTML entrypoints flexible. For AI mini games, the win is predictable cold starts: fewer round trips, smaller bundles, and less jank when a feed preloads the next card.

Immutable filenames, short HTML

Fingerprint JS and CSS assets so caches can stay hot for months. Keep index.html or your shell document short and cache-busted when logic changes. This pattern pairs with Text-first assets and performance budgets.

Workers as a routing layer, not a second game engine

Workers can rewrite paths, stitch auth, or add security headers—but the game still runs client-side. Do not hide gameplay complexity behind edge logic unless you need it. For a primer, read Cloudflare Workers and edge hosting.

Image discipline still matters

Even with great caching, oversized hero art hurts LCP inside embedded webviews. Prefer SVG shapes, small PNGs, or responsive sources with explicit dimensions to reduce layout shift.

Connect caching to discovery

Feeds prefetch aggressively; unstable cache keys cause churn and wasted bandwidth. If you are optimizing for portrait surfaces, revisit Portrait feed discovery beats a static AI game gallery. For neutral vendor evaluation, see Compare with Astrocade.
