Why Bundle Size Matters for Memory

In Cloudflare Workers, every byte of JavaScript syntax parsed into the V8 isolate consumes resident memory. A 1 MB bundle can occupy 10-15 MB of isolate heap just for parsed AST and function prototypes.

Framework Comparison

Frameworks with zero or near-zero client hydration (like Astro) or compiled reactive models (like Svelte and Solid) drastically reduce runtime memory compared to heavy component trees.
