Resumability
Qwik-framework-koncept: server serializerar entire app-state till HTML, client resume:r execution från där server lämnade utan re-executing setup-code. Zero hydration. Miško Hevery (creator av Angular), 2022.
Skiljs från SSR + hydration: traditional approach kör all setup-code igen på client (event-listeners attached, state initialized) → "hydration tax" tunga. Resumability: state + event-handlers serialiseras i HTML attributes (on:click), JS lazy-loaded per interaction only. Result: time-to-interactive snabbare än React/Vue oavsett app-storlek. Trade-off: ovan mental-model, smaller community än React, JS-fragmentation (många små chunks vs one bundle). Adoption-still-niche 2024 men technical-impressive.
