Vue.js Hydration Demystified

on YouTube ↗25m

" summary

Explains why hydration fails (invalid HTML, optimizer scripts stripping Vue comments, differing server/client state from Math.random, Date, localStorage or import.meta.client) and how to fix and debug it: enable Vue 3.4 hydration mismatch details in staging, run an HTML validator, use useState to serialize server values, delay client-only initialization into onMounted, and log mismatches. Covers partial/island hydration, Nuxt server components as server-rendered reactive islands, lazy hydration with replay-on-click, and upcoming useId and mismatch hooks.
