Vue.js Hydration Demystified
summary
Concrete causes and fixes for Vue hydration problems appear: invalid HTML and aggressive HTML minifiers remove fragment comments and break matching, third party scripts mutate DOM, and functions like Math.random or new Date produce differing server and client values. Solutions include using an HTML validator, transferring server values with useState transfer (unique keys) or moving logic to onMounted, enabling improved diagnostics via the Nuxt hydration module and Vue 3.4 messages, and considering partial or progressive hydration to reduce blocking.
