SSR - Hydration text mismatch

[imcm7]

On server it not read color because color is stored in local storage and not cookie

I've got the same issue here

You can try use ClientOnly for components that use theme variable like this

<div class="color-theme-switcher">
  <ClientOnly>
    <SfIcon
      :icon="iconName"
      class="color-theme-switcher__icon"
    />
  
    <span class="color-theme-switcher__text">
      Theme
    </span>
  
    <SfToggleSwitch
      v-model="isDark"
      class="color-theme-switcher__toggler"
    />
  
    <template #placeholder>
      <div class="color-theme-switcher__placeholder" />
    </template>
  </ClientOnly>
</div>

@Kolobok12309 Then on page refresh that content inside ClientOnly will disappear until client render

    </template>
  </ClientOnly>
</div>

@TsotMe Most powerful way is to use cookie and http header for ssr, and if both of them missing, use ClientOnly. Fulfillment without ClientOnly you can try use css( but I don't like css for this cases), or you get flashes between render and mount

It seems cookie storage is merged but this issue is not fixed.
The interesting thing is, when I use <img :src="/img/logo-${colorMode.value}.svg">, src attribute doesn't update after mount.
Because colorMode.value only changes to real value after mount but the attribute doesn't get updated.
I get a lot of mismatch errors.
