Hi @dmarr. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Hydration mismatches with icons like those from lucide-vue-next are a common issue in Nuxt applications. These mismatches occur when the server-rendered HTML doesn't match what the client-side JavaScript tries to render during hydration. Based on the knowledge sources, there are several potential causes for icon-related hydration mismatches: 1. Class order differences: The server and client might render classes in different orders. For example, in one case the error showed: 
   - rendered on server: class="dropdown nav-item me-4 me-xl-5 position-relative"
   - expected on client: class="nav-item me-4 me-xl-5 position-relative dropdown active"
   
   - rendered on server: class="dropdown nav-item me-4 me-xl-5 position-relative"
   - expected on client: class="nav-item me-4 me-xl-5 position-relative dropdown active"
Stack Overflow Post 2. Modifying props or data: If you're modifying data that affects icon rendering during component setup, this can cause hydration issues. For example, using methods like shift() on arrays can cause mismatches because the data is different between server and client renders Stack Overflow Post. 3. Client-side only state changes: If you're changing icon states immediately after mounting (in onMounted hooks), this can cause hydration mismatches because the server-rendered version won't include these changes Github Issue. 4. PWA integration: Adding PWA functionality with packages like @vite-pwa/nuxt can sometimes trigger hydration issues with conditional class rendering Stack Overflow Post. To fix these issues, you could try: 1. Make a local copy of data before modifying it: const localData = [...originalData] 2. Delay state changes that affect icons until after hydration is complete: 
   onMounted(() => {
     nextTick(() => {
       // Change icon state here
     })
   })
   
   onMounted(() => {
     nextTick(() => {
       // Change icon state here
     })
   })
3. If using .server and .client components with icons, ensure they render the same initial output to avoid hydration mismatches. 4. Consider using <ClientOnly> wrapper around problematic icon components if the mismatch can't be resolved otherwise. If you're still experiencing issues, you might need to provide more specific details about how you're implementing the lucide icons in your Nuxt application. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
