NuxtImg inside dynamic components during site generation
What is the best way to include images during site generation for NuxtImg wihtin dynamic components? Problem is that when NuxtImg is in component that during static site generation is not part of the DOM (eg v-if="false") then images are not generated in /_ipx/ folder. When user visits page, hydration completes and dynamic component can be loaded (v-if="true"), but corresponding images are missing in /_ipx/ folder. How to tell NuxtImage to not skip those. There are workarounds like image preload or add invisible NuxtImg to DOM but I am looking for more elegant and clear solution.
Example code:
<div v-if="condition">
<NuxtImg width="80" height="80" :src="..." loading="lazy" placeholder/>
</div>

Hi @johnnyno. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
----------------------
This is an interesting question about using NuxtImg within dynamic components during static site generation. Based on the knowledge sources provided, I can offer some insights and potential solutions.
The core issue you're facing is that images within conditionally rendered components (like those with
v-if="false") are not being generated in the /_ipx/ folder during static site generation. This happens because these components are not part of the initial DOM when the site is generated.
Here are a few approaches you can consider:
1. Prerendering Routes:
If you're using static site generation with ssr: false, you can use the nitro.prerender.routes option to explicitly tell Nuxt to pre-render specific image routes. This approach is mentioned in the Static Images documentation:
2. Adjusting the Image Directory:
Make sure your images are in the correct directory. By default, Nuxt Image looks for images in the public directory. If your images are elsewhere, you might need to adjust the dir option in your nuxt.config.ts file, as mentioned in the configuration documentation:
3. Using the preload Prop:
While you mentioned this as a workaround, it's worth noting that NuxtImg supports a preload prop. This can be a clean way to ensure the image is loaded, even if the component is not initially rendered. As described in the preload documentation:
4. Custom Rendering with placeholder:
Another approach could be to use the placeholder prop along with custom rendering. This way, you can ensure a placeholder is always rendered, even if the main image is not initially visible. The placeholder documentation provides examples:
You can also use more advanced placeholder techniques as described in the documentation.
5. Manual Preloading:
If you know which components and images might be dynamically loaded later, you could use the preloadComponents utility to manually preload them. This is described in the preloadComponents documentation.
While these approaches can help, it's important to note that there isn't a perfect out-of-the-box solution for this specific scenario in the current Nuxt Image documentation. The most robust solution might involve a combination of these techniques, depending on your specific use case and requirements.
Remember to test thoroughly, especially if you're using static site generation, to ensure all your images are properly optimized and available when needed.

Solution with adding routes is dirty as single NuxtImg may generate multiple images in the /_ipx/ and moreeover logic is spread across two places (component itselfs and config).
Using preload is not working
