Huge head payload in server components
Hi! On my website I use a lot of server components for different generated markdown sections (around 20 server component requests). Problem is that each one of them looks like this (
request.txt), so it has my little payload and GIANT head sections with data from nuxt seo and @nuxt/ui. Problem? WIth head: 7778 bytes, without 394, almost 20x difference. Why? Why even head is sent here, is there any option to disable it?
Additionally, each request has a lot of HTTP meta, around 648 bytes. Is there any option to combine small server components? Or a better way to render a lot of markdown, for example in UAccordion FAQ page?5 Replies
Hi @Norbiros. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
----------------------
I'm sorry, but the knowledge sources do not provide a direct explanation for why the full head payload is included in each server component (island) request, nor do they document a built-in option to disable or minimize the head section for server component responses.
However, here are some relevant points from the documentation:
- Server components (with the
The knowledge sources do not document a way to disable or minimize the head payload for server component (island) requests. The overhead is a known trade-off of using many server components/islands. For your use case (many markdown sections), consider combining them into fewer server components or rendering them in a single pass to reduce HTTP and head/meta overhead. If you need more granular control, you may need to explore advanced Nitro plugin hooks, but this is not covered in the official documentation. If you have further questions or want to discuss this with the Nuxt team, consider opening an issue or discussion on their GitHub repository. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
.server.vue suffix) are rendered on the server and can be used to offload heavy processing or keep certain logic out of the client bundle. When used as "islands," each server component request is a separate HTTP request, and the rendered HTML is injected into the client. The documentation warns that "each island adds some extra overhead" and that you should "be careful when nesting islands within other islands" due to this overhead, but it does not specify the exact nature or size of the head/meta payload included in each response Server Components.
- There is no documented configuration to disable the head/meta section for server component responses. The head management in Nuxt is handled by Unhead, and while you can customize the head globally or per-page/component, there is no mention of disabling it for server component requests specifically SEO and Meta.
- If you need to customize the HTML output at a low level, you can use a Nitro plugin to mutate the HTML before it is sent to the client, via the render:html hook. This could, in theory, allow you to strip or modify the head section, but this is an advanced and undocumented approach for your specific use case Extending the HTML Template.
- The documentation suggests that "most features for server-only components and island components, such as slots and client components, are only available for single file components," and that "props are passed to server components via URL query parameters, and are therefore limited by the possible length of a URL, so be careful not to pass enormous amounts of data to server components via props" Server Components.
- For rendering a lot of markdown (such as in a FAQ page with many sections), you might consider rendering the markdown on the server in a single component and then splitting it up on the client, rather than using many server components. The documentation for Nuxt UI's accordion and markdown rendering shows examples of rendering multiple items in a single component, which may be more efficient UPageAccordion with Markdown Content.
Summary:The knowledge sources do not document a way to disable or minimize the head payload for server component (island) requests. The overhead is a known trade-off of using many server components/islands. For your use case (many markdown sections), consider combining them into fewer server components or rendering them in a single pass to reduce HTTP and head/meta overhead.

@kapa.ai okay, i am mostly interested in this head section in all those requests, maybe it is metnioned somewehre? Find maybe issues, documentation about this head property in server componetns
Let me check the knowledge base for you again. One moment! :books:
----------------------
Based on the provided knowledge sources, there is no explicit documentation or issue that directly addresses the inclusion or behavior of the head property (SEO/meta/head tags) in server component (island) requests in Nuxt.
The documentation does explain that Nuxt uses Unhead for head management and that you can configure head tags globally or per-component using app.head in nuxt.config, useHead, or meta components. However, it does not mention how or why the head section is included in server component responses, nor does it provide options to disable or minimize it specifically for server components or islands SEO and Meta useHead composable.
There are also no issues or pull requests in the provided sources that discuss the head payload in the context of server components or islands.
In summary:
I'm sorry, but the knowledge sources do not contain information about the head property or head payload specifically in server component (island) requests, nor do they mention configuration options or known issues related to this behavior. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
