build(deps): bump @unhead/vue from 2.1.13 to 3.0.0

[dependabot]

Bumps @unhead/vue from 2.1.13 to 3.0.0.

Release notes

Sourced from @​unhead/vue's releases.

v3.0.0

Unhead v3 rebuilds the rendering engine from the ground up. The motivation: streaming SSR. Frameworks like Nuxt, SolidStart, and SvelteKit stream HTML to the browser as data loads, but head tags were still stuck in a request/response model, resolved once and never updated. To fix this properly, we had to make rendering synchronous, pluggable, and side-effect free. The result is a faster, smaller, and more capable head manager.

📣 Highlights

🌊 Streaming SSR

Head tags now update dynamically as suspense boundaries resolve during streaming. As each chunk streams to the browser, new <title>, <meta>, and <link> tags are pushed to a client-side queue and applied to the DOM. No waiting for the full page to load.

// entry-server.ts
import { createStreamableHead } from '@unhead/vue/stream/server'
const { head, wrapStream } = createStreamableHead()
app.use(head)
// wraps the Vue stream, injecting head updates as chunks resolve
return wrapStream(renderToWebStream(app), template)

// entry-client.ts
import { createStreamableHead } from '@unhead/vue/stream/client'
const head = createStreamableHead()
app.use(head)

Under the hood: a queue stub (window.__unhead__) collects head entries as they stream in before the main JS bundle loads. Once the client head instance initializes, it processes the queue and takes over. No entries are ever lost regardless of timing.

Streaming is supported for Vue, React, Solid.js, Svelte, and vanilla TypeScript. See [PR #537](unjs/unhead#537).

🛠️ Unified Vite Plugin + DevTools

A single @unhead/{framework}/vite plugin replaces the old manual composition of @unhead/addons + streaming plugin + framework glue. One import, one call, and you get tree-shaking, useSeoMeta → useHead transform, inline minification, streaming SSR, dev-mode ValidatePlugin auto-injection, and Vite DevTools integration.

// vite.config.ts
import { Unhead } from '@unhead/vue/vite'
import vue from '@vitejs/plugin-vue'
export default defineConfig({
plugins: [vue(), Unhead()],
})

The DevTools panel surfaces live head state during development: every useHead() / useSeoMeta() call with its source file and line number, resolved tags, SEO overview (title, description, canonical, Open Graph), useScript() load status, active plugins, template params, and warnings from the Validate plugin. Source tracing lets you click through from any tag back to the exact line that created it.

Available for Vue, React, Svelte, Solid, and vanilla via @unhead/bundler/vite (the renamed @unhead/addons package; the old name still works with a deprecation warning).

[PierreBrisorgueil]

Superseded by #3948 which bumps both unhead and @unhead/vue to v3.0.0 together (they must share the same major version).

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
