docs: adjust wording to reduce confusion in lifecycle section #32503
Conversation

|
WalkthroughThe documentation for the Nuxt lifecycle was updated to provide clearer and more detailed explanations of Step 6 and Step 7 in the server-side rendering process. Step 6 was renamed to "Render Page and Components," with expanded details about data fetching and the lack of server-side reactivity. A callout was added to emphasise that Vue's reactivity is paused during SSR. Step 7 was renamed to "Generate HTML Output," with refined descriptions of the HTML generation process and the addition of a tip linking to a related video. Existing warnings and callouts were retained. No code or public API changes were made. ✨ Finishing Touches🧪 Generate Unit Tests

81-84: Clarify lifecycle coverage and tighten wordingThe paragraph is clear but still suggests that no lifecycle hooks run on the server, which is technically inaccurate because
onServerPrefetch(andsetupitself) DO execute during SSR. While you’re touching these lines, you can also tighten the prose.-Nuxt renders the page and its components and fetches any required data with `useFetch` and `useAsyncData` during this step. Since there are no dynamic updates and no DOM operations occur on the server, Vue lifecycle hooks such as `onBeforeMount`, `onMounted`, and subsequent hooks are **NOT** executed during SSR. - -By default, Vue pauses dependency tracking during SSR for better performance. +Nuxt renders the page, its components, and fetches any required data with `useFetch` or `useAsyncData` during this step. Because no dynamic updates or DOM operations run on the server, client-only lifecycle hooks such as `onBeforeMount`, `onMounted`, and later hooks are **NOT** executed during SSR. (Server-specific hooks like `onServerPrefetch` still run.) + +By default, Vue temporarily pauses dependency tracking during SSR for better performance.
85-87: Rephrase call-out for stronger accuracyThe current sentence is correct but a tad vague. Explicitly mentioning watchers/computed clarifies what “no reactivity” means.
-There is no reactivity on the server side because Vue SSR renders the app top-down as static HTML, making it impossible to go back and modify content that has already been rendered. +Vue’s effect system is disabled on the server: SSR renders the app top-down as static HTML, so watchers, computed setters, or any reactive updates cannot run after the initial render.
93-95: Addrel="noopener"for safer external linkOpening links in a new tab without
rel="noopener"allows the new page to accesswindow.opener. The docs elsewhere already use this pattern.-::tip{icon="i-lucide-video" to="https://youtu.be/dZSNW07sO-A" target="_blank"} +::tip{icon="i-lucide-video" to="https://youtu.be/dZSNW07sO-A" target="_blank" rel="noopener"}
99-100: Polish wording of Step 7 explanationMinor verb-tense tweaks and a small terminology adjustment improve flow and precision.
-After all required data is fetched and the components are rendered, Nuxt combines the rendered components with settings from `unhead` to generate a complete HTML document. This HTML, along with the associated data, is then sent back to the client to complete the SSR process. +After all required data has been fetched and the components have been rendered, Nuxt merges the output with any `unhead` metadata to produce a complete HTML document. The document and its serialised state are then sent to the client, completing the SSR process.

Timestamp: 2024-12-12T12:36:34.871Z
Learning: In `packages/nuxt/src/app/components/nuxt-root.vue`, when optimizing bundle size by conditionally importing components based on route metadata, prefer using inline conditional imports like:
```js
const IsolatedPage = route?.meta?.isolate ? defineAsyncComponent(() => import('#build/isolated-page.mjs')) : null
```
instead of wrapping the import in a computed property or importing the component unconditionally.
