Closes #2531

Context

The user profile page was updating its page query with router.replace while infinite scroll was loading more packages. Nuxt treated that as a navigation and could scroll the window back to the top before the next page was reached.

Description

• Update profile pagination, filter, and sort query parameters with window.history.replaceState, matching the existing search-page pattern.
• Cancel both debounced URL handlers when the page unmounts.
• Make the browser fixture return deterministic paginated user results and add a Playwright regression that crosses page 1 to page 2 while retaining a non-zero scroll position.

Testing

I did not run commands locally because this contribution was made through GitHub APIs without a local checkout. The repository CI runs these exact commands:

• pnpm vp run lint
• pnpm vp run test:types
• pnpm vp test --project unit --coverage --reporter=default --reporter=junit --outputFile=test-report.junit.xml
• pnpm vp run build:test
• pnpm vp run test:browser:prebuilt

The browser regression uses the deterministic npm fixture with ?p=npm; it does not exercise live registry or Algolia data. I could not capture before/after screenshots in the API-only workflow.

📝 Summary

Summary by CodeRabbit

• Bug Fixes
  • Profile pagination now loads additional results correctly, updates the page number in the URL and preserves the current scroll position.
  • Page, filter and sort settings are reflected in the URL without removing other query parameters. Default values are omitted for cleaner URLs.

Walkthrough

Profile pagination now updates the URL with history.replaceState, without using router navigation. Fixture-backed search responses apply pagination parameters. An end-to-end test checks the second-page request, URL update, and scroll position.

Changes

Profile infinite scroll

Layer / File(s)	Summary
Profile URL synchronisation app/pages/~[username]/index.vue	The profile page updates query parameters with history.replaceState and cancels pending URL updates when the component unmounts.
Fixture pagination and end-to-end validation modules/runtime/server/cache.ts, test/fixtures/mock-routes.cjs, test/fixtures/users/scroll-test.json, test/e2e/profile.spec.ts	Fixture-backed responses apply from and size pagination. The 60-package fixture supports an end-to-end test that checks the from=50 request, the page=2 URL, and the scroll position.

Priority: ➖ Normal

Severity of issue fixed: Medium

Merge Risk: 🟡 Moderate · up to ba905

The new test can pass even if pagination still jumps to the top. Check scroll position before another scroll so the fix is reliably validated before merging.

Security Architecture Review

Security architecture risk: 🔵 Low · up to ba905

The change appears confined to public profile display state and test fixtures, with no identified new access to protected data. It can, however, leave the address bar and the page’s route-derived state out of sync.

Retained concerns

• Low · architecture · inferred: Silent URL updates leave Nuxt route.query at its previous value while the profile continues to derive initialPage from it. The immediate scroll behavior is covered, but the URL-to-route state contract is no longer maintained during pagination.

Security review details

Security Blast Radius

• inferred — The changed browser-history write affects the current public profile URL, while the changed server response slicing is confined to fixture interception when that mode is enabled.

Trust Boundaries and Controls

• inferred — No changed query-to-identity or query-to-authorization path was identified: username remains the package lookup identity, and the changed page, filter and sort fields control display and URL state. This conclusion is bounded by the inspected paths and unknown overall Security coverage.

Resilience and Maintainability Implications

• observed — The page cancels both pending debounced URL callbacks on unmount; the infinite-scroll callback emits page changes only when the visible page changes.

Check the URL before each follow-up scroll.

PackageList emits pageChange from scrolling, and the profile handler writes the URL after a 300 ms debounce. The first loop can exit after page=2 appears. After the response wait, the second loop still scrolls to the bottom before checking the URL, so it can hide a scroll reset before the scrollY assertions. Check for page=2 at the start of each iteration.

Suggested fix

     await nextPageResponse
     for (let attempt = 0; attempt < 2; attempt++) {
+      if (new URL(page.url()).searchParams.get('page') === '2') break
       await page.evaluate(() => {
         const scrollingElement = document.scrollingElement ?? document.documentElement
         scrollingElement.scrollTop = scrollingElement.scrollHeight
