…brary (#658)

Created a new Slider on the Discover page with links to the full local library view.

Description

I created a new 'My Media Library' Slider at the bottom of the Discover page. This lists 20 of your local media in the standard slider form, and if more than 20 media is found in your library, a 'See More' card is display.

You can also go to the full page My Media Library using the links beside the heading of the Slider.

My Media Library is all your local media, movies and shows with status|status4k of available, and partiallyavailable.

Allows users to quickly see the contents of their (Partially)|Available library.

How Has This Been Tested?

Tested on my local machine using my Jellyfin media library, containing a partially available series and available movies, totalling > 20.

Add Jellyfin library.
Load Discover page, view new Slider.
Click link to library in header.
Scroll slider all the way to the right, click 'See More'

Load '/discover/library' observer full page view of library, available and partiallyavailable.

Manual tests for local (containerized server) Jellyfin library.
Added cypress test for basic navigation of new components.
All testing done with build running locally on my Macbook using Chrome.

I tried to introduce a minimal footprint of these changes, avoiding as many touchpoints in existing codebase as possible.

I heavily relied on AI for the following:

  • Understand modern open source contribution hygiene and best practices.
  • Grok current app architecture and TMDB integration.
  • Evaluate my design and implementation ideas.
  • Review my code, provide feedback from a sw engineering perspective.
  • Review changes for a maintainer PR perspective, assess missing things, etc.

📝 Walkthrough

Walkthrough

This PR introduces an "Available Media" feature to the discover page, enabling users to view media currently available on their server. The changes include a new enum member and slider configuration, new React components for displaying available media with infinite scrolling, a dedicated library page, frontend integration across discover components, translation strings, and E2E test coverage.

Changes

Cohort / File(s) Summary
Backend Constants & Enum
server/constants/discover.ts
Added MY_MEDIA_LIBRARY enum member to DiscoverSliderType and configured default slider entry with enabled state and order 12.
Backend Routes
server/routes/discover.ts
Standardized paging behavior by introducing local page variable with default value of 1, replacing direct Number(query.page) calls in TMDB discovery endpoints.
Available Media Components
src/components/Discover/AvailableMedia/index.tsx, src/components/Discover/AvailableMediaSlider/index.tsx
Added two new React components: AvailableMedia implements infinite scrolling with SWR's useSWRInfinite for paginated media fetching; AvailableMediaSlider renders a slider preview with link to full library page.
Discover Integration
src/components/Discover/index.tsx, src/components/Discover/DiscoverSliderEdit/index.tsx
Integrated AvailableMediaSlider component rendering and added case handler for MY_MEDIA_LIBRARY slider type in both display and edit modes.
UI Constants & Translations
src/components/Discover/constants.ts, src/i18n/locale/en.json
Added availableMedia translation key to slider titles with value "Available Media".
Pages & Routing
src/pages/discover/library.tsx
Created new Next.js page rendering the AvailableMedia component at /discover/library route.
E2E Testing
cypress/e2e/discover.cy.ts
Added test navigating from Available Media slider header to library page, validating URL and page header.

🐰 A library of wonders, filtered clear,
Available media, brought near and dear,
Scroll through the server's finest display,
Clean up collections in the easiest way!

215-224: Add API interception for test consistency and stability.

The MyMediaLibrarySlider component fetches data from /api/v1/media?filter=allavailable&take=20&sort=mediaAdded using useSWR on component mount. This test should intercept that API call before visiting the page, consistent with other tests in this file (trending, popular movies, upcoming movies, etc.). Relying solely on the 15s timeout can lead to flakiness.

♻️ Suggested improvement
   it('navigates from My Media Library slider to the library page', () => {
+    cy.intercept('/api/v1/media?filter=allavailable*').as('getLibraryMedia');
     cy.visit('/');
+    cy.wait('@getLibraryMedia');

     cy.contains('.slider-header .slider-title', 'My Media Library', {
       timeout: 15000,
     }).click();

45-50: Consider memoizing the scroll callback.

The inline arrow function () => setSize(size + 1) creates a new function reference on each render. Depending on how useVerticalScroll handles its callback dependency, this could potentially cause unnecessary effect re-runs. Wrapping it in useCallback would prevent this.

+import { useCallback } from 'react';

   const intl = useIntl();

56-62: Consider more specific error handling.

The generic statusCode={500} error may not accurately represent all failure modes (e.g., network errors, 404s, rate limiting). If the API provides error details, consider passing them through for more informative error pages.

However, this is consistent with common patterns in similar components, so acceptable as-is.

13-16: Consider sharing the media-library query config.

This endpoint shape is now duplicated here and in src/components/Discover/MyMediaLibrary/index.tsx. Pulling the shared filter/sort/page-size bits into a small helper or constant would make it harder for the slider and full page to drift later.
