From 4ee78bb973d4de3848a9182c0358537c1127b7a2 Mon Sep 17 00:00:00 2001 From: Broque Thomas <26755000+Nezreka@users.noreply.github.com> Date: Thu, 7 May 2026 19:21:19 -0700 Subject: [PATCH] Migrate 7 more discover sections to the shared controller MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Follow-up to the foundation commit. Drops the hand-rolled try/catch + spinner injection + empty-state HTML + error-swallow in seven sections by routing them through `createDiscoverSectionController`. Each section keeps its existing public function name + signature so callers, refresh buttons, and dashboard wiring don't notice the swap. Migrated: - `loadDiscoverReleaseRadar` (Fresh Tape) - `loadDiscoverWeekly` (The Archives) - `loadDecadeBrowser` (Time Machine intro carousel) - `loadGenreBrowser` (Browse by Genre intro carousel) - `loadSeasonalPlaylist` (Seasonal Mix) - `loadYourArtists` - `loadBecauseYouListenTo` Skipped (don't fit the controller's single-fetch / single-render-target shape): - `loadYourAlbums` — paginated grid + filters, updates four separate UI elements (subtitle, filter chips, download button, grid). - `loadSeasonalAlbums` — receives pre-fetched data from `loadSeasonalContent`; no fetch URL to satisfy. Hidden / dead sections (~13 of them — `loadPersonalized*`, `loadDiscoveryShuffle`, `loadFamiliarFavorites`, `loadCache*`) untouched in this pass. Separate audit commit will surface or kill them. Two side-effects worth noting: - `loadDecadeBrowser` and `loadGenreBrowser` migrated for completeness, but neither appears wired into `loadDiscoverPage` or any inline handler. May be dead code — flagged for the audit pass. - `loadSeasonalPlaylist` needs a per-load fetch URL (varies by `currentSeasonKey`); worked around by recreating the controller when the key changes. Cleaner option: extend the controller to accept a `fetchUrl: () => string` callable form. Tracked in the follow-up extension list below. Controller extension candidates surfaced for follow-up: - Callable `fetchUrl` (resolves the seasonal playlist recreate-on-key-change hack) - Explicit `isStale` / `onStale` hook (so Your Artists doesn't fold stale handling into renderItems) - `beforeLoad` / `ensureContentEl` hook (so Because You Listen To can let the controller own the dynamic container creation) - No-fetch `data:` mode (so render-only sections like Seasonal Albums can use the controller too) - `onSuccess(data)` hook (cleaner home for header / subtitle side-effects vs folding them into renderItems) Net: -76 lines in `discover.js` even after adding the per-section render helpers. 2204/2204 full suite green.
