It handles loading history data (via a preferred feed engine or a service fallback), formatting it chronologically, displaying moderation states for videos, and allowing users to interact with history items (play, view channel, or remove). + +It fits into the application as a view-layer controller. It retrieves application state and services via `getApplication()` and relies heavily on `watchHistoryService` for data and NIP-07/NIP-46 signers (via `nostrClientFacade`) to identify the user. + +## Public Surface + +### `buildHistoryCard({ item, video, profile, variant })` +Creates a DOM article element representing a single watch history entry. +- **Parameters:** + - `item` (Object): The history item metadata (contains `pointerKey`, `watchedAt`, etc.). + - `video` (Object): The associated video object. + - `profile` (Object): The creator's profile object. + - `variant` (String): UI variant (e.g., "compact"). +- **Returns:** `HTMLElement` (an `
` tag). +- **Side effects:** Registers the created card in a local `historyCardRegistry` to manage moderation states dynamically. + +### `createWatchHistoryRenderer(config = {})` +Factory function that creates a stateful renderer object to manage the history grid. +- **Parameters:** + - `config` (Object): Overrides for DOM selectors, fetch strategies, and batch sizes. +- **Returns:** An object with lifecycle methods (`init`, `ensureInitialLoad`, `refresh`, `loadMore`, `destroy`) and event handlers (`handleRemove`). +- **Side effects:** Attaches global event listeners for moderation updates (`video:moderation-override`, `video:moderation-block`), DOM event listeners for clicks on the grid, and Intersection Observers for infinite scrolling. + +### `initHistoryView()` +Entry point intended to be called when the watch history page/view is initialized. +- **Returns:** `Promise` +- **Side effects:** Attaches an info popover to `#historyInfoTrigger` and calls `init()` on the default `watchHistoryRenderer`. + +## Main Execution Paths + +1. **Initialization (`initHistoryView` -> `renderer.init`)** + - Resolves DOM elements via selectors. + - Attaches event listeners (click handlers for actions, intersection observer for load more). + - Subscribes to `fingerprint` updates from `watchHistoryService` and moderation events from `document`. + - Checks feature flags (sync enabled, local only) to update the feature banner. + - Triggers `refresh(force: true)` to fetch data. + +2. **Fetching Data (`loadHistory`)** + - Calls `fetchHistory` (which attempts the `watch-history` feed engine first, falling back to `watchHistoryService`). + - Normalizes the retrieved items (`normalizeHistoryItems`), grouping and sorting by `watchedAt`. + - Computes a `fingerprint` string to detect changes. + +3. **Rendering Data (`renderInitial` -> `renderNextBatch`)** + - Clears the existing grid. + - Slices the normalized items based on `batchSize`. + - Hydrates the batch (applies moderation decorators). + - Groups items by day (Today, Yesterday, Date) and appends `buildHistoryCard` results to the DOM. + +4. **User Interactions (Grid Click Handler)** + - Catches click events bubbling up from the grid. + - Dispatches based on `data-history-action`: + - `"play"`: Calls `app.playVideoWithFallback()`. + - `"channel"`: Calls `app.goToProfile()`. + - `"remove"`: Calls `renderer.handleRemove()`, which removes the DOM node, updates the service, and optionally refreshes the view. + +## Assumptions & Invariants +- Assumes the presence of a global application context accessible via `getApplication()`. +- Relies on DOM structure matching hardcoded selectors (e.g., `#watchHistoryGrid`, `#watchHistoryLoading`). +- Assumes `watchHistoryService` exposes `loadLatest`, `snapshot`, `subscribe`, and capability flags (`isEnabled`, `isLocalOnly`). +- Invariant: A card's moderation state is managed dynamically via `historyCardRegistry`; cards must be registered upon creation and cleaned up upon removal. + +## Edge Cases & Error Paths +- **Feed Engine Failure:** If the primary feed engine fails or isn't registered, it gracefully falls back to a locally instantiated engine or directly to the `watchHistoryService`. +- **Empty/Disabled States:** Handles scenarios where history is empty or unsupported (e.g., guest users) by swapping visibility of grid, loading, and empty state containers. +- **Moderation Overrides:** Handles moderation overrides asynchronously. If an override fails, it resets the loading state of the override button and logs the error. + +## Performance & Concurrency Considerations +- Infinite scrolling is implemented via `IntersectionObserver` to lazily render DOM elements in batches (`WATCH_HISTORY_BATCH_SIZE`). +- Uses `DocumentFragment` to batch DOM insertions during rendering. +- Prevents redundant renders by comparing the computed `fingerprint` of the item list before committing changes. + +## When to Change +- Consider refactoring if the hardcoded DOM selectors become brittle during UI component migrations. +- Extract the complex moderation badge generation (`createHistoryCardBadge`, `applyHistoryCardModeration`) if moderation logic needs to be shared across other views (like feeds or search). + +## Why it works this way +- The factory pattern (`createWatchHistoryRenderer`) allows the same logic to power the main page view and potentially smaller embedded views (like a modal variant) by passing different config selectors. +- Keeping a local `historyCardRegistry` prevents having to do expensive DOM queries to find and update video cards when moderation events (like blocking a user globally) occur. \ No newline at end of file diff --git a/js/historyView.js b/js/historyView.js index 33f27d48..2b31b5e2 100644 --- a/js/historyView.js +++ b/js/historyView.js @@ -1160,6 +1160,16 @@ function refreshRegisteredHistoryCards(video, context, pointerKeys = null) { }); } +/** + * Creates a DOM article element representing a single watch history entry. + * + * @param {Object} options + * @param {Object} options.item - The history item metadata (contains pointerKey, watchedAt, etc.). + * @param {Object} options.video - The associated video object. + * @param {Object} options.profile - The creator's profile object. + * @param {string} [options.variant] - UI variant (e.g., "compact"). + * @returns {HTMLElement} The created article element representing the history card. + */ export function buildHistoryCard({ item, video, profile, variant }) { const isCompact = variant === "compact" || variant === "modal"; @@ -1433,6 +1443,12 @@ export function buildHistoryCard({ item, video, profile, variant }) { return article; } +/** + * Factory function that creates a stateful renderer object to manage the history grid. + * + * @param {Object} [config={}] - Overrides for DOM selectors, fetch strategies, and batch sizes. + * @returns {Object} An object with lifecycle methods (init, refresh, loadMore, destroy) and event handlers. + */ export function createWatchHistoryRenderer(config = {}) { let hasLoggedFeedRegistrationFallback = false; const { @@ -2594,6 +2610,12 @@ export function createWatchHistoryRenderer(config = {}) { const watchHistoryRenderer = createWatchHistoryRenderer(); +/** + * Entry point intended to be called when the watch history page/view is initialized. + * Attaches info popovers and initializes the default watch history renderer. + * + * @returns {Promise} + */ export async function initHistoryView() { const infoTrigger = document.getElementById("historyInfoTrigger"); if (infoTrigger) { diff --git a/memory-update.md b/memory-update.md index 218459ce..d4a36b87 100644 --- a/memory-update.md +++ b/memory-update.md @@ -1,3 +1,3 @@ -- The `todo-triage-agent` successfully ran but found 0 actionable TODOs in the codebase (excluding vendor files). -- The regex used `grep -n -E "TODO|FIXME|XXX" -- '*.js' '*.html' 'docs/*'` correctly filtered the files. -- The `js/ui/profileModalContract.js` match was a string literal description, not a comment. +- The `docs-code-investigator` successfully analyzed and documented `js/historyView.js`. +- JSDoc annotations were appended to the `js/historyView.js` public API to adhere to the strict `no-behavioral-changes` constraint. +- A comprehensive overview markdown file was successfully created at `docs/historyView-overview.md`. \ No newline at end of file diff --git a/src/context/CONTEXT_2026-03-02T19-16-57Z.md b/src/context/CONTEXT_2026-03-02T19-16-57Z.md new file mode 100644 index 00000000..0ff08ec8 --- /dev/null +++ b/src/context/CONTEXT_2026-03-02T19-16-57Z.md @@ -0,0 +1,24 @@ +# Context: Documenting js/historyView.js + +## Goal +Identify, analyze, and document the `js/historyView.js` source file.
