Prompt: Social Media Feed Infinite Scroll (FPC006)
Model: Groq-Gemma2-9b | Date: 05/17/2025 | Page Title: Social Feed
Prompt Description
Simulate a social media feed (like Twitter/X or Facebook) with posts and **infinite scrolling** to load more posts.
**Page Structure & Features:**
1. **Main Layout:** Header (simple title), Main content area for the feed, Footer (optional).
2. **Post Component:** Each post in the feed should display:
* User Avatar and Name.
* Post Timestamp.
* Post Content (text, maybe a placeholder for an image).
* Action buttons: 'Like' (with count, toggles `aria-pressed`), 'Comment' (no action needed), 'Share' (no action needed).
* Each post identifiable as `data-testid='feed-post-N'`.
* Like button on each post: `data-testid='like-btn-postN'`.
3. **Feed Container (`data-testid='social-feed-container'`):**
* Initially load a set of (e.g., 5-10) posts.
* **Infinite Scroll:** As the user scrolls towards the bottom of the feed container, new posts should be dynamically fetched (simulated by JS, no actual API call needed, just append more generated post elements) and added to the feed.
* A loading indicator (`data-testid='feed-loading-indicator'`) should be visible while new posts are being 'fetched' and appended.
**Technical & Accessibility Requirements:**
* Semantic HTML. Posts could be `<article>` elements.
* The infinite scroll MUST NOT break keyboard navigation or trap focus. Users should still be able to navigate through all loaded posts using the keyboard.
* New content loaded via infinite scroll should be announced to assistive technologies if possible (e.g., using an `aria-live` region that briefly states 'More posts loaded').
* The 'Like' button interaction should be fully accessible.
* The page must be responsive.
* Styling: Tailwind CSS primarily. Custom JS is essential for the infinite scroll logic, post generation, like button state, and loading indicator.
**Testing Identifiers:**
* Feed Container: `data-testid='social-feed-container'`
* An individual Post: `data-testid='feed-post-1'` (example)
* Like button on a post: `data-testid='like-btn-post1'` (example)
* Loading Indicator: `data-testid='feed-loading-indicator'`
* ARIA Live region for new content: `data-testid='feed-update-announcer'` (optional but good)
