Feature: Shera Youth Club – Lightweight Online Community App

[azoraadlo-spec]

Is your feature request related to a problem? Please describe

The need for a lightweight, modern online community app for youth—optimized for low resources and accessible to users with limited connectivity. Inspired by Facebook Lite, this would enable youth to stay connected, create groups, share updates, and communicate efficiently.

Describe the solution you'd like

Create Shera Youth Club: a lightweight mobile-first online community platform. Key features should include user sign up/login, profile management, posting (text, images, links), like/comment, friends/connect, feed/timeline, notifications, basic chat, group participation, and robust admin tools—all optimized for performance and usability in low-bandwidth scenarios.

Describe alternatives you've considered

• Building solely for web instead of mobile-first
• Integrating with existing platforms rather than standalone
• Focusing on fewer features for a more minimal MVP

@azoraadlo-spec Hello! Here is an automated response to your question:

Thank you for your detailed feature request for Shera Youth Club, a lightweight, mobile-first online community app for youth. Your vision for accessibility and performance in low-resource, low-bandwidth scenarios is well aligned with modern best practices. Below, we address your core requirements and provide implementation guidance leveraging AntV G/F2 technologies.

---

1. User Sign Up & Profile Management

• Approach: Structure user data and profile UI as lightweight nodes within the app’s scene graph.
• Implementation:
  • Use methods like appendChild, removeChild, and replaceChild to dynamically manage user profile components.
  • Register custom profile graphics with canvas.customElements.define and instantiate them with canvas.document.createElement.
  • For modularity, manage authentication logic separately, and only mount profile nodes for authenticated users.

// Register and create a custom profile element
canvas.customElements.define(ProfileShape.tag, ProfileShape);
const userProfile = canvas.document.createElement(ProfileShape.tag, { ...userData });
scene.appendChild(userProfile);

• Plugin Management: Dynamically enable/disable plugins (e.g., for authentication, social features) with renderer.unregisterPlugin(plugin) and renderer.getPlugins().

---

2. Posting, Likes, and Comments

• Posting:
  • Use text/image/link nodes for post content.
  • Append posts to a feed container using appendChild or bulk operations like append.
  • Render tooltips or overlays (e.g., for image previews or links) with the HTML class.

const post = new HTML({
  style: {
    innerHTML: '<p>My update</p><img src="...">',
    width: 200, height: 80,
  },
});
feedContainer.appendChild(post);

• Likes/Comments:
  • Use interactive event listeners (click, mouseenter) to handle likes and comments efficiently.
  • Update UI with minimal DOM changes for low bandwidth—only re-render the affected post node.

post.addEventListener('click', (e) => {
  // Toggle like/comment
  e.target.style.fill = 'red'; // Simple feedback
});

• Querying/Filtering:
  • Use CSS selectors via the g-plugin-css-select for efficient feed filtering or group queries.

---

3. Notifications, Chat, Group Participation

• Notifications:

  • Use event listeners (inserted, attributeChanged) to trigger notification UI updates only when necessary.
  • Batch notifications in a single overlay node for bandwidth efficiency.

• Chat:

  • Reuse shape/object pools for frequent message node creation/destruction (see object pooling sample below).
  • Attach listeners for touch/pointer events to chat bubbles for seamless mobile interaction.

const chatBubblePool = new BubblePool(50);
// Acquire/release bubbles as messages are sent/received

• Group Participation:
  • Structure groups as logical containers (Group nodes) and use appendChild/removeChild for membership changes.
  • Calculate group bounds and optimize rendering only for visible/active groups.

---

4. Admin Tools & Performance Optimization

• Admin Features: Implement moderation tools as modular plugins for easy enable/disable.

  • Use the plugin API (registerPlugin, unregisterPlugin) for dynamic admin controls.
  • Admin dashboards can be custom node sets, only rendered for authorized users.

• Performance:

  • Renderer Config: Enable dirty rectangle rendering, culling, and auto-rendering in the Canvas renderer for optimal redraws.
  • Layering: Separate static and dynamic content into layers to minimize resource use.
  • Object Pooling: Reuse frequently created objects (e.g., chat bubbles, notifications) to reduce memory and CPU overhead.

const renderer = new CanvasRenderer({
  enableDirtyRectangleRendering: true,
  enableDirtyCheck: true,
  enableCulling: true,
  enableAutoRendering: true,
});
const canvas = new Canvas({ container: 'container', renderer });

Summary Table

Feature	Implementation Highlights
Profile Management	Node APIs (appendChild, custom elements), plugins
Posting	HTML nodes, event listeners, selector queries
Likes/Comments	Event-driven UI updates, lightweight feedback
Notifications/Chat	Object pooling, batching, optimized event handling
Groups	Group nodes, membership via add/remove APIs
Admin Tools	Plugin API, layered scene graphs, manual rendering
Performance	Dirty rect, culling, object pools, layers

---

Next Steps

• Prototype each UI feature with simple data and validate on low-resource devices.
• Use layers and pooling for dynamic content (posts, chat, notifications).
• Continuously test bandwidth and CPU usage, especially on 3G/4G or offline emulation.
