Posts Table

CREATE TABLE Posts (
  id BIGINT PRIMARY KEY GENERATED ALWAYS AS IDENTITY,
  title TEXT NOT NULL,
  content TEXT NOT NULL,
  image_url TEXT,

  UNIQUE(event_id, user_id)
);

Messaging Tables

For the complete messaging schema including conversations, messages, reactions, and real-time features, see database-schema-messaging.sql.

Storage Setup

• Create a bucket named post-images in Supabase Storage
• Create a bucket named message-files in Supabase Storage (private)
• Create a bucket named event-images in Supabase Storage (public)
• Set post-images bucket to public
• Set message-files bucket to private
• Set event-images bucket to public

Running the Project

# Development
npm run dev

# Build
npm run build

# Preview build
npm run preview

# Lint
npm run lint

The app will be available at http://localhost:5173

💬 Setting Up Messaging

For detailed instructions on setting up the real-time messaging system, see MESSAGING_SETUP.md.

Quick setup:

1. Run the SQL schema from database-schema-messaging.sql
2. Create the message-files storage bucket (private)
3. Enable real-time for messaging tables
4. Navigate to /messages to start chatting!

📅 Setting Up Event Management

For detailed instructions on setting up the event management system, see the documentation in /docs/:

• EVENT_SCHEMA.md - Database schema and relationships
• EVENT_API.md - API endpoints and usage
• EVENT_TYPES.md - TypeScript type definitions
• EVENT_INTEGRATION.md - Integration patterns and hooks

Quick setup:

1. Run the SQL schema from docs/EVENT_SCHEMA.md
2. Create the event-images storage bucket (public)
3. Navigate to /events to start creating events!

📝 Code Style

TypeScript Guidelines

• Use explicit type annotations
• Avoid any type
• Create interfaces for data structures
• Use strict mode

React Guidelines

• Use functional components with hooks
• Keep components focused and reusable
• Use proper TypeScript types for props
• Avoid inline styles (use Tailwind)

Naming Conventions

• Components: PascalCase (e.g., PostItem.tsx)
• Functions: camelCase (e.g., fetchPosts)
• Constants: UPPER_SNAKE_CASE (e.g., MAX_ITEMS)
• Files: Match component/function name or use kebab-case

Formatting

# Format code
npm run format

# Lint and fix
npm run lint -- --fix

🔄 Git Workflow

Example:

feat: add nested comments support

Implemented multi-level comment threads with collapse/expand functionality.
Added CommentItem component to handle recursive rendering.

Closes #123

🔧 Key Components

Authentication (AuthContext.tsx)

Manages user authentication state including email/password login, GitHub OAuth, logout, password reset, and profile session handling.

const { signInWithGithub, signOut, user, isLoading } = useAuth();

Posts (PostItem.tsx, PostList.tsx)

Displays individual posts and collections of posts with lazy loading.

Comments (CommentItem.tsx, CommentSection.tsx)

Handles nested comment threads with real-time updates using TanStack Query.

Like System (LikeButton.tsx)

Manages post votes with optimistic updates and cache invalidation.

Communities (CommunityList.tsx, CommunityDisplay.tsx)

Shows community listings and posts within communities.

User Account Pages

• /signin – Email & GitHub login
• /signup – Create account
• /reset-password – Password recovery
• /profile – User profile dashboard

📊 Database Schema

Key Relationships

• Users → Posts (1:N)
• Posts → Comments (1:N)
• Comments → Comments (1:N, self-referencing for nested replies)
• Posts → Communities (N:1)
• Posts → Votes (1:N)
• Events → Users (organizer_id): Many-to-One
• Events → Communities (community_id): Many-to-One (optional)
• Events → EventAttendees: One-to-Many
• EventAttendees → Users: Many-to-One

Query Patterns

Get posts with community info:

SELECT *, Communities(name) FROM Posts

Get comments with nested structure:

SELECT * FROM Comments WHERE post_id = ? ORDER BY created_at

Get likes for a post:

SELECT COUNT(*) FROM Votes WHERE post_id = ? AND vote = 1

🛠 Common Tasks

Adding a New Feature

1. Create components in src/components/
2. Create page (if needed) in src/pages/
3. Update routing in App.tsx
4. Add data fetching using TanStack Query
5. Style with Tailwind CSS
6. Test thoroughly
7. Update documentation

Making an API Call

import { useQuery } from '@tanstack/react-query';
import { supabase } from '../supabase-client';

const { data, isLoading, error } = useQuery({
  queryKey: ['posts'],
  queryFn: async () => {
    const { data, error } = await supabase
      .from('Posts')
      .select('*')
      .order('created_at', { ascending: false });
    
    if (error) throw new Error(error.message);
    return data;
  }
});

Adding Styling

Use Tailwind CSS classes:

<div className="bg-slate-900/50 border border-slate-800 rounded-lg p-4">
  <h2 className="text-xl font-semibold text-white">Title</h2>
</div>

🐛 Troubleshooting

Issue: "Could not find the table in schema cache"

Solution: Table names are case-sensitive. Ensure you're using the correct casing (e.g., Comments, not comments).

Issue: Images not uploading

Solution: Check that the post-images bucket exists in Supabase Storage and is set to public.

Issue: Authentication not working

Solution: Verify GitHub OAuth credentials are correctly set in Supabase and the callback URL matches your app URL.

Issue: Comments not loading

Solution: Check database permissions in Supabase. Ensure RLS policies allow reading comments.

Issue: Build errors

Solution:

# Clear node modules and reinstall
rm -rf node_modules package-lock.json
npm install
npm run build
