🚀 Next Steps to Complete Implementation

1. Add Notification Bell to Header

Edit your main header/navbar component:

import NotificationBell from '@/components/notifications/NotificationBell'

export default function Header() {
  return (
    <header>
      {/* ... other header elements ... */}
      <NotificationBell />
    </header>
  )
}

2. Create Notifications on User Actions

In your like/comment/follow handlers:

// When user likes a post
await fetch('/api/notifications/create', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    userId: post.user_id,  // Post author
    type: 'like',
    entityType: 'post',
    entityId: post.id,
  })
})

// When user comments
await fetch('/api/notifications/create', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    userId: post.user_id,
    type: 'comment',
    entityType: 'post',
    entityId: post.id,
  })
})

// When user follows
await fetch('/api/notifications/create', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    userId: targetUserId,
    type: 'follow',
  })
})

3. Add Moderation to Post Creation

In your post creation flow:

import { moderateContent, shouldBlockContent } from '@/lib/moderation'

async function createPost(content: string, imageUrl?: string) {
  // Check content before posting
  const moderationResult = await moderateContent(content, imageUrl)

  if (shouldBlockContent(moderationResult)) {
    throw new Error('Content violates community guidelines')
  }

  // Create post with warnings if flagged
  const post = await supabase.from('posts').insert({
    content,
    image_url: imageUrl,
    content_warnings: moderationResult.warnings,  // Add this field to posts table
    is_sensitive: moderationResult.flagged,       // Add this field too
  })
}

4. Apply Content Warnings in Display

In your PostCard or content display component:

import SensitiveContentWarning from '@/components/moderation/SensitiveContentWarning'

export default function PostCard({ post }) {
  return (
    <div>
      {post.is_sensitive ? (
        <SensitiveContentWarning warnings={post.content_warnings} type="image">
          <img src={post.image_url} alt="Post" />
        </SensitiveContentWarning>
      ) : (
        <img src={post.image_url} alt="Post" />
      )}
    </div>
  )
}

5. Run Database Migration

Apply the notifications schema:

# If using Supabase CLI
supabase db push

# Or apply the SQL file directly in Supabase dashboard
# SQL Editor > Copy contents from:
# supabase/migrations/20251114000001_create_notifications.sql

6. Add Environment Variables

Add to your .env.local:

# OpenAI Moderation API
OPENAI_API_KEY=sk-your-openai-api-key

# Optional: Enable image moderation
ENABLE_IMAGE_MODERATION=false

# Email service (when implementing email notifications)
# SENDGRID_API_KEY=your_sendgrid_key
# or
# AWS_SES_ACCESS_KEY=your_aws_key
# AWS_SES_SECRET_KEY=your_aws_secret

7. Update Posts Table Schema

Add these columns to your posts table:

ALTER TABLE posts
ADD COLUMN IF NOT EXISTS content_warnings TEXT[],
ADD COLUMN IF NOT EXISTS is_sensitive BOOLEAN DEFAULT FALSE;

    template: getEmailTemplate(type, { actor, entity }),
  })
}
