@magicpages/ghost-typesense-webhook

A Netlify Function that keeps your Typesense search index in sync with your Ghost content.

Quick Setup

1. Deploy to Netlify:


2. Set environment variables in Netlify:

``bash
GHOST_URL=https://your-ghost-blog.com
GHOST_CONTENT_API_KEY=your-content-api-key
TYPESENSE_HOST=your-typesense-host
TYPESENSE_API_KEY=your-admin-api-key
COLLECTION_NAME=ghost
WEBHOOK_SECRET=your-secret-key # Create a secure random string
`

3. Add webhooks in Ghost Admin:
- Go to Settings → Integrations
- Create/select a Custom Integration
- Add the following four webhooks:
| Name | Event | Target URL |
|------|-------|------------|
| Post published | Post published | https://your-site.netlify.app/.netlify/functions/handler?secret=your-secret-key |
| Post updated | Post updated | https://your-site.netlify.app/.netlify/functions/handler?secret=your-secret-key |
| Post deleted | Post deleted | https://your-site.netlify.app/.netlify/functions/handler?secret=your-secret-key |
| Post unpublished | Post unpublished | https://your-site.netlify.app/.netlify/functions/handler?secret=your-secret-key |

Manual Setup

1. Install the package:
`bash
npm install @magicpages/ghost-typesense-webhook
`

2. Create the function:
`typescript
// netlify/functions/handler.ts
import { handler } from '@magicpages/ghost-typesense-webhook';
export { handler };
`

3. Configure netlify.toml:
`toml
[functions]
directory = "netlify/functions"
node_bundler = "esbuild"
`

Environment Variables

| Variable | Description |
|----------|-------------|
| GHOST_URL | Your Ghost blog URL |
| GHOST_CONTENT_API_KEY | Content API key from Ghost |
| TYPESENSE_HOST | Typesense host |
| TYPESENSE_API_KEY | Typesense admin API key |
| COLLECTION_NAME | Collection name (default: 'ghost') |
| WEBHOOK_SECRET` | Secret key for webhook security |

How It Works

The webhook handler:
1. Validates the secret in the URL query parameter
2. Processes post status changes (publish/unpublish/update)
3. Updates the Typesense index accordingly
4. Automatically generates plaintext content from HTML for better search quality
5. Ensures content is properly formatted for optimal search results

$3

When a post is published or updated, the handler:

1. Fetches complete data: Gets the full post details from Ghost including tags and authors
2. Transforms content:
- Converts timestamps to numeric formats for sorting
- Extracts tag and author information
- Generates clean plaintext content from HTML by:
- Removing script and style tags with their content
- Replacing HTML tags with spaces to preserve word boundaries
- Normalizing whitespace
- Creating a clean, searchable text version
3. Updates index: Adds or updates the document in Typesense with the transformed content
4. Optimizes for search: Ensures the content is indexed in a way that enables:
- Context-aware search result highlighting
- Relevant excerpts showing search terms in context
- Accurate full-text search across all content

This automatic transformation ensures that your search index stays in sync with your Ghost content while providing the best possible search experience for your users.
