📦 Installation

npm install @apiclient.xyz/ghost

Or with pnpm:

pnpm install @apiclient.xyz/ghost

🎯 Quick Start

import { Ghost } from '@apiclient.xyz/ghost';

const ghost = new Ghost({
  baseUrl: 'https://your-ghost-site.com',
  contentApiKey: 'your_content_api_key',  // Optional: only needed for reading
  adminApiKey: 'your_admin_api_key'       // Required for write operations
});

// Read posts
const posts = await ghost.getPosts({ limit: 10 });
posts.forEach(post => console.log(post.getTitle()));

// Create a post
const newPost = await ghost.createPost({
  title: 'Hello World',
  html: '<p>My first post!</p>',
  status: 'published'
});

// Update it
await newPost.update({
  title: 'Hello World - Updated!'
});

That's it. No complicated setup, no boilerplate. Just pure Ghost API goodness. 🎉

📚 Core API

🔑 Authentication & Setup

Initialize the Ghost client with your API credentials:

const ghost = new Ghost({
  baseUrl: 'https://your-ghost-site.com',
  contentApiKey: 'your_content_api_key',  // For reading public content
  adminApiKey: 'your_admin_api_key'       // For write operations
});

📝 Posts

Get All Posts

const posts = await ghost.getPosts();

posts.forEach(post => {
  console.log(post.getTitle());
  console.log(post.getExcerpt());
  console.log(post.getFeatureImage());
});

Filter Posts

const techPosts = await ghost.getPosts({ 
  tag: 'technology',
  limit: 10 
});

const featuredPosts = await ghost.getPosts({ 
  featured: true,
  limit: 5 
});

const authorPosts = await ghost.getPosts({ 
  author: 'john-doe' 
});

Get Single Post

const post = await ghost.getPostById('post-id');
console.log(post.getTitle());
console.log(post.getHtml());
console.log(post.getAuthor());

Create Post

const newPost = await ghost.createPost({
  title: 'My Awesome Post',
  html: '<p>This is the content of my post.</p>',
  feature_image: 'https://example.com/image.jpg',
  tags: [{ id: 'tag-id' }],
  excerpt: 'A brief summary of the post'
});

Or create from HTML specifically:

const post = await ghost.createPostFromHtml({
  title: 'My HTML Post',
  html: '<p>Content here</p>'
});

Update Post

const post = await ghost.getPostById('post-id');
await post.update({
  ...post.toJson(),
  title: 'Updated Title',
  html: '<p>Updated content</p>'
});

Delete Post

const post = await ghost.getPostById('post-id');
await post.delete();

Search Posts

Full-text search across post titles:

const results = await ghost.searchPosts('typescript tutorial', { limit: 10 });
results.forEach(post => console.log(post.getTitle()));

Get posts with similar tags:

const post = await ghost.getPostById('post-id');
const related = await ghost.getRelatedPosts(post.getId(), 5);
related.forEach(p => console.log(`Related: ${p.getTitle()}`));

Bulk Operations

await ghost.bulkUpdatePosts(['id1', 'id2', 'id3'], {
  featured: true
});

await ghost.bulkDeletePosts(['id4', 'id5', 'id6']);

📄 Pages

Pages work similarly to posts but are for static content:

const pages = await ghost.getPages();

const aboutPage = await ghost.getPageBySlug('about');
console.log(aboutPage.getHtml());

const newPage = await ghost.createPage({
  title: 'Contact',
  html: '<p>Contact information...</p>'
});

await newPage.update({
  html: '<p>Updated content</p>'
});

await newPage.delete();

Filter pages with minimatch patterns:

const filteredPages = await ghost.getPages({ 
  filter: 'about*',
  limit: 10 
});

🏷️ Tags

Get All Tags

// Get ALL tags (including those with zero posts)
const tags = await ghost.getTags();
tags.forEach(tag => console.log(`${tag.name} (${tag.slug})`));

Note: Uses Admin API to fetch ALL tags, including tags with zero posts. Previous versions using Content API would omit tags with no associated content.

Filter by Visibility

Ghost supports two tag types:

Public tags: Standard tags visible to readers
Internal tags: Tags prefixed with # for internal organization (not visible publicly)

// Get only public tags
const publicTags = await ghost.getPublicTags();

// Get only internal tags (e.g., #feature, #urgent)
const internalTags = await ghost.getInternalTags();

// Get all tags with explicit visibility filter
const publicTags = await ghost.getTags({ visibility: 'public' });
const internalTags = await ghost.getTags({ visibility: 'internal' });
const allTags = await ghost.getTags({ visibility: 'all' }); // default

Filter Tags with Minimatch

const techTags = await ghost.getTags({ filter: 'tech-*' });
const blogTags = await ghost.getTags({ filter: '*blog*' });

// Combine visibility and pattern filtering
const internalNews = await ghost.getTags({
  filter: 'news-*',
  visibility: 'internal'
});

Get Single Tag

const tag = await ghost.getTagBySlug('javascript');
console.log(tag.getName());
console.log(tag.getDescription());
console.log(tag.getVisibility()); // 'public' or 'internal'

// Check visibility
if (tag.isInternal()) {
  console.log('This is an internal tag');
}

Create, Update, Delete Tags

// Create a public tag
const newTag = await ghost.createTag({
  name: 'TypeScript',
  slug: 'typescript',
  description: 'All about TypeScript',
  visibility: 'public'
});

// Create an internal tag (note the # prefix)
const internalTag = await ghost.createTag({
  name: '#feature',
  slug: 'hash-feature',
  visibility: 'internal'
});

// Update tag
await newTag.update({
  description: 'Everything TypeScript related'
});

// Delete tag (now works reliably!)
await newTag.delete();

👤 Authors

Get Authors

const authors = await ghost.getAuthors();
authors.forEach(author => {
  console.log(`${author.getName()} (${author.getSlug()})`);
});

Filter Authors

const filteredAuthors = await ghost.getAuthors({ 
  filter: 'j*',
  limit: 10 
});

Get Single Author

const author = await ghost.getAuthorBySlug('john-doe');
console.log(author.getBio());
console.log(author.getProfileImage());

Update Author

await author.update({
  bio: 'Updated bio information',
  website: 'https://johndoe.com'
});

👥 Members

Manage your Ghost site members (requires Ghost membership features):

Get Members

const members = await ghost.getMembers({ limit: 100 });
members.forEach(member => {
  console.log(`${member.getName()} - ${member.getEmail()}`);
  console.log(`Status: ${member.getStatus()}`);
});

Filter Members

const gmailMembers = await ghost.getMembers({ 
  filter: '*@gmail.com' 
});

Get Single Member

const member = await ghost.getMemberByEmail('user@example.com');
console.log(member.getStatus());
console.log(member.getLabels());

Create Member

const newMember = await ghost.createMember({
  email: 'newuser@example.com',
  name: 'New User',
  note: 'VIP member'
});

Update and Delete Members

await member.update({
  name: 'Updated Name',
  note: 'Premium member'
});

await member.delete();

🪝 Webhooks

Manage webhooks for Ghost events:

const webhook = await ghost.createWebhook({
  event: 'post.published',
  target_url: 'https://example.com/webhook',
  name: 'Post Published Webhook'
});

await ghost.updateWebhook(webhook.id, {
  target_url: 'https://example.com/new-webhook'
});

await ghost.deleteWebhook(webhook.id);

Note: The Ghost Admin API only supports creating, updating, and deleting webhooks. Browsing and reading individual webhooks are not supported by the underlying SDK.

🖼️ Image Upload

Upload images to your Ghost site:

const imageUrl = await ghost.uploadImage('/path/to/image.jpg');

await ghost.createPost({
  title: 'Post with Image',
  html: '<p>Content here</p>',
  feature_image: imageUrl
});

🔄 Multi-Instance Synchronization

The SyncedInstance class enables you to synchronize content across multiple Ghost instances - perfect for staging environments, multi-region deployments, or content distribution.

Key Features:

🔒 Same-Instance Protection - Automatically prevents circular syncs that would cause excessive API calls
🏷️ Slug Congruence - Ensures slugs remain consistent across all synced instances
🗺️ ID Mapping - Tracks source-to-target ID mappings for efficient updates
📊 Detailed Reporting - Get comprehensive sync reports with success/failure counts

Setup

import { Ghost, SyncedInstance } from '@apiclient.xyz/ghost';

const sourceGhost = new Ghost({
  baseUrl: 'https://source.ghost.com',
  contentApiKey: 'source_content_key',
  adminApiKey: 'source_admin_key'
});

const targetGhost1 = new Ghost({
  baseUrl: 'https://target1.ghost.com',
  contentApiKey: 'target1_content_key',
  adminApiKey: 'target1_admin_key'
});

const targetGhost2 = new Ghost({
  baseUrl: 'https://target2.ghost.com',
  contentApiKey: 'target2_content_key',
  adminApiKey: 'target2_admin_key'
});

// This will throw an error if you accidentally try to sync an instance to itself
const synced = new SyncedInstance(sourceGhost, [targetGhost1, targetGhost2]);

Safety Note: SyncedInstance validates that the source and target instances are different. Attempting to sync an instance to itself will throw an error immediately, preventing circular syncs and rate limit issues.

Sync Content

const tagReport = await synced.syncTags();
console.log(`Synced ${tagReport.totalItems} tags`);
console.log(`Duration: ${tagReport.duration}ms`);

const postReport = await synced.syncPosts();
console.log(`Success: ${postReport.targetReports[0].successCount}`);
console.log(`Failed: ${postReport.targetReports[0].failureCount}`);

const pageReport = await synced.syncPages();

Sync Options

const report = await synced.syncPosts({
  filter: 'featured-*',
  dryRun: true,
  incremental: true
});

report.targetReports.forEach(targetReport => {
  console.log(`Target: ${targetReport.targetUrl}`);
  targetReport.results.forEach(result => {
    console.log(`  ${result.sourceSlug}: ${result.status}`);
  });
});

Sync Everything

const reports = await synced.syncAll({
  types: ['tags', 'posts', 'pages'],
  syncOptions: {
    dryRun: false
  }
});

reports.forEach(report => {
  console.log(`${report.contentType}: ${report.totalItems} items`);
});

Sync Status & History

const status = synced.getSyncStatus();
console.log(`Total mappings: ${status.totalMappings}`);
console.log(`Recent syncs: ${status.recentSyncs.length}`);

status.mappings.forEach(mapping => {
  console.log(`Source: ${mapping.sourceSlug}`);
  mapping.targetMappings.forEach(tm => {
    console.log(`  -> ${tm.targetUrl} (${tm.targetId})`);
  });
});

synced.clearSyncHistory();
synced.clearMappings();

🎨 Complete Example

Here's a comprehensive example showing various operations:

import { Ghost, SyncedInstance } from '@apiclient.xyz/ghost';

const ghost = new Ghost({
  baseUrl: 'https://your-ghost-site.com',
  contentApiKey: 'your_content_key',
  adminApiKey: 'your_admin_key'
});

async function createBlogPost() {
  // Upload a feature image
  const imageUrl = await ghost.uploadImage('./banner.jpg');

  // Create a tag for categorization
  const tag = await ghost.createTag({
    name: 'Tutorial',
    slug: 'tutorial',
    description: 'Step-by-step guides',
    visibility: 'public'
  });

  // Create a comprehensive blog post
  const post = await ghost.createPost({
    title: 'Getting Started with Ghost CMS',
    slug: 'getting-started-ghost-cms',
    html: '<h1>Welcome</h1><p>This is an introduction to Ghost CMS...</p>',
    feature_image: imageUrl,
    tags: [{ id: tag.getId() }],
    featured: true,
    status: 'published',
    meta_title: 'Getting Started with Ghost CMS | Tutorial',
    meta_description: 'Learn how to get started with Ghost CMS in this comprehensive guide',
    custom_excerpt: 'A beginner-friendly guide to Ghost CMS'
  });

  console.log(`✅ Created post: ${post.getTitle()}`);
  console.log(`📅 Published at: ${post.postData.published_at}`);

  // Find related content
  const related = await ghost.getRelatedPosts(post.getId(), 5);
  console.log(`🔗 Found ${related.length} related posts`);

  // Search functionality
  const searchResults = await ghost.searchPosts('getting started', { limit: 10 });
  console.log(`🔍 Search found ${searchResults.length} posts`);

  // Get all public tags
  const publicTags = await ghost.getPublicTags();
  console.log(`🏷️  Public tags: ${publicTags.length}`);

  return post;
}

async function syncToStaging() {
  // Sync content to staging environment
  const production = new Ghost({
    baseUrl: 'https://production.ghost.com',
    adminApiKey: process.env.PROD_ADMIN_KEY,
    contentApiKey: process.env.PROD_CONTENT_KEY
  });

  const staging = new Ghost({
    baseUrl: 'https://staging.ghost.com',
    adminApiKey: process.env.STAGING_ADMIN_KEY,
    contentApiKey: process.env.STAGING_CONTENT_KEY
  });

  const synced = new SyncedInstance(production, [staging]);

  // Sync everything
  const reports = await synced.syncAll({
    types: ['tags', 'posts', 'pages']
  });

  reports.forEach(report => {
    console.log(`✅ Synced ${report.totalItems} ${report.contentType} in ${report.duration}ms`);
  });
}

// Run the examples
createBlogPost().catch(console.error);
// syncToStaging().catch(console.error);

⚡ Performance & Best Practices

Rate Limiting

Ghost enforces rate limits on API requests (~100 requests per IP per hour for Admin API). Keep these tips in mind:

// ✅ Good: Batch operations
await ghost.bulkUpdatePosts(['id1', 'id2', 'id3'], { featured: true });

// ❌ Bad: Individual requests in a loop
for (const id of postIds) {
  await ghost.getPostById(id).then(p => p.update({ featured: true }));
}

// ✅ Good: Use pagination efficiently
const posts = await ghost.getPosts({ limit: 15 });

// ✅ Good: Filter on the server side
const featuredPosts = await ghost.getPosts({ featured: true, limit: 10 });

Multi-Instance Sync Safety

The library automatically prevents common pitfalls:

// ✅ This works - different instances
const synced = new SyncedInstance(sourceGhost, [targetGhost]);

// ❌ This throws an error - prevents circular sync!
const synced = new SyncedInstance(ghost, [ghost]); // Error: Cannot sync to same instance

Content API vs Admin API

Content API: Read-only, public content, no authentication required (with Content API key)
Admin API: Full read/write access, requires Admin API key
Tags: This library uses Admin API for tags to fetch ALL tags (Content API only returns tags with posts)

Dry Run Mode

Test your sync operations without making changes:

const report = await synced.syncAll({
  types: ['posts', 'pages', 'tags'],
  syncOptions: {
    dryRun: true  // Preview changes without applying them
  }
});

console.log(`Would sync ${report[0].totalItems} items`);

🔒 Error Handling

All methods throw errors that you can catch and handle:

try {
  const post = await ghost.getPostById('invalid-id');
} catch (error) {
  console.error('Failed to fetch post:', error);
}

try {
  await post.update({ title: 'New Title' });
} catch (error) {
  console.error('Failed to update post:', error);
}

🧪 Testing

pnpm test

📝 TypeScript Support

This library is written in TypeScript and provides full type definitions out of the box. No @types/* package needed.

import type { IPost, ITag, IAuthor, IMember, IPage } from '@apiclient.xyz/ghost';

Date Handling

All date fields (created_at, updated_at, published_at) are returned as ISO 8601 formatted strings with timezone information:

const post = await ghost.getPostById('post-id');

// Date strings are in ISO 8601 format: "2025-10-10T13:54:44.000-04:00"
console.log(post.postData.created_at);    // string
console.log(post.postData.updated_at);    // string
console.log(post.postData.published_at);  // string

// Parse them to Date objects if needed
const publishedDate = new Date(post.postData.published_at);
console.log(publishedDate.toISOString());

Note: Ghost automatically manages updated_at timestamps. When you update metadata fields (title, status, tags, etc.), Ghost updates this timestamp. HTML-only updates may not always change updated_at.
