Installation

npm install payload-plugin-cloudflare-purge
# or
yarn add payload-plugin-cloudflare-purge
# or
pnpm add payload-plugin-cloudflare-purge

Configuration

Basic Setup

Add the plugin to your payload.config.ts:

import { buildConfig } from 'payload'
import { PayloadPluginCloudflarePurge } from 'payload-plugin-cloudflare-purge'

export default buildConfig({
  plugins: [
    PayloadPluginCloudflarePurge({
      enabled: true,
      zoneId: process.env.CLOUDFLARE_ZONE_ID,
      apiToken: process.env.CLOUDFLARE_API_TOKEN,
      baseUrl: 'https://yourdomain.com',
      collections: ['posts', 'pages'],
      globals: ['header', 'footer'], // Target specific globals (case exist)
      showButtonPurgeEverything: true, // Show the manual purge button in dashboard
    }),
  ], // ... other config
})

Environment Variables

CLOUDFLARE_ZONE_ID=your_zone_id_here
CLOUDFLARE_API_TOKEN=your_api_token_here

Advanced Configuration

PayloadPluginCloudflarePurge({
  enabled: true,
  zoneId: process.env.CLOUDFLARE_ZONE_ID,
  apiToken: process.env.CLOUDFLARE_API_TOKEN,
  baseUrl: 'https://yourdomain.com',
  collections: 'ALL', // Purge for all collections
  events: ['afterChange', 'afterDelete'],
  purgeEverything: false,
  showButtonPurgeEverything: true,
  urlBuilder: ({ doc, collectionSlug }) => {
    // Custom URL building logic
    return [`https://yourdomain.com/${collectionSlug}/${doc.slug}`]
  },
  debug: process.env.NODE_ENV === 'development',
  logCFJSON: false,
  useEndpoint: true,
})

API Endpoint

The plugin adds a POST endpoint at /api/cloudflare-purge for manual purge requests:

// Example manual purge request
const response = await fetch('/api/cloudflare-purge', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    Authorization: 'Bearer your_token_here', // If not using internal call
  },
  body: JSON.stringify({
    files: ['/specific-url-to-purge'],
    purgeEverything: false,
  }),
})

Custom URL Builder (Async)

You can provide a custom async function to build URLs, allowing you to fetch additional data needed to create a comprehensive purge list.

import { PayloadPluginCloudflarePurge } from 'payload-plugin-cloudflare-purge'
import type { UrlBuilderArgs } from 'payload-plugin-cloudflare-purge/types'

PayloadPluginCloudflarePurge({
  // ...
  urlBuilder: async (args: UrlBuilderArgs) => {
    const { doc, previousDoc, req, collectionSlug, baseUrl } = args

    if (collectionSlug === 'posts') {
      // Example: Fetch all category pages this post belongs to
      const category = await req.payload.findByID({
        collection: 'categories',
        id: doc.category.id,
      })

      const urls = [`${baseUrl}/posts/${doc.slug}`]
      if (category) {
        urls.push(`${baseUrl}/categories/${category.slug}`)
      }

      // If slug changed, purge the old URL too
      if (previousDoc && previousDoc.slug && previousDoc.slug !== doc.slug) {
        urls.push(`${baseUrl}/posts/${previousDoc.slug}`)
      }

      return urls
    }

    return []
  },
})

Changelog

v2.4.0 (Latest)

✨ Features

• Dashboard Purge Button: Added a PurgeEverythingButton component that can be optionally injected into the Admin Dashboard. This allows admins to trigger a "Purge Everything" request directly from the UI.
• Configurable UI: Introduced the showButtonPurgeEverything option (default: false) to enable the dashboard button.

🐛 Fixes

• Improved Endpoint Body Parsing: Updated purgeEndpointHandler to correctly handle request bodies in both Next.js Web API environments (using req.json()) and standard Express environments (using req.body). This fixes issues where the manual purge endpoint might fail to read options.

v2.3.0

✨ Features

• Access to Previous Document: The urlBuilder function now receives a previousDoc argument in the afterChange hook. This allows for comparing the document before and after the change, enabling more advanced cache purging logic, such as purging old URLs when a slug is modified.

🛠️ Improvements

• Improved Typing: The req object passed to the urlBuilder is now correctly typed as PayloadRequest.

v2.2.0

✨ Features

• Asynchronous urlBuilder: The urlBuilder function can now be async, allowing for complex logic that needs to fetch data (e.g., querying the Payload API) to build the list of URLs to purge.
• Exported Types: The plugin now properly exports all its types, allowing for a fully typed implementation in your own project via import type { UrlBuilderArgs } from 'payload-plugin-cloudflare-purge/types'.

v2.1.0

✨ Features

• Globals Support: The plugin now automatically purges cache for changes in Payload globals. You can configure this with the new globals: ['my-global'] or globals: 'ALL' option.
• Localization Support: Added a localized: true option. When enabled, the urlBuilder function receives the current locale as a parameter, allowing you to build locale-specific URLs (e.g., /en/my-page).

🛠️ Improvements

• Logging is now conditional on the debug: true flag to provide a cleaner console output in production.
• The successful purge log now includes the request body sent to Cloudflare for easier debugging.

v2.0.0

Breaking Changes

• Switched from default export to named export: use import { PayloadPluginCloudflarePurge } from 'payload-plugin-cloudflare-purge'.
• Removed unused subpath exports: payload-plugin-cloudflare-purge/client and payload-plugin-cloudflare-purge/rsc.

Migration Guide

• Update imports in your payload.config.ts and examples:

// Before
// import PayloadPluginCloudflarePurge from 'payload-plugin-cloudflare-purge'

// After
import { PayloadPluginCloudflarePurge } from 'payload-plugin-cloudflare-purge'

v1.0.3

Bug Fixes

• Fixed circular reference JSON serialization error: Resolved the "Converting circular structure to JSON" error by ensuring hooks return only the document (doc) instead of the complete arguments object (args) which contained circular references between PgTable and PgInteger objects

• Improved hook compatibility: Modified both afterChangeHook and afterDeleteHook to return the document directly, preventing circular reference issues during Payload CMS response serialization

v1.0.2

• Draft-aware purge logic - only purges on actual publication
• Automatic draft configuration detection per collection
• Improved TypeScript examples in documentation

v1.0.1

• Fixed export, main and type scripts by package.json
• Description repository
• Version package
• Add badges version and npm

v1.0.0

• Complete rewrite with TypeScript
• PostgreSQL support instead of MongoDB
• Enhanced configuration options
• Improved error handling and logging
• Internal endpoint for manual purges
• Flexible URL building system
