Framer CMS Plugin — Managed Collections

Examples

Create a fictional staging collection, approve its fields and publishing audience, then publish one canary entry. Verify a duplicate sync is suppressed and an unapproved destination receives neither content nor visitor data.

Overview

Build a Framer plugin that syncs external data into CMS Managed Collections. Managed Collections are plugin-controlled — your plugin creates the schema and populates items. This is the primary integration pattern for connecting Framer to external CMSes, databases, or APIs.

Prerequisites

• Completed framer-install-auth setup
• Plugin dev server running
• Understanding of Framer CMS concepts

Instructions

Step 1: Create a Managed Collection

// src/App.tsx — CMS sync plugin
import { framer } from 'framer-plugin';
import { useState } from 'react';

framer.showUI({ width: 340, height: 400, title: 'Content Sync' });

export function App() {
  const [status, setStatus] = useState('');

  const syncCollection = async () => {
    setStatus('Fetching data...');
    const response = await fetch('https://jsonplaceholder.typicode.com/posts');
    const posts = await response.json();

    setStatus('Creating collection...');
    const collection = await framer.createManagedCollection({
      name: 'Blog Posts',
      fields: [
        { id: 'title', name: 'Title', type: 'string' },
        { id: 'body', name: 'Body', type: 'formattedText' },
        { id: 'author', name: 'Author', type: 'string' },
        { id: 'slug', name: 'Slug', type: 'slug', userEditable: false },
      ],
    });

    setStatus(`Syncing ${posts.length} items...`);
    const items = posts.slice(0, 20).map((post: any) => ({
      fieldData: {
        title: post.title,
        body: `<p>${post.body}</p>`,
        author: `User ${post.userId}`,
        slug: post.title.toLowerCase().replace(/[^a-z0-9]+/g, '-').slice(0, 50),
      },
    }));

    await collection.setItems(items);
    setStatus(`Synced ${items.length} posts`);
    framer.notify(`Synced ${items.length} blog posts`);
  };

  return (
    <div style={{ padding: 16 }}>
      <h3>Blog Post Sync</h3>
      <button onClick={syncCollection} style={{ width: '100%', padding: 8 }}>Sync Now</button>
      {status && <p style={{ marginTop: 8, fontSize: 13, color: '#666' }}>{status}</p>}
    </div>
  );
}

Step 2: Handle CMS Field Types

// Framer CMS field types reference
const fields = [
  { id: 'title', name: 'Title', type: 'string' as const },
  { id: 'content', name: 'Content', type: 'formattedText' as const },
  { id: 'price', name: 'Price', type: 'number' as const },
  { id: 'featured', name: 'Featured', type: 'boolean' as const },
  { id: 'publishDate', name: 'Published', type: 'date' as const },
  { id: 'heroImage', name: 'Hero', type: 'image' as const },
  { id: 'category', name: 'Category', type: 'enum' as const, cases: [
    { id: 'tech', name: 'Technology' },
    { id: 'design', name: 'Design' },
  ]},
  { id: 'slug', name: 'Slug', type: 'slug' as const, userEditable: false },
];

Step 3: Incremental Sync with Change Detection

async function incrementalSync(collection: ManagedCollection, newData: any[]) {
  const existing = await collection.getItems();
  const existingMap = new Map(existing.map(i => [i.fieldData.slug, i]));
  const toUpsert = newData.map(item => {
    const match = existingMap.get(item.slug);
    return match ? { ...item, id: match.id } : item;
  });
  await collection.setItems(toUpsert);
}

Step 4: Unmanaged Collection Access

// Read from user-created CMS collections (not plugin-managed)
const collections = await framer.getCollections();
for (const col of collections) {
  if (col.type === 'unmanaged') {
    const items = await col.getItems();
    console.log(`${col.name}: ${items.length} items`);
  }
}

Output

• Managed CMS collection with typed fields
• External data synced into Framer CMS
• Incremental sync support
• Image auto-upload from URLs
