Give your headless CMS a powerful drag-and-drop editor

GrapesJS fills the editor gap in headless architecture. It provides a rich visual interface that stores content directly in your headless CMS via API — while your frontend (Next.js, Nuxt, SvelteKit) fetches and renders independently. GJS.Market plugins handle the storage adapter plumbing so you can ship faster.

Headless editor architecture

01

Editor layer

GrapesJS provides the visual editing UI. Editors drag and drop blocks, customize styles, and publish — all inside your app.

02

Storage layer

Storage adapters send content to your headless CMS on save and load — REST, GraphQL, or custom API.

03

Content model

GrapesJS serializes to JSON — store the component tree, styles, and HTML in your CMS content model.

04

Delivery layer

Your frontend fetches from the CMS API and renders independently. The editor is invisible to end users.

Any CMS with a REST or GraphQL API is compatible. The storage adapter pattern is CMS-agnostic.

Implementation blueprint

1

Configure storage adapters

Point GrapesJS storage manager to your headless CMS API endpoints for both load and save operations.

2

Define your content model

Map GrapesJS component types to your CMS content schema fields — blocks, rich text, media, and metadata.

3

Set up asset pipeline

Connect S3, Cloudinary, or your CDN for signed media uploads and optimized delivery.

4

Build preview and publish flow

Implement draft and publish states with live preview so editors can verify content before it goes live.

Quick start: connect GrapesJS to your CMS

// 1. Install GrapesJS and storage plugin
npm install grapesjs grapesjs-plugin-storage-rest

// 2. Configure headless CMS storage adapter
const editor = grapesjs.init({
  container: '#editor',
  storageManager: {
    type: 'remote',
    urlStore: 'https://your-cms.io/api/content/{id}',
    urlLoad: 'https://your-cms.io/api/content/{id}',
    fetchOptions: (opts) => ({
      ...opts,
      headers: { Authorization: `Bearer ${token}` },
    }),
  },
});

// 3. Serialize to JSON for headless delivery
const content = editor.getComponents().toJSON();
await fetch('/api/cms/pages', {
  method: 'POST',
  body: JSON.stringify(content),
});
