Headless CMS with a Visual Page Builder

This project is an expert-level, full-stack Headless Content Management System (CMS) with a powerful visual page builder. The backend, built with Node.js, Express, and MongoDB, serves content through a sophisticated GraphQL API. The frontend is a feature-rich admin panel built in React, with its core being a drag-and-drop interface that allows non-technical users to visually construct web pages from a library of pre-defined components. The system is architected to be 'headless,' meaning the content is decoupled from the presentation layer, allowing it to be consumed by any frontend application (web, mobile, etc.).

Core Requirements & Features:

• Backend (Node.js/Express/MongoDB): A robust server providing a GraphQL API (using Apollo Server) for all content, user, and asset management.
• Content Modeling: A flexible system in MongoDB to define different content structures, primarily for pages and reusable components.
• GraphQL API: Comprehensive API with queries for fetching content and mutations for creating, updating, and deleting content, users, and pages.
• Admin Panel (React): A secure, single-page application for administrators and editors.
• Visual Page Builder: A drag-and-drop canvas (react-beautiful-dnd) where users can assemble pages by adding, removing, and reordering components.
• Component Library: A set of reusable React components (Hero, Text Block, Image Gallery, etc.) that power the visual builder.
• Dynamic Content Editing: An inline or modal-based editing experience to populate the content of each component added to a page.
• Asset Management: A media library for uploading and managing images and other assets.
• Authentication & Authorization: A role-based access control system (e.g., Admin, Editor) using JWT to secure the admin panel and API endpoints.
• Consumer Frontend: A separate example application (e.g., Next.js) that fetches and renders a page built with the CMS, demonstrating the headless architecture.

Enhancements for Portfolio/Business Scope: To elevate this project to a professional standard, we will incorporate advanced features such as content versioning (allowing rollback to previous page states), webhooks to trigger external build processes (like rebuilding a static site on Vercel), and a full deployment pipeline for both the backend and frontend applications.
