Trello Web (Node.js + Express.js + MongoDB)

A lightweight, modular Express.js API for a Trello-style kanban app. Handles boards, columns, cards, and drag-and-drop reordering. Runs on Node.js + MongoDB (Atlas) and deploys smoothly to Render.

---

Features

• RESTful resources: boards / columns / cards.
• Robust reorder endpoints for columns & cards (within/between columns).
• Input validation & error handling.
• CORS (allowlist) for the Vercel frontend.
• Production-safe Mongo connection & env validation.

---

Tech

• Node.js 18+ + Express.js + Joi
• MongoDB Atlas (Database)
• ESLint (babel parser)
• Babel (preset-env, runtime) + Nodemon (Build/Run)
• Deploy: Render
