[medsabbar]

This pull request sets up a full-stack React Router template with MongoDB integration, including Docker support, a basic todo application, and modern development tooling. The main changes introduce a ready-to-deploy project structure, backend model and routes for todos, frontend styling, and documentation for usage and deployment.

Project Setup & Tooling

• Added Dockerfile, .dockerignore, and updated .gitignore to support containerized development and deployment, ignoring build artifacts and dependencies. [1] [2] [3]
• Added a comprehensive README.md detailing features, setup instructions, and deployment options.

Backend & Data Layer

• Implemented a Mongoose Todo model in app/model/todo.ts with schema, serialization, and type definitions for todo items.

Routing & API Endpoints

• Defined application routes in app/routes.ts for home, todos list, create, toggle, and delete operations.
• Added backend logic for creating, deleting, and toggling todos in respective route files, connecting to MongoDB and handling errors. [1] [2] [3] [4]

Frontend & Styling

• Added base Tailwind CSS styling in app/app.css for modern UI and dark mode support.
• Implemented root layout, error boundary, and page-level meta configuration for a clean React Router experience in app/root.tsx and app/routes/home.tsx. [1] [2]
