# Todo App Frontend

This is a standalone Node.js server that serves the Todo application's web interface.

## Standalone Setup
1. Clone this repository.
2. Install dependencies:
   ```bash
   npm install
   ```
3. Start the server:
   ```bash
   npm start
   ```
   The frontend runs on port `3000` by default.

## Connecting to Backend
The frontend needs to know where the Backend API is hosted.
- **Development**: Defaults to `http://localhost:3001`.
- **Production**: Set the `BACKEND_URL` environment variable when starting the server.
  ```bash
  BACKEND_URL=https://api.yourdomain.com npm start
  ```

## Deployment
- **Docker**:
  ```bash
  docker build -t todo-frontend .
  docker run -p 3000:3000 -e BACKEND_URL=https://your-api.com todo-frontend
  ```

## Repository Independence
This repository is completely separate from the backend repository. It communicates with the backend exclusively via HTTP calls to the `BACKEND_URL`.
