Sensor Dashboard

This project implements a real-time sensor data dashboard using FastAPI for the backend and Server-Sent Events (SSE) to push data to a simple HTML frontend. The dashboard visualizes simulated sensor readings.

Features

• Real-time sensor data visualization.
• Backend built with FastAPI, providing a RESTful API and SSE endpoint.
• Frontend uses HTML, CSS (DaisyUI/TailwindCSS), and JavaScript to display dynamic charts.
• Automated testing with pytest.

Setup and Installation

Follow these steps to set up and run the project locally:

1. Navigate to the project directory:

   cd sensor-dashboard

2. Install dependencies using uv:

   If you don't have uv installed, you can install it via pip:

   pip install uv

   Then, install the project dependencies:

   uv pip install -r requirements.txt
   # (Note: If requirements.txt is not present, uv will install from pyproject.toml)

   Self-correction: The project uses pyproject.toml and uv.lock for dependency management. uv pip install without -r will install from pyproject.toml.

3. Run the application:

   uvicorn app:app --reload --port 8000

   The application will be accessible at http://127.0.0.1:8000.

Running Tests

To run the unit tests for the application, ensure you have pytest and httpx installed (they should be installed with the main dependencies if using uv):

uv run pytest test_app.py

This will execute the tests defined in test_app.py.
