Add a Public Endpoint to Display API State Using Jinja2 Templates

[0x1026]

The microservice will include a public endpoint to display the current state of the sensors through a web page. This web page will use Jinja2 templates to render sensor data in an organized and user-friendly format. The microservice will serve this page directly, using FastAPI to handle the backend logic and template rendering.

Tasks

• Design the Screen Layout
  • Plan the structure of the web page to display:
    • Sensor names or IDs.
    • Current sensor states (e.g., active/inactive, temperature, or other metrics).
    • Additional metadata or information, if required.
• Add the Public Endpoint
  • Implement an endpoint in the microservice (e.g., /sensors) to serve the web page.
  • Ensure the endpoint is accessible and handles requests efficiently.
• Fetch Data from the API
  • Use the microservice to retrieve and process sensor data for the template.
  • Handle errors gracefully if the API fails or returns incomplete data.
• Implement Jinja2 Template
  • Create a responsive and visually appealing template to display sensor data.
  • Include elements like tables, charts, or status indicators to improve data visualization.
  • Add error messages or loading indicators for better user experience.
• Integrate with Backend Logic
  • Query the sensor API, process the response, and pass the data to the Jinja2 template for rendering.
  • Optimize performance for real-time data updates, if applicable.
• Test the Endpoint and Screen
  • Verify the endpoint serves the page correctly under various conditions:
    • Normal operation with all sensors online.
    • Scenarios where sensors are offline or returning errors.
    • Cases where the API itself is unavailable.
  • Test the screen’s responsiveness on different devices and browsers.

Considerations

• Ensure the endpoint and page comply with best practices for security and performance.
• Use responsive design principles to make the page accessible across devices.
• Provide visual indicators for sensor states (e.g., green for active, red for inactive).
• Document the endpoint and its purpose for future maintainability.
