Backend for the Drag And Drop Card — a Home Assistant integration that securely stores and serves drag‑and‑drop card configurations.

Repo: Prosono/Drag-And-Drop-Card-Backend • License: MIT • Language: Python

• Persists UI configurations for the companion Drag And Drop Card.
• Exposes a simple backend inside Home Assistant so the card can save, load, and delete its layouts/configs.
• Uses Home Assistant’s standards (config entries, services, storage helpers) so everything lives neatly within your HA setup.

1. In Home Assistant, open HACS → Integrations → 3‑dot menu → Custom repositories.
2. Add the repository: https://github.com/Prosono/Drag-And-Drop-Card-Backend as type Integration.
3. Find Drag-And-Drop-Card Backend in HACS and click Download.
4. Go into "Settings" then "Devices and Services" And Click "Add Integration"
5. Search for "Drag And Drop Card Backend" and select it.
6. Restart Home Assistant after the installation is complete.

1. Copy the folder custom_components/drag_and_drop_card_backend from this repo into your Home Assistant config directory at: config/custom_components/drag_and_drop_card_backend/.
2. Restart Home Assistant.

Your HA config directory is typically ~/.homeassistant or /config (if using HA OS / Supervised).

The backend is designed to be used by the front-end Drag And Drop Card. Typical flows:

• Save a layout from the card → backend persists it.
• Load a layout on dashboard render → backend returns it.
• Delete a layout → backend removes it.

The integration is designed so that you do not have to do any manual operations for saving / retreiving saved dashboards.

File list may vary by release, but the integration follows standard HA component conventions.

1. Create a Home Assistant dev instance (e.g., with HA Container or a test HA OS VM).
2. Mount/link the component to /config/custom_components/drag_and_drop_card_backend.
3. Enable Advanced Mode in your HA user profile for extra dev tools.
4. Watch the Logs (Settings → System → Logs) while reloading the integration.

• Follow semantic versioning.
• Use GitHub Releases and update manifest.json version accordingly.

Where are layouts stored?
Inside Home Assistant’s storage (e.g., .storage), handled by the integration. You normally don’t need to manage these files manually.

Can I back up the data?
Yes — use HA’s built-in Backups (Snapshots) to capture everything.

Do I need the front-end card?
This backend is meant to be paired with the Drag And Drop Card. On its own, it won’t render UI — it just stores and serves configs.

• Data is stored locally within your Home Assistant instance.
• No cloud sync is performed by the backend unless you add it yourself via HA add-ons or external automations.
