# Adding a Service to Heimdall Dashboard

After deploying a new self-hosted service, add it to the Heimdall dashboard for quick access.

## Database Location

Heimdall stores items in SQLite at:
```
/var/lib/docker/volumes/heimdall_config/_data/www/app.sqlite
```

The volume name may vary — check with `docker inspect heimdall`.

## Schema

```sql
items (
  id, title, colour, icon, url, description, pinned, "order",
  deleted_at, created_at, updated_at, type, user_id, class, appid, appdescription, role
)
```

Key columns for insertion:
- `title` — Display name
- `url` — Service URL
- `colour` — Hex colour (e.g., `"#d48c3c"`)
- `description` — Short description
- `type` — `"0"` for standard items
- `user_id` — Usually `1`
- `class` — For built-in app support: `App\\SupportedApps\\Plex\\Plex` (pattern: `App\\SupportedApps\\<Name>\\<Name>`). Use `None` for generic items.
- `appid` — `None` for generic items
- `pinned` — `0` (not pinned)
- `"order"` — Position in grid. Use `SELECT MAX("order") FROM items` + 1
- `icon` — `""` (empty string, uses built-in favicon fetching)

## Insert via Python

The DB is owned by root/Docker user. Access requires `sudo`:

```python
import sqlite3

db = "/var/lib/docker/volumes/heimdall_config/_data/www/app.sqlite"
conn = sqlite3.connect(db)

max_order = conn.execute('SELECT MAX("order") FROM items').fetchone()[0]

conn.execute("""
    INSERT INTO items (title, colour, icon, url, description, pinned, "order", type, user_id, class, appid)
    VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)
""", (
    "Audiobookshelf",
    "#d48c3c",
    "",
    "http://192.168.50.98:13378",
    "Audiobooks & podcasts",
    0,
    max_order + 1,
    "0",
    1,
    None,
    None
))
conn.commit()
conn.close()
```

## Pitfalls

- `sqlite3` CLI may not be installed on the host — use Python's `sqlite3` module instead
- "order" is a reserved word in SQLite — must be double-quoted in queries
- Items appear immediately in Heimdall — no restart needed
