## 🚀 Quickstart

1. Install the connector and its dependencies.

    ```bash
    pip install st-supabase-connection
    ```

2. Provide your Supabase credentials. In Streamlit Cloud, add them to `secrets.toml`:

    ```toml
    [connections.supabase_connection]
    url = "https://your-project.supabase.co"
    key = "service_role_or_anon_key"
    ```

    For local development you can use environment variables (`SUPABASE_URL`, `SUPABASE_KEY`) or pass the values directly during connection creation.

3. Create the cached connection in your app.

    ```python
    import streamlit as st
    from st_supabase_connection import SupabaseConnection

    st_supabase = st.connection(
        name="supabase_connection",
        type=SupabaseConnection,
        ttl=None,  # cache indefinitely; override when you need fresher data
    )

    # Example: list buckets without re-authenticating on every rerun
    buckets = st_supabase.list_buckets()
    st.write(buckets)
    ```

## :thinking: Why use this?

- [x] Cache functionality to cache returned results. **Save time and money** on your API requests
- [x] Same method names as the Supabase Python API. **Minimum relearning required**
- [x] **Exposes more storage methods** than currently supported by the Supabase Python API. For example, `update()`, `create_signed_upload_url()`, and `upload_to_signed_url()`
- [x] Handles common Supabase quirks—leading slashes are normalised, MIME types inferred, and downloads streamed in memory—so you spend less time on glue code.
- [x] **Less keystrokes required** when integrating with your Streamlit app.

## :hammer_and_wrench: Setup

1. Install `st-supabase-connection`

```sh
pip install st-supabase-connection
```

2. Set the `SUPABASE_URL` and `SUPABASE_KEY` Streamlit secrets as described [here](https://docs.streamlit.io/streamlit-community-cloud/get-started/deploy-an-app/connect-to-data-sources/secrets-management).

> [!NOTE]  
> For local development outside Streamlit, you can also set these as your environment variables (recommended), or pass these to the `url` and `key` args of `st.connection()`.

## :magic_wand: Usage

1. Import

```python
from st_supabase_connection import SupabaseConnection, execute_query
```

2. Initialize

```python
st_supabase_client = st.connection(
    name="YOUR_CONNECTION_NAME",
    type=SupabaseConnection,
    ttl=None,
)
```

3. Use the connection to work with Storage, Database, and Auth in a cached, Streamlit-friendly way:

    ```python
    # Storage
    file_name, mime, data = st_supabase.download("bucket", "path/to/report.csv", ttl=300)

    # Database (leverages postgrest-py under the hood)
    from st_supabase_connection import execute_query
    users = execute_query(
        st_supabase.table("users").select("name, email").order("created_at", desc=True),
        ttl="15m",
    )

    # Auth (cached helper)
    st_supabase.cached_sign_in_with_password({"email": email, "password": password})
    ```

#### Create new user

```python
st_supabase_client.auth.sign_up(
    dict(
        email='test.user@abc.com',
        password='***',
        options=dict(
            data=dict(
                fname='Siddhant',
                attribution='I made it :)',
            )
        )
    )
)
```

#### Sign in with password

`SupabaseConnection()` offers a cached version of `sign_in_with_password()` for faster, request-free sign-ins.

```python
st_supabase_client.cached_sign_in_with_password(dict(email='test.user@abc.com', password='***'))
```

#### Retrieve session

```python
st_supabase_client.auth.get_session()
```

#### Retrieve user

```python
st_supabase_client.auth.get_user()
```

#### Sign out

```python
st_supabase_client.auth.sign_out()
```
