🔌 Streamlit Supabase Connector

A Streamlit connection component to connect Streamlit to Supabase Storage, Database, and Auth.

🧑‍🎓 Interactive tutorial

🤔 Why use this?

• Cache functionality to cache returned results. Save time and money on your API requests
• Same method names as the Supabase Python API. Minimum relearning required
• Exposes more storage methods than currently supported by the Supabase Python API. For example, update(), create_signed_upload_url(), and upload_to_signed_url()
• Less keystrokes required when integrating with your Streamlit app.

Examples with and without the connector

Without connector	With connector
Download file to local system from Supabase storage
import mimetypes import streamlit as st from supabase import create_client supabase_client = create_client( supabase_url="...", supabase_key="..." ) bucket_id = st.text_input("Enter the bucket_id") source_path = st.text_input("Enter source path") file_name = source_path.split("/")[-1] if st.button("Request download"): with open(file_name, "wb+") as f: response = supabase_client.storage.from_( bucket_id ).download(source_path) f.write(response) mime = mimetypes.guess_type(file_name)[0] data = open(file_name, "rb") st.download_button( "Download file", data=data, file_name=file_name, mime=mime, )	import streamlit as st from st_supabase_connection import SupabaseConnection st_supabase_client = st.connection( name="supabase_connection", type=SupabaseConnection ) bucket_id = st.text_input("Enter the bucket_id") source_path = st.text_input("Enter source path") if st.button("Request download"): file_name, mime, data = st_supabase_client.download( bucket_id, source_path, ) st.download_button( "Download file", data=data, file_name=file_name, mime=mime, )
Upload file from local system to Supabase storage
import streamlit as st from supabase import create_client supabase_client = create_client( supabase_key="...", supabase_url="..." ) bucket_id = st.text_input("Enter the bucket_id") uploaded_file = st.file_uploader("Choose a file") destination_path = st.text_input("Enter destination path") overwrite = "true" if st.checkbox("Overwrite?") else "false" with open(uploaded_file.name, "wb") as f: f.write(uploaded_file.getbuffer()) if st.button("Upload"): with open(uploaded_file.name, "rb") as f: supabase_client.storage.from_(bucket_id).upload( path=destination_path, file=f, file_options={ "content-type": uploaded_file.type, "x-upsert": overwrite, }, )	import streamlit as st from st_supabase_connection import SupabaseConnection st_supabase_client = st.connection( name="supabase_connection", type=SupabaseConnection ) bucket_id = st.text_input("Enter the bucket_id") uploaded_file = st.file_uploader("Choose a file"): destination_path = st.text_input("Enter destination path") overwrite = "true" if st.checkbox("Overwrite?") else "false" if st.button("Upload"): st_supabase_client.upload( bucket_id, "local", uploaded_file, destination_path, overwrite, )

🛠️ Setup

1. Install st-supabase-connection

pip install st-supabase-connection

2. Set the SUPABASE_URL and SUPABASE_KEY Streamlit secrets as described here.

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().

🪄 Usage

1. Import

from st_supabase_connection import SupabaseConnection

2. Initialize

st_supabase_client = st.connection(
    name="YOUR_CONNECTION_NAME",
    type=SupabaseConnection,
    ttl=None,
    url="YOUR_SUPABASE_URL", # not needed if provided as a streamlit secret
    key="YOUR_SUPABASE_KEY", # not needed if provided as a streamlit secret
)

3. Use in your app to query tables and files. Happy Streamlit-ing! 🎈
