supabase-py-async 2.4.2

supabase-py with async synax

supabase-py-async

async-part of supabase-py Python client for Supabase-py

• Documentation: supabase.com/docs
• Usage:
  • Supabase with Python ⚡fastapi⚡ app
  • GitHub OAuth in your Python Flask app
  • Python data loading with Supabase

Installation

We recommend activating your virtual environment. For example, we like poetry and conda!

PyPi installation

Install the package (for > Python 3.9):

# with pip
pip install supabase-py-async
# with poetry (recommended)
poetry add supabase-py-async

Local installation

You can also install locally after cloning this repo. Install Development mode with pip install -e, which makes it so when you edit the source code the changes will be reflected in your python module.

Usage

Set your Supabase environment variables in a dotenv file, or using the shell:

export SUPABASE_URL="my-url-to-my-awesome-supabase-instance"
export SUPABASE_KEY="my-supa-dupa-secret-supabase-api-key"

init the client in fastapi lifespan event

import os
from contextlib import asynccontextmanager
from dotenv import load_dotenv
from fastapi import FastAPI
from supabase_py_async import create_client
from supabase_py_async.lib.client_options import ClientOptions
client = None
@asynccontextmanager
async def lifespan(app: FastAPI):
    """ life span events"""
    identify_worker = None
    try:
        # start client
        load_dotenv()
        url: str = os.getenv("SUPABASE_URL")
        key: str = os.getenv("SUPABASE_KEY")
        client = await create_client(url, key, options=ClientOptions(
            postgrest_client_timeout=10, storage_client_timeout=10))
        yield
    finally:
        pass

Use the supabase client to interface with your database.

async def list_files():
    """ list files """
    # List all files in Storage.

    data = await client.storage.from_(bucket_name).move(old_file_path, new_file_path)

Roadmap

• Wrap Postgrest-py
  • Add remaining filters
  • Add support for EXPLAIN
  • Add proper error handling
• Wrap Realtime-py
  • Integrate with Supabase-py
  • Support WALRUS
  • Support broadcast (to check if already supported)
• Wrap auth-py
  • Remove references to GoTrue-js v1 and do a proper release
  • Test and document common flows (e.g. sign in with OAuth, sign in with OTP)
  • Add MFA methods and SSO methods
  • Add Proof Key for Code Exchange (PKCE) methods. Unlike the JS library, we do not currently plan to support Magic Link (PKCE). Please use the token hash in tandem with verifyOTP instead.
• Wrap storage-py
  • Support resumable uploads
  • Setup testing environment
  • Document how to properly upload different file types (e.g. jpeg/png and download it)
• Wrap functions-py

Overall Tasks:

• Add async support across the entire library
• Add FastAPI helper library (external to supabase-py)
• Add django-supabase-postgrest (external to supabase-py)
