supabase 2.0.0

Supabase client for Python.

supabase-py

Supabase client for Python. This mirrors the design of supabase-js

Status	Stability	Goal
✅	Alpha	We are testing Supabase with a closed set of customers
✅	Public Alpha	Anyone can sign up over at app.supabase.io. But go easy on us, there are a few kinks.
🚧	Public Beta	Stable enough for most non-enterprise use-cases
❌	Public	Production-ready

We are currently in Public Alpha. Watch "releases" of this repo to get notified of major updates.

Installation

Recomended: First activate your virtual environment, with your favourite system. For example, we like poetry and conda!

PyPi installation

Now install the package. (for > Python 3.7)

# with pip
pip install supabase

# with conda
conda install -c conda-forge supabase

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

It's usually best practice to set your api key environment variables in some way that version control doesn't track them, e.g don't put them in your python modules! Set the key and url for the supabase instance in the shell, or better yet, use a dotenv file. Heres how to set the variables in the shell.

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

We can then read the keys in the python source code.

import os
from supabase import create_client, Client

url: str = os.environ.get("SUPABASE_URL")
key: str = os.environ.get("SUPABASE_KEY")
supabase: Client = create_client(url, key)

Use the supabase client to interface with your database.

Running Tests

Currently the test suites are in a state of flux. We are expanding our clients tests to ensure things are working, and for now can connect to this test instance, that is populated with the following table:

The above test database is a blank supabase instance that has populated the countries table with the built in countries script that can be found in the supabase UI. You can launch the test scripts and point to the above test database by running

./test.sh

See issues for what to work on

Rough 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 Gotrue-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
• 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)
