How To Integrate FastAPI With Supabase

FastAPI is a modern, fast (high-performance), web framework for building APIs with Python 3.6+ based on standard Python type hints. Supabase is an open source Firebase alternative that provides a ready-to-use database, authentication, and storage solution. In this article, we will explore how to integrate FastAPI with Supabase to create a powerful and efficient API.

Step 1: Setting Up FastAPI

First, make sure you have FastAPI installed in your Python environment. You can install it using pip:


pip install fastapi


Next, create a new Python file for your FastAPI app. In this file, import FastAPI and create a FastAPI instance:


from fastapi import FastAPI

app = FastAPI()


Step 2: Setting Up Supabase

Sign up for a free account on Supabase and create a new project. Once you have created your project, you will be provided with a URL and an API key that you will use to access your Supabase database.

Step 3: Integrating FastAPI with Supabase

To integrate FastAPI with Supabase, you will need to use the HTTP client library to make requests to the Supabase API. Here is an example of how you can make a GET request to retrieve data from your Supabase database:


import httpx

async def fetch_data():
async with httpx.AsyncClient() as client:
response = await client.get(f"{url}/table_name", headers={'apikey': api_key})
data = response.json()
return data


Step 4: Building Your API Endpoints

Now that you have integrated FastAPI with Supabase, you can start building your API endpoints. You can define your API endpoints using FastAPI decorators like @app.get(), @app.post(), etc. Here is an example of how you can create a route that retrieves data from your Supabase database:


@app.get('/data')
async def get_data():
data = await fetch_data()
return data


Step 5: Testing Your API

You can now test your API by running your FastAPI app and making requests to your API endpoints. You can use tools like curl or Postman to send requests to your API and verify that it is working properly.

By integrating FastAPI with Supabase, you can create powerful and efficient APIs that leverage the capabilities of both frameworks. This allows you to build scalable and performant applications with ease.
