Step-by-Step Guide to Building Full Stack FastAPI Apps 10x Faster with Supabase

Supabase is an open-source Firebase alternative that allows you to rapidly build full-stack applications. In this tutorial, we will walk you through the process of building a Full Stack FastAPI application using Supabase, which will enable you to develop applications up to 10x faster than traditional methods.

Step 1: Set up your Supabase account
To get started, you will need to create a Supabase account. Go to https://app.supabase.io/ and sign up for a free account. Once you have created your account, you will be able to access your Supabase dashboard, where you can create a new project.

Step 2: Create a new Supabase project
In your Supabase dashboard, click on the "New Project" button and give your project a name. Once you have created your project, you will be provided with an API url and an API key, which you will need to access the Supabase API from your FastAPI application.

Step 3: Set up your FastAPI project
Next, you will need to set up a new FastAPI project. You can do this by following the instructions in the FastAPI documentation: https://fastapi.tiangolo.com/tutorial/. Once you have set up your FastAPI project, you can start integrating it with Supabase.

Step 4: Install the required dependencies
To integrate Supabase with your FastAPI project, you will need to install the following dependencies:

• supabase-py: This is the Python client library for the Supabase API.
• pydantic: This library will help you define your data models and schemas in your FastAPI application.

You can install these dependencies using pip:

pip install supabase-py pydantic

Step 5: Define your data models
Before you can start interacting with Supabase from your FastAPI application, you will need to define your data models using pydantic. These models will represent the tables in your Supabase database. Here is an example of a simple data model for a "users" table:

from pydantic import BaseModel

class User(BaseModel):
    id: int
    name: str
    email: str

Step 6: Connect to your Supabase database
To connect to your Supabase database from your FastAPI application, you will need to use the Supabase Python client. You can create a new client instance by passing in your Supabase API url and API key:

import os
from supabase_py import create_client

SUPABASE_URL = os.getenv("SUPABASE_URL")
SUPABASE_KEY = os.getenv("SUPABASE_KEY")

supabase = create_client(SUPABASE_URL, SUPABASE_KEY)

Step 7: Create API endpoints
Now that you have connected to your Supabase database, you can start creating API endpoints in your FastAPI application to interact with your data. For example, you can create a GET endpoint to fetch all users from the "users" table:

@app.get("/users")
def get_users():
    users = supabase.table("users").select("*").execute()
    return users["data"]

Step 8: Test your endpoints
To test your API endpoints, you can use a tool like Postman to send requests to your FastAPI application. Make sure to send a GET request to the /users endpoint to fetch all users from the "users" table in your Supabase database.

Step 9: Deploy your application
Once you have tested your API endpoints locally, you can deploy your FastAPI application to a production environment. You can use platforms like Heroku, AWS, or Google Cloud Platform to host your application.

Step 10: Monitor and maintain your application
After deploying your application, it is important to monitor its performance and ensure that it is running smoothly. You can use tools like Prometheus and Grafana to monitor the performance of your application and react to any issues that may arise.

By following this tutorial, you should now have a Full Stack FastAPI application integrated with Supabase, allowing you to build applications up to 10x faster than traditional methods. Good luck with your development!
