Easily generate a template for your Fastapi applications, complete with JWT authentication and Google sign-in

Fast Template

Easily generate a template for your FastAPI applications, complete with JWT authentication and Google sign-in.

Installation

You can install Fast Template via pip:

pip install fast-template-python

Or using poetry:

poetry add fast-template-python

Usage

To initialize a project in an existing folder:

fast-template init project_name .

To create a new project:

fast-template init project_name

Once the template is set up, you'll need to create a .env file as required by the settings.py file (feel free to modify it to suit your needs). An example of a .env is:

POSTGRES_URL = postgresql+asyncpg://postgres@localhost/your_db_name

ACCESS_TOKEN_SECRET = Your-Access-Token-Secret
REFRESH_TOKEN_SECRET = Your-Refresh-Token-Secret
RESET_PASSWORD_SECRET = Your-Reset-Password-Secret

SECRET_KEY = Your-Secret-Key

JWT_ALGORITHM = HS256

MAIL_USERNAME = [e-mail]
MAIL_FROM_NAME = Your-Name
MAIL_PASSWORD = yourmailpassword
MAIL_FROM = [e-mail]
MAIL_PORT = 000 # 587 for gmail
MAIL_SERVER = your_mail_server # smtp.gmail.com for gmail

REDIS_HOST = localhost
REDIS_PORT = 6379

GOOGLE_CLIENT_ID = YOUR_GOOGLE_CLIENT_ID
GOOGLE_CLIENT_SECRET = YOUR_GOOGLE_CLIENT_SECRET
GOOGLE_REDIRECT_URI = https://yourdomain.com/auth/google/callback

Migrations

You can set up database migrations using Alembic:

alembic init —template async migrations

For more information on using Alembic, check the official tutorial.

Features

Authentication

• JWT-based authentication is built-in.
• Google sign-in is fully integrated, right down to the database layer.

Extensible Folder Structure

The folder structure is designed to be modular and scalable, inspired by Philip Okiokio (LinkedIn, GitHub). It promotes loose coupling and clean separation of concerns.

Each operation is handled by three main layers:

1. Router Layer: Defines FastAPI routes.
2. Service Layer: Contains the business logic.
3. Database Layer: Manages database interactions.

The data flow is structured as follows:

Router Layer → Service Layer → Database Layer

The service layer handles the data exchange between the router and the database, while the router serializes requests and passes them to the service.

The folder structure on running

fast-template init totrac

is

Pre-configured Services

The root folder contains core services required for the backend, including:

1. Database setup
2. Redis caching
3. Email templates
4. Background workers (using ARQ)
5. Logging configuration
6. Application settings

Schema and Database Layers

• Schema: Pydantic models for serialization/deserialization, organized by feature (e.g., authentication schemas are in the auth folder).
• Database: Handlers and ORM integration using SQLAlchemy.

Work in Progress

This package is a work in progress, created to streamline the setup of backend projects.
