backend-dash 0.1.0

Scaffold a FastAPI + SQLAlchemy backend with SQLite/Postgres/MySQL and optional JWT + Google OAuth auth

backend-dash

A CLI that generates ready-to-code FastAPI backend projects with SQLAlchemy, SQLite, PostgreSQL, MySQL, Alembic migrations, CRUD examples, tests, and optional JWT + Google OAuth authentication.

Features

• Scaffold a complete FastAPI backend in seconds.
• Supports --db=sqlite|postgres|mysql with SQLite as the default.
• Generates a working SQLAlchemy setup and DB session wiring.
• Adds an example CRUD resource so you can start from real code, not boilerplate.
• Includes tests for the generated project.
• Adds Alembic migrations for PostgreSQL and MySQL.
• Keeps SQLite simple with create_all for zero-config local development.
• Optional --auth mode adds JWT + Google OAuth auth support.
• Clear validation for unsupported database values.
• Clean .env.example setup for local development and migrations.

Installation

One-off usage

uvx backend-dash init "My API"

Install locally

pip install backend-dash
backend-dash init "My API"

Editable install for development

git clone https://github.com/prathamdmehta/backend-dash.git
cd backend-dash
pip install -e . --break-system-packages

Usage

Create a new project:

backend-dash init "Demo Project"

Create a project with auth:

backend-dash init "Demo Project Auth" --auth

Choose a database:

backend-dash init "My API" --db=sqlite
backend-dash init "My API" --db=postgres
backend-dash init "My API" --db=mysql

Combine database and auth:

backend-dash init "My API" --db=postgres --auth

What gets generated

Base project

• FastAPI app structure.
• SQLAlchemy session and base model wiring.
• Example item resource with CRUD routes.
• Pydantic schemas and models.
• Pytest test setup.

With --auth

• Repository layer with a generic BaseRepository and UserRepository.
• Auth service for registration, login, JWT issuance, and Google token exchange.
• Validation with proper schema constraints.
• Centralized error handling with a consistent error response shape.
• Auth routes for register, login, me, Google login, and Google callback.

Database support

SQLite

SQLite is the default and uses create_all for a simple local setup.

PostgreSQL

For PostgreSQL, the scaffold uses Alembic migrations and real schema management.

MySQL

For MySQL, the scaffold also uses Alembic migrations and the correct MySQL driver setup.

Migrations

For PostgreSQL and MySQL, the project generates Alembic configuration and an env.py wired to DATABASE_URL and your app metadata.

Typical workflow:

alembic revision --autogenerate -m "create initial tables"
alembic upgrade head

The generated .env.example includes the right migration flow so you can move from scaffold to production-style schema management quickly.

Project structure

my_api/
├── app/
├── tests/
├── alembic/
├── alembic.ini
└── .env.example

If --auth is enabled, additional auth-related modules are included inside the app structure.

Example

Generate a new API project:

backend-dash init "Orders API" --db=postgres --auth

This creates a FastAPI backend with database wiring, migrations, tests, and authentication already in place, so you can start on business logic immediately.

Development

git clone https://github.com/prathamdmehta/backend-dash.git
cd backend-dash
pip install -e . --break-system-packages

Then run the CLI locally:

backend-dash init "Demo Project"
