Boards Backend

Backend for the Boards open-source creative toolkit for AI-generated content.

Features

• 🎨 Multi-provider support (Replicate, Fal.ai, OpenAI, etc.)
• 🔌 Pluggable architecture for generators and providers
• 📊 GraphQL API with Strawberry
• 🗄️ PostgreSQL with SQLAlchemy 2.0
• 🔄 Migrations with Alembic (async) and timestamped filenames
• 👥 Multi-tenant support with tenant isolation
• 🔐 Pluggable authentication (Supabase, Clerk, Auth0, JWT)
• 📦 Flexible storage backends (Local, S3, GCS, Supabase)

Installation

Minimal Install

The minimal installation includes core functionality with local filesystem storage only:

pip install weirdfingers-boards

Install with Specific Generators

Install only the generator providers you need:

# OpenAI generators (DALL-E 3, Whisper)
pip install weirdfingers-boards[generators-openai]

# Replicate generators (Flux Pro, Lipsync)
pip install weirdfingers-boards[generators-replicate]

# fal.ai generators (nano-banana)
pip install weirdfingers-boards[generators-fal]

# Multiple generators
pip install weirdfingers-boards[generators-openai,generators-replicate]

# All generators
pip install weirdfingers-boards[generators-all]

Install with Storage Backends

Add cloud storage providers as needed:

# S3 storage (AWS, MinIO, DigitalOcean Spaces)
pip install weirdfingers-boards[storage-s3]

# Supabase storage
pip install weirdfingers-boards[storage-supabase]

# Google Cloud Storage
pip install weirdfingers-boards[storage-gcs]

# All storage backends
pip install weirdfingers-boards[storage-all]

Full Installation

Install everything (all generators and storage backends):

pip install weirdfingers-boards[all]

Development Installation

For local development with all providers for type checking and testing:

# Clone the repository
git clone https://github.com/weirdfingers/boards.git
cd boards/packages/backend

# Install with dev dependencies (includes all providers)
uv sync

Configuration

Copy .env.example to .env and configure your settings:

cp .env.example .env

Key configuration options:

• BOARDS_DATABASE_URL: PostgreSQL connection string (e.g. postgresql://user:pass@localhost:5433/db)
• BOARDS_REDIS_URL: Redis connection for job queue
• BOARDS_STORAGE_PROVIDER: Storage backend (local, s3, gcs, supabase)
• BOARDS_AUTH_PROVIDER: Authentication provider

Database Setup

1. Create the database

createdb boards_dev

2. Apply initial schema via Alembic

# Use Alembic to create all tables
uv run alembic upgrade head

Development

Quick Start

# Start the API server (after installation and configuration)
boards-server

# Run database migrations
boards-migrate upgrade head

# Start background workers
boards-worker

Development Server

# Using uvicorn directly
uvicorn boards.api.app:app --reload --port 8088

# Or using the module
python -m boards.api.app

Access the GraphQL playground

Open http://localhost:8088/graphql in your browser.

Database migrations

When you need to change the database schema, use Alembic.

# Create a new migration (autogenerate from models in boards.dbmodels)
uv run alembic revision -m "add feature" --autogenerate

# Apply latest migrations
uv run alembic upgrade head

# Roll back one revision
uv run alembic downgrade -1

📖 For detailed migration workflow, see docs and examples under apps/docs.

Testing

Boards uses pytest for testing with both unit tests (mocked) and optional live API tests.

Running Tests

# Run all unit tests (excludes live API tests)
make test-backend

# Or using pytest directly
cd packages/backend
uv run pytest tests/

# Run with coverage
uv run pytest tests/ --cov=src/boards --cov-report=html

# Run specific test file
uv run pytest tests/generators/implementations/test_flux_pro.py -v

Unit Tests vs Live API Tests

Unit tests (default):

• Use mocked provider SDKs
• Fast and free
• Run automatically in CI/CD
• Located: tests/**/test_*.py

Live API tests (opt-in only):

• Make real API calls to providers
• Consume API credits
• Never run by default
• Located: tests/**/test_*_live.py

Running Live API Tests

Live tests verify real connectivity with provider APIs but cost money. They are excluded from default test runs.

# Set up API key
export BOARDS_GENERATOR_API_KEYS='{"REPLICATE_API_TOKEN": "r8_..."}'

# Run a specific generator's live test
uv run pytest tests/generators/implementations/test_flux_pro_live.py -v -m live_api

# Run all live tests for one provider
uv run pytest -m live_replicate -v

# Run all live tests (not recommended - expensive!)
uv run pytest -m live_api -v

For detailed information on live API testing, see:

• Live API Testing Guide
• Generator Testing Documentation
