- Latest Litestar configured with best practices
- Integration with SQLAlchemy 2.0, SAQ (Simple Asynchronous Queue), and Structlog
- Extends built-in Litestar click CLI
- Frontend integrated with ViteJS and includes Jinja2 templates that integrate with Vite websocket/HMR support
- Multi-stage Docker build using a minimal Python 3.11 runtime image.
- Pre-configured user model that includes teams and associated team roles
- Examples of using guards for superuser and team-based auth.
- Examples using raw SQL for more complex queries
Take what you need and adapt it to your own projects

To run the application through Uvicorn using the standard Litestar CLI, you can use the following:
❯ app run --help
Using Litestar app from env: 'app.asgi:create_app'
Usage: app run [OPTIONS]
Run a Litestar app.
The app can be either passed as a module path in the form of <module
name>.<submodule>:<app instance or factory>, set as an environment variable
LITESTAR_APP with the same format or automatically discovered from one of
these canonical paths: app.py, asgi.py, application.py or app/__init__.py.
When auto-discovering application factories, functions with the name
``create_app`` are considered, or functions that are annotated as returning a
``Litestar`` instance.
