Warning
Please note that this project is currently in a pre-release stage of development. This means the library is still under active development and some things may not be functional. We encourage developers to experiment with this project and provide feedback`
This is a reference application that you can use to get your next Litestar application running quickly.
It contains most of the boilerplate required for a production web API with features like:
- Latest Litestar configured with best practices
- Integration with SQLAlchemy 2.0, SAQ (Simple Asynchronous Queue), Structlog, and Granian
- Extends built-in Litestar click CLI
- Frontend integrated with React, InertiaJS, Vite and includes Jinja2 templates that integrate with Vite websocket/HMR support
- Multi-stage Docker build using a minimal Python 3.12 runtime image.
- Optional Multi-stage Distroless Docker build.
- Pre-configured user model that includes teams and associated team roles
- Examples of using guards for superuser and team-based auth.
- OpenTelemetry & Logfire Integration
- Google & GitHub SSO integration
Take what you need and adapt it to your own projects
To quickly get a development environment running, run the following:
make install
. .venv/bin/activatecp .env.local.example .env
pdm run start-infra # this starts a database and redis instance only
# this will start the SAQ worker, Vite development process, and Litestar
pdm run app run
# to stop the database and redis, run
pdm run stop-infradocker compose upWe have documented the process to help you get the repository up and running. Check out the documentation for more information.

To run the application through Granian (HTTP1 or HTTP2) using the standard Litestar CLI, you can use the following:
❯ app run --help
Using Litestar app from env: 'app.asgi:app'
Loading environment configuration from .env
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.
