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), 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 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.

The above command will not start the background workers. Those can be launched separately in another terminal.
Alternately, the run-all command will automatically start the background workers in separate processes.

Commands to help you get this repository running.
Most of the development related tasks are included in the Makefile. To install an environment with all development packages run:
make installThis command does the following:
- install
pdmif it is not available in the path. - create a virtual environment with all dependencies configured
- build assets to be hosted by production asset server
There is a sample .env file located in the root of the repository.
cp .env.example .envNote SECRET_KEY, DATABASE_URI, and REDIS_URL are the most important config settings. Be sure to set this properly.
You can generate a SECRET_KEY by running:
❯ openssl rand -base64 32
+U9UcN0meCsxkShMINkqZ7pcwpEpOC9AwOArZI6mYDU=You can run most of the database commands with the integrated CLI tool.
To deploy migration to the database, execute:
❯ app database upgrade
