# litestar-org/litestar

> Litestar is an ASGI framework for building APIs in Python. It provides data validation, dependency injection, ORM integration, authorization guards, middleware and a plugin API, so applications can be set up without assembling these parts separately. Route handlers are typed, and those type hints drive OpenAPI schema generation as well as validation and parsing of data.

## Install

From the README: https://github.com/litestar-org/litestar#installation

Install Litestar from PyPI.
    pip install litestar

Run the application with the litestar command.
    litestar run

## How it works

Requests enter a Litestar application object, which is built from route handlers as shown in the Quick Start example. litestar/__init__.py exposes the names used in the examples, such as Litestar and get, and litestar/app.py is one of the package's entry points. litestar/params.py is a central file for declaring handler parameters, and litestar/_kwargs/kwargs_model.py is a hotspot module in the _kwargs package that handles the keyword arguments passed to handlers. litestar/cli/main.py implements the litestar command that runs an application. The tests directory holds the unit tests and the docs directory holds the documentation sources.
