• 👉 Full async (ASGI) support
• 👉 Layered dependency injection
• 👉 OpenAPI 3.1 schema generation with Redoc UI
• 👉 Route guards based authorization
• 👉 Simple middleware and authentication
• 👉 Support for pydantic models and pydantic dataclasses
• 👉 Support for standard library dataclasses
• 👉 Support for SQLAlchemy declarative classes
• 👉 Plugin system to allow extending supported classes
• 👉 Ultra-fast json serialization and deserialization using orjson

Installation

Using your package manager of choice:

pip install starlite

OR

poetry add starlite

OR

pipenv install starlite

Minimal Example

Define your data model using pydantic or any library based on it (see for example ormar, beanie, SQLModel etc.):

from pydantic import BaseModel, UUID4


class User(BaseModel):
    first_name: str
    last_name: str
    id: UUID4

You can alternatively use a dataclass, either the standard library one or the one from pydantic:

from uuid import UUID

# from pydantic.dataclasses import dataclass
from dataclasses import dataclass

@dataclass
class User:
    first_name: str
    last_name: str
    id: UUID

Define a Controller for your data model:

from typing import List

from pydantic import UUID4
from starlite import Controller, Partial, get, post, put, patch, delete

from my_app.models import User


class UserController(Controller):
    path = "/users"

    @post()
    async def create_user(self, data: User) -> User:
        ...

    @get()
    async def list_users(self) -> List[User]:
        ...

    @patch(path="/{user_id:uuid}")
    async def partially_update_user(self, user_id: UUID4, data: Partial[User]) -> User:
        ...

    @put(path="/{user_id:uuid}")
    async def update_user(self, user_id: UUID4, data: User]) -> User]:
        ...

    @get(path="/{user_id:uuid}")
    async def get_user(self, user_id: UUID4) -> User:
        ...

    @delete(path="/{user_id:uuid}")
    async def delete_user(self, user_id: UUID4) -> User:
        ...

Import your controller into your application's entry-point and pass it to Starlite when instantiating your app:

from starlite import Starlite

from my_app.controllers.user import UserController

app = Starlite(route_handlers=[UserController])

To run your application, use an ASGI server such as uvicorn:

uvicorn my_app.main:app --reload
