xpresso 0.1.2

A developer centric, performant Python web framework

Introduction

xpresso is an ASGI web framework built on top of Starlette, Pydantic and di, with heavy inspiration from FastAPI.

Some of the standout features are:

• ASGI support for high performance (within the context of Python web frameworks)
• OpenAPI documentation generation
• Automatic parsing and validation of request bodies and parameters, with hooks for custom extractors
• Full support for OpenAPI parameter serialization
• Highly typed and tested codebase with great IDE support
• A powerful dependency injection system, backed by di

Requirements

Python 3.7+

Installation

pip install xpresso

You'll also want to install an ASGI server, such as Uvicorn.

pip install uvicorn

Example

Create a file named example.py:

from pydantic import BaseModel
from xpresso import App, Path, FromPath, FromQuery

class Item(BaseModel):
    item_id: int
    name: str

async def read_item(item_id: FromPath[int], name: FromQuery[str]) -> Item:
    return Item(item_id=item_id, name=name)

app = App(
    routes=[
        Path(
            "/items/{item_id}",
            get=read_item,
        )
    ]
)

Run the application:

uvicorn example:app
