BáiZé

Powerful and exquisite WSGI/ASGI framework/toolkit. Only relies on the standard library.

The minimize implementation of methods required in the Web framework. No redundant implementation means that you can freely customize functions without considering the conflict with baize’s own implementation.

Under the ASGI/WSGI protocol, the interface of the request object and the response object is almost the same, only need to add or delete await in the appropriate place. In addition, it should be noted that ASGI supports WebSocket but WSGI does not.

• Type annotations as strict as possible (almost no Any)
• Support range file response, server-sent event response
• Support WebSocket (only ASGI)
• WSGI, ASGI routing to combine any application like Django(wsgi)/Kuí(wsgi)/Pyramid/Bottle/Flask or Django(asgi)/Kuí(asgi)/Starlette/FastAPI/Sanic/Quart

Install

pip install -U baize

Quick Start

A short example for WSGI application, if you don’t know what is WSGI, please read PEP3333.

import time
from typing import Callable
from baize.wsgi import (
    decorator,
    request_response,
    Router,
    Request,
    Response,
    PlainTextResponse,
)
@decorator
def timer(request: Request, next_call: Callable[[Request], Response]) -> Response:
    start_time = time.time()
    response = next_call(request)
    end_time = time.time()
    response.headers["x-time"] = str(round((end_time - start_time) * 1000))
    return response
@request_response
@timer
def sayhi(request: Request) -> Response:
    return PlainTextResponse("hi, " + request.path_params["name"])
@request_response
@timer
def echo(request: Request) -> Response:
    return PlainTextResponse(request.body)
application = Router(
    ("/", PlainTextResponse("homepage")),
    ("/echo", echo),
    ("/sayhi/{name}", sayhi),
)
if __name__ == "__main__":
    import uvicorn
    uvicorn.run(application, interface="wsgi", port=8000)

A short example for ASGI application, if you don’t know what is ASGI, please read ASGI Documention.

import time
from typing import Awaitable, Callable
from baize.asgi import (
    decorator,
    request_response,
    Router,
    Request,
    Response,
    PlainTextResponse,
)
@decorator
async def timer(
    request: Request, next_call: Callable[[Request], Awaitable[Response]]
) -> Response:
    start_time = time.time()
    response = await next_call(request)
    end_time = time.time()
    response.headers["x-time"] = str(round((end_time - start_time) * 1000))
    return response
@request_response
@timer
async def sayhi(request: Request) -> Response:
    return PlainTextResponse("hi, " + request.path_params["name"])
@request_response
@timer
async def echo(request: Request) -> Response:
    return PlainTextResponse(await request.body)
application = Router(
    ("/", PlainTextResponse("homepage")),
    ("/echo", echo),
    ("/sayhi/{name}", sayhi),
)
if __name__ == "__main__":
    import uvicorn
    uvicorn.run(application, interface="asgi3", port=8000)
