pait

Pait is an api tool that can be used in any python web framework, the features provided are as follows:

• Parameter checksum automatic conversion (parameter check depends on Pydantic)
• Parameter dependency verification
• Automatically generate openapi files
• Swagger, Redoc, Rapidoc, Elements, OpenAPI route
• gRPC Gateway route
• TestClient support, support response result verification
• Support for plugin extensions, such as the Mock plugin, CheckResponse Plugin, Cache Response Plugin
• WebSocket support
• Auto API Test support

Note:

• mypy check 100%

• python version >= 3.7 (support postponed annotations)

Installation

pip install pait --pre

If want to use the gRPC gateway feature, need to add a 'grpc' dependency:

pip install pait[grpc] --pre

Simple Example

from typing import Type
import uvicorn  # type: ignore
from starlette.applications import Starlette
from starlette.responses import JSONResponse
from starlette.routing import Route

from pait.app.starlette import pait
from pait.field import Body
from pait.openapi.doc_route import add_doc_route
from pait.model.response import JsonResponseModel
from pydantic import BaseModel, Field


class DemoResponseModel(JsonResponseModel):
    """demo post api response model"""
    class ResponseModel(BaseModel):
        uid: int = Field()
        user_name: str = Field()

    description: str = "demo response"
    response_data: Type[BaseModel] = ResponseModel


@pait(response_model_list=[DemoResponseModel])
async def demo_post(
    uid: int = Body.i(description="user id", gt=10, lt=1000),
    user_name: str = Body.i(description="user name", min_length=2, max_length=4)
) -> JSONResponse:
    return JSONResponse({'uid': uid, 'user_name': user_name})


app = Starlette(routes=[Route('/api', demo_post, methods=['POST'])])
add_doc_route(app)
uvicorn.run(app)

Support Web framework

Framework	Description
Flask	All features supported
Sanic	All features supported
Starlette	All features supported
Tornado	All features supported
Django	Coming soon

If the web framework is not supported(which you are using).

Can be modified sync web framework according to pait.app.flask

Can be modified async web framework according to pait.app.starlette

Performance

For the parameter validation and transformation feature, Pait is mainly responsible for injecting the request data dependency into the Pydantic model, and then the Pydanitc verifies and transforms the data.

The time consumed by this process <=0.0003 (s), for benchmarks data and subsequent optimization, see #27
