Background

大部分的框架，要么只支持 restful API， 要么只支持CLI。

例如：

fastapi 或者 django_rest_framework  支持rest API

click 支持将函数装饰为 CLI

特殊情况，需要两种都要支持。即一份代码， 同时支持两种接口。

hug就是为此而生。

https://github.com/hugapi/hug

号称未来的API, 代码一次书写，不管何种客户端使用， 都可以支持。支持 本地调用， HTTP调用 ， CLI调用。

Embrace the APIs of the future

Drastically simplify API development over multiple interfaces. With hug, design and develop your API once, then expose it however your clients need to consume it. Be it locally, over HTTP, or through the command line - hug is the fastest and most modern way to create APIs on Python3.

设计目标：

根据代码自动产生文档

运行快 -- 基于falcon restapi框架

测试非常友好

提用户包装好各种接口类型

面向未来

hug‘s Design Objectives:

• Make developing a Python driven API as succinct as a written definition.
• The framework should encourage code that self-documents.
• It should be fast. A developer should never feel the need to look somewhere else for performance reasons.
• Writing tests for APIs written on-top of hug should be easy and intuitive.
• Magic done once, in an API framework, is better than pushing the problem set to the user of the API framework.
• Be the basis for next generation Python APIs, embracing the latest technology.
