Trong lần khảo sát cuối cùng dành cho các lập trình viên Python, đã rõ ràng <a href="https://www.jetbrains.com/research/python-developers-survey-2017/#tools-and-features" class="external-link" target="_blank">rằng đa số các lập trình viên sử dụng tính năng "autocompletion"</a>.

But at some point, there was no other option than creating something that provided all these features, taking the best ideas from previous tools, and combining them in the best way possible, using language features that weren't even available before (Python 3.6+ type hints).

## Previous tools

The hierarchy is like:

* **Uvicorn**: an ASGI server
    * **Starlette**: (uses Uvicorn) a web microframework
        * **FastAPI**: (uses Starlette) an API microframework with several additional features for building APIs, with data validation, etc.

* **Uvicorn**:

* <a href="https://pgjones.gitlab.io/hypercorn/" class="external-link" target="_blank">Hypercorn</a>: an ASGI server compatible with HTTP/2 and Trio among other features.
* <a href="https://github.com/django/daphne" class="external-link" target="_blank">Daphne</a>: the ASGI server built for Django Channels.

## Server Machine and Server Program

## Client and SDK Generators - Sponsor

There are also some **company-backed** Client and SDK generators based on OpenAPI (FastAPI), in some cases they can offer you **additional features** on top of high-quality generated SDKs/clients.

### エディタのサポート

すべてのフレームワークは使いやすく直感的に使用できるように設計されており、すべての決定は開発を開始する前でも複数のエディターでテストされ、最高の開発体験が保証されます。

前回のPython開発者調査では、<a href="https://www.jetbrains.com/research/python-developers-survey-2017/#tools-and-features" class="external-link" target="_blank">最も使用されている機能が「オートコンプリート」であることが明らかになりました。</a>

**FastAPI** フレームワークは、この要求を満たすことを基本としています。オートコンプリートはどこでも機能します。

ドキュメントに戻る必要はほとんどありません。

エディターがどのように役立つかを以下に示します:

## 0.75.0

### Features

* ✨ Add support for custom `generate_unique_id_function` and docs for generating clients. New docs: [Advanced - Generate Clients](https://fastapi.tiangolo.com/advanced/generate-clients/). PR [#4650](https://github.com/tiangolo/fastapi/pull/4650) by [@tiangolo](https://github.com/tiangolo).

## 0.74.1

### Features

!!! tip
    This tutorial previously used <a href="https://pyjwt.readthedocs.io/" class="external-link" target="_blank">PyJWT</a>.

    But it was updated to use Python-jose instead as it provides all the features from PyJWT plus some extras that you might need later when building integrations with other tools.

## Password hashing

We, as humans, make **mistakes**, all the time. Software almost *always* has **bugs** hidden in different places. 🐛

And we as developers keep improving the code as we find those bugs and as we implement new features (possibly adding new bugs too 😅).

### Small Errors Automatically Handled

!!! check
    The `prefix`, `tags`, `responses`, and `dependencies` parameters are (as in many other cases) just a feature from **FastAPI** to help you avoid code duplication.

### Import the dependencies

This code lives in the module `app.routers.items`, the file `app/routers/items.py`.
