FastAPI 是一个用于构建 API 的现代、快速（高性能）的 web 框架，使用 Python 并基于标准的 Python 类型提示。

关键特性:

* **快速**：可与 **NodeJS** 和 **Go** 并肩的极高性能（归功于 Starlette 和 Pydantic）。[最快的 Python web 框架之一](#_11)。

* **高效编码**：提高功能开发速度约 200％ 至 300％。*
* **更少 bug**：减少约 40％ 的人为（开发者）导致错误。*
* **智能**：极佳的编辑器支持。处处皆可<abbr title="也被称为自动完成、智能感知">自动补全</abbr>，减少调试时间。

FastAPI est un framework web moderne et rapide (haute performance) pour la création d'API avec Python, basé sur les annotations de type standard de Python.

Les principales fonctionnalités sont :

import org.codelibs.fess.util.ComponentUtil;
import org.codelibs.fess.util.UpgradeUtil;
import org.codelibs.opensearch.runner.net.OpenSearchCurl;
import org.lastaflute.web.Execute;
import org.lastaflute.web.response.HtmlResponse;
import org.lastaflute.web.ruts.process.ActionRuntime;

public class AdminUpgradeAction extends FessAdminAction {

    public static final String ROLE = "admin-upgrade";

### Concurrencia + Paralelismo: Web + Machine Learning

Con **FastAPI** puedes aprovechar la concurrencia que es muy común para el desarrollo web (atractivo principal de NodeJS).

// Pos and End.
type Diagnostic struct {
	Pos      token.Pos
	End      token.Pos // optional
	Category string    // optional
	Message  string

	// URL is the optional location of a web page that provides
	// additional documentation for this diagnostic.
	//
	// If URL is empty but a Category is specified, then the
	// Analysis driver should treat the URL as "#"+Category.
	//

### Concurrency + Parallelism: Web + Machine Learning

With **FastAPI** you can take the advantage of concurrency that is very common for web development (the same main attraction of NodeJS).
