在此，我们简单回顾一下 **FastAPI** 的历史。

## 备选方案 { #alternatives }

有那么几年，我曾领导数个开发团队为诸多复杂需求创建各种 API，这些需求包括机器学习、分布系统、异步任务、NoSQL 数据库等领域。

作为工作的一部分，我需要调研很多备选方案、还要测试并且使用这些备选方案。

**FastAPI** 其实只是延续了这些前辈的历史。

正如[备选方案](alternatives.md)一章所述：

没有大家之前所做的工作，**FastAPI** 就不会存在。

以前创建的这些工具为它的出现提供了灵感。

여기서 그 역사에 대해 간단히 설명하겠습니다.

## 대안 { #alternatives }

저는 여러 해 동안 복잡한 요구사항(머신러닝, 분산 시스템, 비동기 작업, NoSQL 데이터베이스 등)을 가진 API를 만들면서 여러 개발 팀을 이끌어 왔습니다.

그 과정에서 많은 대안을 조사하고, 테스트하고, 사용해야 했습니다.

**FastAPI**의 역사는 상당 부분 그 이전에 있던 도구들의 역사입니다.

[대안](alternatives.md) 섹션에서 언급된 것처럼:

**FastAPI**는 다른 사람들이 이전에 해온 작업이 없었다면 존재하지 않았을 것입니다.

- **Cross-Language Compatibility:**
Java serialization is inherently Java-centric and does not support cross-language scenarios well.

- **Type Safety:**
Java serialization does not enforce type safety as strictly as some alternatives, potentially leading to runtime errors.

## Decision

We do not use Java serialization.
Instead, we use custom serialization where we explicitly describe how data objects should be serialized and deserialized.
