一个不太明显而又特别的优势是，你可以为你的API针对不同的**编程语言**来**生成客户端**(有时候被叫做 <abbr title="Software Development Kits">**SDKs**</abbr> )。

## OpenAPI 客户端生成

有许多工具可以从**OpenAPI**生成客户端。

一个常见的工具是 <a href="https://openapi-generator.tech/" class="external-link" target="_blank">OpenAPI Generator</a>。

如果您正在开发**前端**，一个非常有趣的替代方案是 <a href="https://github.com/hey-api/openapi-ts" class="external-link" target="_blank">openapi-ts</a>。

## 生成一个 TypeScript 前端客户端
