# Héberger en propre les ressources statiques de l’UI des docs personnalisées { #custom-docs-ui-static-assets-self-hosting }

Les documents de l’API utilisent **Swagger UI** et **ReDoc**, et chacune nécessite des fichiers JavaScript et CSS.

    Read more about it in the
    [FastAPI docs for Configure Swagger UI](https://fastapi.tiangolo.com/how-to/configure-swagger-ui/)
    and the [FastAPI docs for Custom Docs UI Static Assets (Self-Hosting)](https://fastapi.tiangolo.com/how-to/custom-docs-ui-assets/).

 * It is recommended (but not required) to also explicitly declare which core specs your project depends on to help optimize the caching
 * behavior.
 * <i>For example:</i>
 * <pre>
 * restResources {
 *   restApi {
 *     includeCore 'index', 'cat'
 *     includeXpack 'enrich'
 *   }
 * }
 * </pre>

 * The [CacheControl] class can configure request caching directives and parse response caching
 * directives. It even offers convenient constants [CacheControl.FORCE_NETWORK] and
 * [CacheControl.FORCE_CACHE] that address the use cases above.

If you are paying for 3 servers but you are using only a little bit of their RAM and CPU, you are probably **wasting money** 💸, and probably **wasting server electric power** 🌎, etc.

- Den Header `Cache-Control: no-cache` setzen, um **Caching** des Streams zu verhindern.
- Einen speziellen Header `X-Accel-Buffering: no` setzen, um **Buffering** in einigen Proxys wie Nginx zu verhindern.

* Set the `Cache-Control: no-cache` header to **prevent caching** of the stream.
* Set a special header `X-Accel-Buffering: no` to **prevent buffering** in some proxies like Nginx.

# 自托管自定义文档 UI 静态资源 { #custom-docs-ui-static-assets-self-hosting }

API 文档使用 Swagger UI 和 ReDoc，它们各自需要一些 JavaScript 和 CSS 文件。

默认情况下，这些文件从一个 <abbr title="Content Delivery Network - 内容分发网络: 一种服务，通常由多台服务器组成，用于提供静态文件，如 JavaScript 和 CSS。它常用于从更接近客户端的服务器提供这些文件，从而提升性能。">CDN</abbr> 提供。

不过你可以自定义：可以指定特定的 CDN，或自行提供这些文件。

## 为 JavaScript 和 CSS 自定义 CDN { #custom-cdn-for-javascript-and-css }

- **Configuration**: Allows the build structure and work, such as tasks, to be specified. This includes the project model, the DSL and so on.
- **Execution**: Runs the work efficiently. This includes scheduling, execution, caching and so on.

#### Software development platform

This is a general purpose platform that builds on the core automation platform to add support for the automation of software development.
