## Self-hosting JavaScript and CSS for docs

Self-hosting the JavaScript and CSS could be useful if, for example, you need your app to keep working even while offline, without open Internet access, or in a local network.

Here you'll see how to serve those files yourself, in the same FastAPI app, and configure the docs to use them.

### Project file structure

* Add docs for [self-serving docs' (Swagger UI) static assets](https://fastapi.tiangolo.com/advanced/extending-openapi/#self-hosting-javascript-and-css-for-docs), e.g. to use the docs offline, or without Internet. Initial PR [#557](https://github.com/tiangolo/fastapi/pull/557) by [@svalouch](https://github.com/svalouch).
