In these cases you can use `root_path` to configure your application.

The `root_path` is a mechanism provided by the ASGI specification (that FastAPI is built on, through Starlette).

The `root_path` is used to handle these specific cases.

And it's also used internally when mounting sub-applications.

## Proxy with a stripped path prefix

The OpenAPI schema is what powers the two interactive documentation systems included.

And there are dozens of alternatives, all based on OpenAPI. You could easily add any of those alternatives to your application built with **FastAPI**.

You could also use it to generate code automatically, for clients that communicate with your API. For example, frontend, mobile or IoT applications.

## Recap, step by step

```console
// Use o comando "build-all", isso leverá um tempinho
$ python ./scripts/docs.py build-all

### Migration

Check out the [Pydantic migration guide](https://docs.pydantic.dev/2.0/migration/).

For the things that need changes in your Pydantic models, the Pydantic team built [`bump-pydantic`](https://github.com/pydantic/bump-pydantic).

* API keys in:
    * Headers.
    * Query parameters.
    * Cookies, etc.

Plus all the security features from Starlette (including **session cookies**).

All built as reusable tools and components that are easy to integrate with your systems, data stores, relational and NoSQL databases, etc.

### Dependency Injection

Other common terms for this same idea of "dependency injection" are:

* resources
* providers
* services
* injectables
* components

## **FastAPI** plug-ins

<div class="termy">

```console
// Verwenden Sie das Kommando „build-all“, das wird ein wenig dauern
$ python ./scripts/docs.py build-all

Building docs for: en
Building docs for: es

</div>

Dadurch werden alle diese unabhängigen MkDocs-Sites für jede Sprache erstellt, kombiniert und das endgültige Resultat unter `./site/` gespeichert.
