For example, you might want to try <a href="https://speakeasyapi.dev/?utm_source=fastapi+repo&utm_medium=github+sponsorship" class="external-link" target="_blank">Speakeasy</a>.

There are also several other companies offering similar services that you can search and find online. 🤓

## Generate a TypeScript Frontend Client

Let's start with a simple FastAPI application:

=== "Python 3.9+"

Django REST framework was created to be a flexible toolkit for building Web APIs using Django underneath, to improve its API capabilities.

It is used by many companies including Mozilla, Red Hat and Eventbrite.

It was one of the first examples of **automatic API documentation**, and this was specifically one of the first ideas that inspired "the search for" **FastAPI**.

!!! note

Ce "attendre quelque chose d'autre" fait généralement référence à des opérations <abbr title="Input/Output ou Entrées et Sorties ">I/O</abbr> qui sont relativement "lentes" (comparées à la vitesse du processeur et de la mémoire RAM) telles qu'attendre que :

* de la donnée soit envoyée par le client à travers le réseau
* de la donnée envoyée depuis votre programme soit reçue par le client à travers le réseau

Then the Python code in your application would be equivalent to something like:

```Python
if "johndoe" == "stanleyjobson" and "love123" == "swordfish":
    ...
```

Mais vous pouvez également utiliser <a href="https://typer.tiangolo.com/typer-cli/" class="external-link" target="_blank">Typer CLI</a>, et vous obtiendrez l'auto-complétion dans votre terminal pour les commandes après l'achèvement de l'installation.

Si vous installez Typer CLI, vous pouvez installer la complétion avec :

<div class="termy">

```console
$ typer --install-completion

Django REST framework foi criado para ser uma caixa de ferramentas flexível para construção de APIs web utilizando Django por baixo, para melhorar suas capacidades de API.

Ele é utilizado por muitas companhias incluindo Mozilla, Red Hat e Eventbrite.

Ele foi um dos primeiros exemplos de **documentação automática de API**, e essa foi especificamente uma das primeiras idéias que inspirou "a busca por" **FastAPI**.
