**Typer** é o irmão menor do FastAPI. E seu propósito é ser o **FastAPI das _CLIs_**. ⌨️ 🚀

## Requisitos

FastAPI está nos ombros de gigantes:

* <a href="https://www.starlette.io/" class="external-link" target="_blank">Starlette</a> para as partes web.

    * <a href="https://fastapi.tiangolo.com/features/" class="external-link" target="_blank">**Viele weitere Funktionen**</a>, einschließlich automatischer Validierung, Serialisierung, interaktiver Dokumentation,...

            return resolveCalled;
        }

        public Class<?> getLastCredentialType() {
            return lastCredentialType;
        }

        public Function<?, ?> getLastFunction() {
            return lastFunction;
        }
    }

    // Inner class for test credential
    private static class TestLoginCredential implements LoginCredential {
        private final String username;

```console
$ pip install fastapi

---> 100%
```

</div>

你同時也會需要 ASGI 伺服器用於生產環境，像是 <a href="https://www.uvicorn.org" class="external-link" target="_blank">Uvicorn</a> 或 <a href="https://github.com/pgjones/hypercorn" class="external-link" target="_blank">Hypercorn</a>。

<div class="termy">

```console
$ pip install "uvicorn[standard]"

---> 100%
```

</div>

## 範例

## Installation

<div class="termy">

```console
$ pip install fastapi

---> 100%
```

</div>

### Testen Sie es

Öffnen Sie Ihren Browser unter <a href="http://127.0.0.1:8000" class="external-link" target="_blank">http://127.0.0.1:8000.</a>

Sie werden folgende JSON-Response sehen:

```JSON
{"message": "Hello World"}
```

### Interaktive API-Dokumentation

Gehen Sie als Nächstes auf <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs </a>.

* <a href="https://github.com/swagger-api/swagger-ui" class="external-link" target="_blank"><strong>Swagger UI</strong></a>, met interactieve interface, maakt het mogelijk je API rechtstreeks vanuit de browser aan te roepen en te testen.

* Alternatieve API-documentatie met <a href="https://github.com/Rebilly/ReDoc" class="external-link" target="_blank"><strong>ReDoc</strong></a>.

  // This exclusion doesn't exclude the TOMBSTONE objects we set. So 'done' NEW futures will look
  // larger than they are.
  @SuppressWarnings("FutureReturnValueIgnored")
  @Footprint(exclude = {Runnable.class, Executor.class, Thread.class, Exception.class})
  public Object measureSize() {
    for (Thread thread : blockedThreads) {
      thread.interrupt();
    }
    blockedThreads.clear();
    Facade<Object> f = impl.newFacade();

* **Standards-based**: Gebaseerd op (en volledig verenigbaar met) open standaarden voor API's: <a href="https://github.com/OAI/OpenAPI-Specification" class="external-link" target="_blank">OpenAPI</a> (voorheen bekend als Swagger) en <a href="https://json-schema.org/" class="external-link" target="_blank">JSON Schema</a>.
