# Dependencies

**FastAPI** has a very powerful but intuitive **<abbr title="also known as components, resources, providers, services, injectables">Dependency Injection</abbr>** system.

It is designed to be very simple to use, and to make it very easy for any developer to integrate other components with **FastAPI**.

## What is "Dependency Injection"

    try {
      val provider = Proxy.getInvocationHandler(getMethod.invoke(null, sslSocket)) as AlpnProvider
      if (!provider.unsupported && provider.selected == null) {
        log("ALPN callback dropped: HTTP/2 is disabled. " + "Is alpn-boot on the boot class path?")
        return null
      }
      return if (provider.unsupported) null else provider.selected
    } catch (e: InvocationTargetException) {

### 3. Start the MinIO Server

```sh
export MINIO_ROOT_USER=minio
export MINIO_ROOT_PASSWORD=minio123
minio server ~/export
```

> The KES instance at `https://play.min.io:7373` is meant to experiment and provides a way to get started quickly.
> Note that anyone can access or delete master keys at `https://play.min.io:7373`. You should run your own KES
> instance in production.

## Configuration Guides

 * whose edges have associated non-unique values.
 *
 * <p>A graph is composed of a set of nodes and a set of edges connecting pairs of nodes.
 *
 * <p>There are three primary interfaces provided to represent graphs. In order of increasing
 * complexity they are: {@link Graph}, {@link ValueGraph}, and {@link Network}. You should generally
 * prefer the simplest interface that satisfies your use case. See the <a

 * elements' text contents. When possible, avoid manual escaping by using templating systems and
 * high-level APIs that provide autoescaping. For example, consider <a
 * href="http://www.xom.nu/">XOM</a> or <a href="http://www.jdom.org/">JDOM</a>.
 *
 * <p><b>Note:</b> Currently the escapers provided by this class do not escape any characters
 * outside the ASCII character range. Unlike HTML escaping the XML escapers will not escape

   * failed future if any of the items fails.
   *
   * <p>Canceling this future will attempt to cancel all the component futures, and if any of the
   * provided futures fails or is canceled, this one is, too.
   *
   * @param futures futures to combine
   * @return a future that provides a list of the results of the component futures
   * @since 10.0
